Upgraded to 12.04 now wifi doesn't work

- by Benito Kestelman

My laptop's wifi stopped working when I upgraded to Ubuntu 12.04 (wired works). I just reinstalled 12.04 over my old 12.04 on which wifi didn't work either in an attempt to restore any settings I may have accidentally changed, but it still doesn't work. I also used a wired connection to install updates in case this bug has been fixed, but it has not.

Is Software Engineering Dead? [closed]

- by nik

Right from Jeff's blog: Software Engineering: Dead? I was utterly floored when I read this new IEEE article by Tom DeMarco (pdf). See if you can tell why. He quotes DeMarco, "I'm gradually coming to the conclusion that software engineering is an idea whose time has come and gone". Further, "What DeMarco seems to be saying -- and, at least, what I am definitely saying -- is that control is ultimately illusory on software development projects." I am writing these lines without context to invoke reading of the related subject. What are the views of the programming community here? I have started to realize that a community wiki is not getting the right amount of participation here. That is the reason I left this question out in the open, while still contemplating a change to CW. It was closed once, and I thought that was the end of it. But, now I see it was reopened and has more answers (all of which I have not yet read). However, I see a lot of CW requests and am forced to reconsider that. This is how I intend to make the CW decision here. There is a comment by Neil Butterworth requesting a CW at 12 upvotes -- "should be community wiki" There is a comment by Lance Roberts requesting no CW at 0 upvotes -- "+1 for not putting it in community wiki" The difference is 12 for a CW request at the moment If this difference becomes 5 more (that is 17), I'll move this question to CW, and it will not return back from there Of course, there is also a close vote at the moment; the question may be closed again.

Why can't decimal numbers be represented exactly in binary?

- by Barry Brown

There have been several questions posted to SO about floating-point representation. For example, the decimal number 0.1 doesn't have an exact binary representation, so it's dangerous to use the == operator to compare it to another floating-point number. I understand the principles behind floating-point representation. What I don't understand is why, from a mathematical perspective, are the numbers to the right of the decimal point any more "special" that the ones to the left? For example, the number 61.0 has an exact binary representation because the integral portion of any number is always exact. But the number 6.10 is not exact. All I did was move the decimal one place and suddenly I've gone from Exactopia to Inexactville. Mathematically, there should be no intrinsic difference between the two numbers -- they're just numbers. By contrast, if I move the decimal one place in the other direction to produce the number 610, I'm still in Exactopia. I can keep going in that direction (6100, 610000000, 610000000000000) and they're still exact, exact, exact. But as soon as the decimal crosses some threshold, the numbers are no longer exact. What's going on? Edit: to clarify, I want to stay away from discussion about industry-standard representations, such as IEEE, and stick with what I believe is the mathematically "pure" way. In base 10, the positional values are: ... 1000 100 10 1 1/10 1/100 ... In binary, they would be: ... 8 4 2 1 1/2 1/4 1/8 ... There are also no arbitrary limits placed on these numbers. The positions increase indefinitely to the left and to the right.

How to efficiently compare the sign of two floating-point values while handling negative zeros

- by François Beaune

Given two floating-point numbers, I'm looking for an efficient way to check if they have the same sign, given that if any of the two values is zero (+0.0 or -0.0), they should be considered to have the same sign. For instance, SameSign(1.0, 2.0) should return true SameSign(-1.0, -2.0) should return true SameSign(-1.0, 2.0) should return false SameSign(0.0, 1.0) should return true SameSign(0.0, -1.0) should return true SameSign(-0.0, 1.0) should return true SameSign(-0.0, -1.0) should return true A naive but correct implementation of SameSign in C++ would be: bool SameSign(float a, float b) { if (fabs(a) == 0.0f || fabs(b) == 0.0f) return true; return (a >= 0.0f) == (b >= 0.0f); } Assuming the IEEE floating-point model, here's a variant of SameSign that compiles to branchless code (at least with with Visual C++ 2008): bool SameSign(float a, float b) { int ia = binary_cast<int>(a); int ib = binary_cast<int>(b); int az = (ia & 0x7FFFFFFF) == 0; int bz = (ib & 0x7FFFFFFF) == 0; int ab = (ia ^ ib) >= 0; return (az | bz | ab) != 0; } with binary_cast defined as follow: template <typename Target, typename Source> inline Target binary_cast(Source s) { union { Source m_source; Target m_target; } u; u.m_source = s; return u.m_target; } I'm looking for two things: A faster, more efficient implementation of SameSign, using bit tricks, FPU tricks or even SSE intrinsics. An efficient extension of SameSign to three values.

Will a Ph. D. in Computer Science help?

- by Francisco Garcia

I am close to my 30s and still learning about programming and software engineering. Like most people who like their profession I truly believe that I should aim to improve and keep updated. One of the things I do is reading technical papers from professional publications (IEEE and ACM) but I admit there are very good bloggers out there too. Lately I started to think (should I say realize?) that Ph. D people actually are expected to expand constantly their knowledge, but little is expected from lower classes once they know enough This made me think that maybe having a Ph. D will help to have more... respect? but I also believe that I am already getting old for that. Futhermore I see many master and doctor programs that does not seem to add any value over hard experience and self learning. I belive that a degree in computer science, althought not necessary, can lay out a good base for programming work. However: What can a Ph. D. degree give you that you cannot learn on your own? (if you are not into something VERY specific and want to work in a non academic environment)

How to write a generic USB Host Driver for Printers from various vendors?

- by Ullas

I want to develop a USB host on an embedded device that will talk to printers from various vendors. Drivers for the vendor specific printers would be available on PC which is ultimately communicating with printer but my device is facilitating this communication and needs to perform the basic handshaking/setup of the printer (i.e, it needs to know when the printer is connected, what are the socket IDs that needs to be opened for CTRL and DATA transmissions etc). All of these printers are supposed to comply with IEEE 1284.4 standards but I see that many of them vary quiet a bit. One approach I have is to take the USB traces of handshaking from each of these printers and write various sections of code respectively (I know, that sounds ridiculous!). Is there a generic way to do this? Is there any available forum where these standard informations are mentioned? For eg: EPSON uses 'EPSON-CTRL' and 'EPSON-DATA' for its control and data services which needs to be provided to get the socket ID for these services. I am pretty sure HPs, Canon's etc would have their own service names as well. As per the standards, this was supposed to be captured in IANA but I dont see anything there. Any help on this would be greatly appreciated. Thanks and regards, Ullas

Creating a new variable in C from only part of an existing u_char

- by Alex Kloss

I'm writing some C code to parse IEEE 802.11 frames, but I'm stuck trying to create a new variable whose length depends on the size of the frame itself. Here's the code I currently have: int frame_body_len = pkt_hdr->len - radio_hdr->len - wifi_hdr_len - 4; u_char *frame_body = (u_char *) (packet + radio_hdr->len + wifi_hdr_len); Basically, the frame consists of a header, a body, and a checksum at the end. I can calculate the length of the frame body by taking the length of the packet and subtracting the length of the two headers that appear before it (radio_hdr->len and wifi_hdr_len respectively), plus 4 bytes at the end for the checksum. However, how can I create the frame_body variable without the trailing checksum? Right now, I'm initializing it with the contents of the packet starting at the position after the two headers, but is there some way to start at that position and end 4 bytes before the end of packet? packet is a pointer to a u_char, if it helps. I'm a new C programmer, so any and all advice about my code you can give me would be much appreciated. Thanks!

Creating a dynamic lacp trunk from HP Procurve 2412zl to Proliant DL380 G7

- by Maalobs

I'm configuring an IEEE 802.3ad (LACP) dynamic trunk from a HP Procurve 2412zl (firmware version K.15.07) switch to a HP Proliant DL380 G7 server. The DL380 has 4 NICs and is running Win2008 R2, so I'm teaming the NICs together and leaving everything on the recommended "automatic" setting in the HP NIC configuration tool. The server is one of two, they'll be connected on interfaces F17-F20 and F21-F24 respectively on the switch. I need the servers in a separate VLAN, here is the configuration for the VLAN: vlan 10 name "Lab_Mgmt" untagged B2,F17-F24 ip address 172.22.71.3 255.255.255.0 tagged B21 exit There is a DHCP-relay into the VLAN 10 from another device beyond interface B21. The Advanced Traffic Management Guide says that in order to run a dynamic LACP trunk on another VLAN besides the DEFAULT_VLAN, you need to first enable GVRP and then use "forbid" to stop the interfaces from automatically joining DEFAULT_VLAN when the dynamic trunk is created. GVRP brings some other stuff with it that I don't want or need, so I disable it with "unknown-vlans disable" on all other interfaces. Here is how I do it: procurve-5412zl-1(config)# gvrp procurve-5412zl-1(config)# interface A1-A24,B1-B24,C1-C24,D1-D10,D13-D24,E1-E24, F1-F16,K1,K2 unknown-vlans disable procurve-5412zl-1(config)# vlan 1 forbid F17-F24 procurve-5412zl-1(config)# interface F17-F20 lacp active The result afterwards looks all successful: procurve-5412zl-1(config)# show trunks Load Balancing Method: L3-based (Default), L2-based if non-IP traffic Port | Name Type | Group Type ---- + -------------------------------- --------- + ------ -------- F17 | XYZTEAM3_NIC1 100/1000T | Dyn2 LACP F18 | XYZTEAM3_NIC2 100/1000T | Dyn2 LACP F19 | XYZTEAM3_NIC3 100/1000T | Dyn2 LACP F20 | XYZTEAM3_NIC4 100/1000T | Dyn2 LACP procurve-5412zl-1(config)# vlan 10 procurve-5412zl-1(vlan-10)# show lacp LACP LACP Trunk Port LACP Admin Oper Port Enabled Group Status Partner Status Key Key ---- ------- ------- ------- ------- ------- ------ ------ F17 Active Dyn2 Up Yes Success 0 0 F18 Active Dyn2 Up Yes Success 0 0 F19 Active Dyn2 Up Yes Success 0 0 F20 Active Dyn2 Up Yes Success 0 0 On the Proliant server, the NIC configuration Tool is also indicating that a 802.3ad dynamic trunk has been established. Everything should be good, but it isn't. The server is not getting an IP-address from the DHCP, which it does if I'm not enabling LACP. If I configure the server to a static IP-address on the VLAN 10 subnet, it can't even ping the switch IP-address, much less anything outside of the VLAN. The switch can't ping the server either. I did another attempt with F17-F20 tagged, and checking the box "Default Native Tag (VLAN 10)" in the NIC configuration tool on the server, but there was no difference. Does anyone have any idea what I might have missed?

Disk is spinning down each minute, unable to disable it

I played with spindown and APM settings of my Samsung discs and now they spin down every minute. I want to disable it, but it seems it does not accept any of the spindown time or APM values.

file corruption on read/write 2.6.32-22-server (happens across many kernels)

- by Jonathan

Hi Guys, I'm having an issue where after the server has been up for a period of time (~week/few days) the server will start reading corrupt data. For instance when I run a sha1sum of a file after a fresh boot it remains the same. However after a while I will start to get segfaults and from then on whenever I read this file I get a different sha1sum. I've checked S.M.A.R.T with long tests and I've run an extended memtest86+(12 passes) My lspci is as follows: 00:00.0 Host bridge: Advanced Micro Devices [AMD] RS780 Host Bridge 00:01.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (int gfx) 00:06.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 2) 00:07.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 3) 00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA Controller [AHCI mode] 00:12.0 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller 00:12.1 USB Controller: ATI Technologies Inc SB700 USB OHCI1 Controller 00:12.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller 00:13.0 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller 00:13.1 USB Controller: ATI Technologies Inc SB700 USB OHCI1 Controller 00:13.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller 00:14.0 SMBus: ATI Technologies Inc SBx00 SMBus Controller (rev 3c) 00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller 00:14.3 ISA bridge: ATI Technologies Inc SB700/SB800 LPC host controller 00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge 00:14.5 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI2 Controller 00:18.0 Host bridge: Advanced Micro Devices [AMD] K10 [Opteron, Athlon64, Sempron] HyperTransport Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K10 [Opteron, Athlon64, Sempron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K10 [Opteron, Athlon64, Sempron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K10 [Opteron, Athlon64, Sempron] Miscellaneous Control 00:18.4 Host bridge: Advanced Micro Devices [AMD] K10 [Opteron, Athlon64, Sempron] Link Control 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3300 Graphics 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller 02:00.0 Ethernet controller: Atheros Communications Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (rev b0) 03:00.0 FireWire (IEEE 1394): VIA Technologies, Inc.

I don't believe it's the software raid however as this affects files also hosted on non-raid partitions so I don't know.

Configure spanning tree from HP to Cisco hardware

- by Tim Brigham

I have three switches I'd like to configure in a loop - a Cisco stack (3750s) and two HP 2900 series. Each is connected to the next with a 10 gig backplane of one form or another. How do I configure the spanning tree on these systems to make this function correctly? From the documents I've looked at it looks like I need to set both sets of hardware to use MST mode but I'm not sure past that point. The trunking, etc is all set up as needed.

debian packages version convention

I'm using debian/Ubuntu, and get confused about versions of packages. When using dpkg -l command, I get: ii vim 2:7.3.429-2ubuntu2.1 Vi IMproved - enhanced vi editor ii vim-common 2:7.3.429-2ubuntu2.1 Vi IMproved - Common files ii vim-runtime 2:7.3.429-2ubuntu2.1 Vi IMproved - Runtime files ii vim-tiny 2:7.3.429-2ubuntu2.1 Vi IMproved - enhanced vi editor - compact version ii virt-what 1.11-1 detect if we are running in a virtual machine ii w3m 0.5.3-5ubuntu1 WWW browsable pager with excellent tables/frames support ii watershed 6 reduce superfluous executions of idempotent command ii wget 1.13.4-2ubuntu1 retrieves files from the web ii whiptail 0.52.11-2ubuntu10 Displays user-friendly dialog boxes from shell scripts ii whoopsie 0.1.33 Ubuntu crash database submission daemon ii wimlib9 1.5.0-1~webupd8~precise Library to extract, create, modify, and mount WIM files ii wimtools 1.5.0-1~webupd8~precise Tools to extract, create, modify, and mount WIM files ii wireless-tools 30~pre9-5ubuntu2 Tools for manipulating Linux Wireless Extensions ii wpasupplicant 0.7.3-6ubuntu2.1 client support for WPA and WPA2 (IEEE 802.11i) ii x11-common 1:7.6+12ubuntu2 X Window System (X.Org) infrastructure ii x11-utils 7.6+4ubuntu0.1 X11 utilities ii xauth 1:1.0.6-1 X authentication utility ii xbitmaps 1.1.1-1 Base X bitmaps ii xclip 0.12-1 command line interface to X selections ii xfonts-encodings 1:1.0.4-1ubuntu1 Encodings for X.Org fonts ii xfonts-utils 1:7.6+1 X Window System font utility programs ii xkb-data 2.5-1ubuntu1.3 X Keyboard Extension (XKB) configuration data ii xml-core 0.13 XML infrastructure and XML catalog file support rc xpdf 3.02-21build1 Portable Document Format (PDF) reader ii xterm 271-1ubuntu2.1 X terminal emulator ii xz-lzma 5.1.1alpha+20110809-3 XZ-format compression utilities - compatibility commands ii xz-utils 5.1.1alpha+20110809-3 XZ-format compression utilities ii zabbix-agent 1:1.8.11-1 network monitoring solution - agent ii zlib1g 1:1.2.3.4.dfsg-3ubuntu4 compression library - runtime ii zlib1g-dev 1:1.2.3.4.dfsg-3ubuntu4 compression library - development ii zsh 4.3.17-1ubuntu1 shell with lots of features The third column is version, but it all messed up in a way I can't understand. I mean, different packages use total different naming specification. Here are the major questions: Why there are ubuntu in them, and there are not? what all the special -~+ mean? alpha and build, dfsg, what are they? Can I just use them casually? vim and other packages have 2:, what does that mean? How version comparison works, since they can be so different? Can anyone please explain this to me? Or where can I find an official document? Thanks in advance.

Linksys WiFi usb dongle and linux woes

- by MrStatic

I have a Linksys WUSB54GC usb dongle and I have exhausted every thing I know about making this thing work in linux. I am using Fedora 13. Since it is not ready I can not view any networks. Any ideas would be great. tail of the system log Jun 2 20:14:35 localhost kernel: usb 1-7: new high speed USB device using ehci_hcd and address 8 Jun 2 20:14:35 localhost kernel: usb 1-7: New USB device found, idVendor=1737, idProduct=0077 Jun 2 20:14:35 localhost kernel: usb 1-7: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Jun 2 20:14:35 localhost kernel: usb 1-7: Product: 802.11 g WLAN Jun 2 20:14:35 localhost kernel: usb 1-7: Manufacturer: Ralink Jun 2 20:14:35 localhost kernel: usb 1-7: SerialNumber: 1.0 Jun 2 20:14:35 localhost kernel: Registered led device: rt2800usb-phy3::radio Jun 2 20:14:35 localhost kernel: Registered led device: rt2800usb-phy3::assoc Jun 2 20:14:35 localhost kernel: Registered led device: rt2800usb-phy3::quality Jun 2 20:14:35 localhost NetworkManager[1367]: <info> found WiFi radio killswitch rfkill3 (at /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-7/1-7:1.0/ieee80211/phy3/rfkill3) (driver <unknown>) Jun 2 20:14:35 localhost kernel: rt2800usb 1-7:1.0: firmware: requesting rt2870.bin Jun 2 20:14:35 localhost NetworkManager[1367]: <info> (wlan0): driver supports SSID scans (scan_capa 0x01).

Ubuntu hardware wireless switch has no effect after suspend and 13.10 upgrade

- by blaineh

I'm posting this on SU after it stalled on askubuntu. I hope someone here can help! If you'd prefer to answer on AU itself, here's the link: http://askubuntu.com/questions/365177/hardware-wireless-switch-has-no-effect-after-suspend-and-13-10-upgrade Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Edit. This morning, I had had the laptop suspended all night, and then when I tried to awake it, it simply wouldn't. It would try, and then it would sleep again (I guess it felt a little bit like me! </badjoke>). Is it possible these problems are related? Edit. I don't have enough reputation on SU proper to post links to pastebins and other questions I've tried, so I'm putting them in comments, and of course they're available in the original question.

how to setup kismet.conf on Ubuntu

- by Registered User

I installed Kismet on my Ubuntu 10.04 machine as apt-get install kismet every thing seems to work fine. but when I launch it I see following error kismet Launching kismet_server: //usr/bin/kismet_server Suid priv-dropping disabled. This may not be secure. No specific sources given to be enabled, all will be enabled. Non-RFMon VAPs will be destroyed on multi-vap interfaces (ie, madwifi-ng) Enabling channel hopping.

FATAL: Please configure at least one packet source. Kismet will not function if no packet sources are defined in kismet.conf or on the command line.

I followed this guide http://www.ubuntugeek.com/kismet-an-802-11-wireless-network-detector-sniffer-and-intrusion-detection-system.html#more-1776 how ever in kismet.conf I am not clear with following line source=none,none,addme as to what should I change this to. lspci -vnn shows 0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) Subsystem: Dell Device [1028:000c] Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f69fc000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information <?> Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting <?> Capabilities: [13c] Virtual Channel <?> Capabilities: [160] Device Serial Number Capabilities: [16c] Power Budgeting <?> Kernel driver in use: wl Kernel modules: wl, ssb and iwconfig shows lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11bg ESSID:"WIKUCD" Mode:Managed Frequency:2.462 GHz Access Point: <00:43:92:21:H5:09> Bit Rate=11 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Managementmode:All packets received Link Quality=1/5 Signal level=-81 dBm Noise level=-90 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:169 Invalid misc:0 Missed beacon:0 So what should I be putting in place of source=none,none,addme with output I mentioned above ?

HttpClient POST fails to submit the form

- by Jayomat

Hi, I'm writing an app to check for the bus timetable's. Therefor I need to post some data to a html page, submit it, and parse the resulting page with htmlparser. Though it may be asked a lot, can some one help me identify if 1) this page does support post/get (I think it does) 2) which fields I need to use? 3) How to make the actual request? this is my code so far: String url = "http://busspur02.aseag.de/bs.exe?Cmd=RV&Karten=true&DatumT=30&DatumM=4&DatumJ=2010&ZeitH=&ZeitM=&Suchen=%28S%29uchen&GT0=&HT0=&GT1=&HT1="; String charset = "CP1252"; System.out.println("startFrom: "+start_from); System.out.println("goTo: "+destination); //String tag.v List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("HTO", start_from)); params.add(new BasicNameValuePair("HT1", destination)); params.add(new BasicNameValuePair("GTO", "Aachen")); params.add(new BasicNameValuePair("GT1", "Aachen")); params.add(new BasicNameValuePair("DatumT", day)); params.add(new BasicNameValuePair("DatumM", month)); params.add(new BasicNameValuePair("DatumJ", year)); params.add(new BasicNameValuePair("ZeitH", hour)); params.add(new BasicNameValuePair("ZeitM", min)); UrlEncodedFormEntity query = new UrlEncodedFormEntity(params, charset); HttpPost post = new HttpPost(url); post.setEntity(query); InputStream response = new DefaultHttpClient().execute(post).getEntity().getContent(); // Now do your thing with the facebook response. String source = readText(response,"CP1252"); Log.d(TAG_AVV,response.toString()); System.out.println("STREAM "+source); One person also gave me a hint to use firebug to read what's going on at the page, but I don't really understand what to look for, or more precisely, how to use the provided information. I also find it confusing, for example, that when I enter the data by hand, the url says, for example, "....HTO=Kaiserplatz&...", but in Firebug, the same Kaiserplatz is connected to a different field, in this case: \<\td class="Start3" Kaiserplatz <\/td (I inserted \ to make it visible) The last line in my code prints the html page, but without having send a request.. it's printed as if there was no input at all... My app is almost done, I hope someone can help me out to finish it! thanks in advance EDIT: this is what the s.o.p returns: (At some point there actually is some input, but only the destination ???)

Atheros Wireless card shows up as two different models?

- by geermc4

Hi I've been fighting these wireless drivers for a few days and just recently i noticed that the model the Wireless controller appears in lspci is different sometimes. This is the data i have after installing Ubuntu Server 64 bit ~# lspci -k .... 04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Subsystem: AzureWave Device 1d89 Kernel driver in use: ath9k Kernel modules: ath9k ran some updates, restarted, all was good, all though it did say that linux-headers-server linux-image-server linux-server where beeing kept back. After that i installed ubuntu-desktop (aptitude install ubuntu-desktop --without-recommends) restarted and not only is the wireless not working anymore, but the hardware is listed as a different card ~# lspci -k .... 04:00.0 Ethernet controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) has no available drivers for it, still i tried to modprobe ath9k, they show up in lsmod as loaded, but still iw list shows nothing. this is what it looked like before the ubuntu-desktop instalation Wiphy phy0 Band 1: Capabilities: 0x11ce HT20/HT40 SM Power Save disabled RX HT40 SGI TX STBC RX STBC 1-stream Max AMSDU length: 3839 bytes DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 8 usec (0x06) HT TX/RX MCS rate indexes supported: 0-7 Frequencies: * 2412 MHz [1] (14.0 dBm) * 2417 MHz [2] (15.0 dBm) * 2422 MHz [3] (15.0 dBm) * 2427 MHz [4] (15.0 dBm) * 2432 MHz [5] (15.0 dBm) * 2437 MHz [6] (15.0 dBm) * 2442 MHz [7] (15.0 dBm) * 2447 MHz [8] (15.0 dBm) * 2452 MHz [9] (15.0 dBm) * 2457 MHz [10] (15.0 dBm) * 2462 MHz [11] (15.0 dBm) * 2467 MHz [12] (15.0 dBm) (passive scanning) * 2472 MHz [13] (14.0 dBm) (passive scanning) * 2484 MHz [14] (17.0 dBm) (passive scanning) Bitrates (non-HT): * 1.0 Mbps * 2.0 Mbps (short preamble supported) * 5.5 Mbps (short preamble supported) * 11.0 Mbps (short preamble supported) * 6.0 Mbps * 9.0 Mbps * 12.0 Mbps * 18.0 Mbps * 24.0 Mbps * 36.0 Mbps * 48.0 Mbps * 54.0 Mbps max # scan SSIDs: 4 max scan IEs length: 2257 bytes Coverage class: 0 (up to 0m) Supported Ciphers: * WEP40 (00-0f-ac:1) * WEP104 (00-0f-ac:5) * TKIP (00-0f-ac:2) * CCMP (00-0f-ac:4) * CMAC (00-0f-ac:6) Available Antennas: TX 0x1 RX 0x3 Configured Antennas: TX 0x1 RX 0x3 Supported interface modes: * IBSS * managed * AP * AP/VLAN * WDS * monitor * mesh point * P2P-client * P2P-GO software interface modes (can always be added): * AP/VLAN * monitor interface combinations are not supported Supported commands: * new_interface * set_interface * new_key * new_beacon * new_station * new_mpath * set_mesh_params * set_bss * authenticate * associate * deauthenticate * disassociate * join_ibss * join_mesh * remain_on_channel * set_tx_bitrate_mask * action * frame_wait_cancel * set_wiphy_netns * set_channel * set_wds_peer * connect * disconnect Supported TX frame types: * IBSS: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * managed: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP/VLAN: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * mesh point: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-client: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-GO: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 Supported RX frame types: * IBSS: 0x00d0 * managed: 0x0040 0x00d0 * AP: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * AP/VLAN: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * mesh point: 0x00b0 0x00c0 0x00d0 * P2P-client: 0x0040 0x00d0 * P2P-GO: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 Device supports RSN-IBSS. What's with the hardware change? If it has 2, how can i make the AR9285 always load and disable AR5008, or, is it the same and it's just showing it different? :| Oh and I've tried this on Ubuntu 10.04 server, xubuntu 12.04, ubuntu 12.04 desktop and server. Thanks in advanced. -- Here's some more info, i have it setup in 2 hard drives, 1 works and the other one i'm using to figure it out The one that works... # lshw -class network *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 06 serial: 54:04:a6:a3:3b:96 size: 1Gbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168e-2.fw ip=192.168.2.147 latency=0 link=yes multicast=yes port=MII speed=1Gbit/s resources: irq:43 ioport:e000(size=256) memory:d0004000-d0004fff memory:d0000000-d0003fff *-network description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:04:00.0 logical name: wlan0 version: 01 serial: 74:2f:68:4a:26:73 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.2.0-18-generic-pae firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:18 memory:fea00000-fea0ffff Here's where it doesn't # lshw -class network *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 06 serial: 54:04:a6:a3:3b:96 size: 1Gbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl_nic/rtl8168e-2.fw ip=192.168.2.160 latency=0 link=yes multicast=yes port=MII speed=1Gbit/s resources: irq:43 ioport:e000(size=256) memory:d0004000-d0004fff memory:d0000000-d0003fff *-network UNCLAIMED description: Ethernet controller product: AR5008 Wireless Network Adapter vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:04:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:fea00000-fea0ffff Update I've noticed that if i blacklist the ath9k and ath9k_common modules lspci gives me the AR9285, but then I need to modprobe ath9k for it to work, does this make any sense?

Computer Networks UNISA - Chap 8 – Wireless Networking

- by MarkPearl

After reading this section you should be able to Explain how nodes exchange wireless signals Identify potential obstacles to successful transmission and their repercussions, such as interference and reflection Understand WLAN architecture Specify the characteristics of popular WLAN transmission methods including 802.11 a/b/g/n Install and configure wireless access points and their clients Describe wireless MAN and WAN technologies, including 802.16 and satellite communications The Wireless Spectrum All wireless signals are carried through the air by electromagnetic waves. The wireless spectrum is a continuum of the electromagnetic waves used for data and voice communication. The wireless spectrum falls between 9KHZ and 300 GHZ. Characteristics of Wireless Transmission Antennas Each type of wireless service requires an antenna specifically designed for that service. The service’s specification determine the antenna’s power output, frequency, and radiation pattern. A directional antenna issues wireless signals along a single direction. An omnidirectional antenna issues and receives wireless signals with equal strength and clarity in all directions The geographical area that an antenna or wireless system can reach is known as its range Signal Propagation LOS (line of sight) uses the least amount of energy and results in the reception of the clearest possible signal. When there is an obstacle in the way, the signal may… pass through the object or be obsrobed by the object or may be subject to reflection, diffraction or scattering. Reflection – waves encounter an object and bounces off it. Diffraction – signal splits into secondary waves when it encounters an obstruction Scattering – is the diffusion or the reflection in multiple different directions of a signal Signal Degradation Fading occurs as a signal hits various objects. Because of fading, the strength of the signal that reaches the receiver is lower than the transmitted signal strength. The further a signal moves from its source, the weaker it gets (this is called attenuation) Signals are also affected by noise – the electromagnetic interference) Interference can distort and weaken a wireless signal in the same way that noise distorts and weakens a wired signal. Frequency Ranges Older wireless devices used the 2.4 GHZ band to send and receive signals. This had 11 communication channels that are unlicensed. Newer wireless devices can also use the 5 GHZ band which has 24 unlicensed bands Narrowband, Broadband, and Spread Spectrum Signals Narrowband – a transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies Broadband – uses a relatively wide band of the wireless spectrum and offers higher throughputs than narrowband technologies The use of multiple frequencies to transmit a signal is known as spread-spectrum technology. In other words a signal never stays continuously within one frequency range during its transmission. One specific implementation of spread spectrum is FHSS (frequency hoping spread spectrum). Another type is known as DSS (direct sequence spread spectrum) Fixed vs. Mobile Each type of wireless communication falls into one of two categories Fixed – the location of the transmitted and receiver do not move (results in energy saved because weaker signal strength is possible with directional antennas) Mobile – the location can change WLAN (Wireless LAN) Architecture There are two main types of arrangements Adhoc – data is sent directly between devices – good for small local devices Infrastructure mode – a wireless access point is placed centrally, that all devices connect with 802.11 WLANs The most popular wireless standards used on contemporary LANs are those developed by IEEE’s 802.11 committee. Over the years several distinct standards related to wireless networking have been released. Four of the best known standards are also referred to as Wi-Fi. They are…. 802.11b 802.11a 802.11g 802.11n These four standards share many characteristics. i.e. All 4 use half duplex signalling Follow the same access method Access Method 802.11 standards specify the use of CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to access a shared medium. Using CSMA/CA before a station begins to send data on an 802.11 network, it checks for existing wireless transmissions. If the source node detects no transmission activity on the network, it waits a brief period of time and then sends its transmission. If the source does detect activity, it waits a brief period of time before checking again. The destination node receives the transmission and, after verifying its accuracy, issues an acknowledgement (ACT) packet to the source. If the source receives the ACK it assumes the transmission was successful, – if it does not receive an ACK it assumes the transmission failed and sends it again. Association Two types of scanning… Active – station transmits a special frame, known as a prove, on all available channels within its frequency range. When an access point finds the probe frame, it issues a probe response. Passive – wireless station listens on all channels within its frequency range for a special signal, known as a beacon frame, issued from an access point – the beacon frame contains information necessary to connect to the point. Re-association occurs when a mobile user moves out of one access point’s range and into the range of another. Frames Read page 378 – 381 about frames and specific 802.11 protocols Bluetooth Networks Sony Ericson originally invented the Bluetooth technology in the early 1990s. In 1998 other manufacturers joined Ericsson in the Special Interest Group (SIG) whose aim was to refine and standardize the technology. Bluetooth was designed to be used on small networks composed of personal communications devices. It has become popular wireless technology for communicating among cellular telephones, phone headsets, etc. Wireless WANs and Internet Access Refer to pages 396 – 402 of the textbook for details.

Atheros AR2413 wireless not working after shutdown

- by Chandrasekhar

I am using a Ubuntu 11.04 on an Acer aspire 3680 laptop and my wifi is not working. I followed the below commands to install the madwifi driver: sudo su apt-get install subversion cd /usr/src svn checkout http://madwifi-project.org/svn/madwifi/trunk madwifi tar cfvz madwifi.tgz cd madwifi make && make install echo "blacklist ath5k" /etc/modprobe.d/blacklist.conf echo "ath_pci" /etc/modules modprobe ath_pci sudo reboot After installation I am facing the same problem. My wifi wont work after I shutdown. Infact it didn't work after suspend but I rectified that problem by the following commands: Command 1: sudo rmmod -f ath_pci sudo rfkill unblock all sudo modprobe ath_pci along with the command SUSPEND_MODULES=ath_pci added to the /etc/pm/config.d/madwifi directory. So if I suspend and then on my laptop the wifi loads well and doesn't create a problem. But if I shutdown my laptop the wifi never loads again and eachtime I have to run a Ubuntu 9.04 live CD to load it. I did try adding the Command 1 to the /etc/rc.local directory but still it doesn't work. So my question is: What should I do in order to make my wireless work without having to run a live CD of ubuntu 9.04 everytime after shutdown? Thanks.

Resultant of a polynomial with x^n–1

- by devin.omalley

Resultant of a polynomial with x^n–1 (mod p) I am implementing the NTRUSign algorithm as described in http://grouper.ieee.org/groups/1363/lattPK/submissions/EESS1v2.pdf , section 2.2.7.1 which involves computing the resultant of a polynomial. I keep getting a zero vector for the resultant which is obviously incorrect. private static CompResResult compResMod(IntegerPolynomial f, int p) { int N = f.coeffs.length; IntegerPolynomial a = new IntegerPolynomial(N); a.coeffs[0] = -1; a.coeffs[N-1] = 1; IntegerPolynomial b = new IntegerPolynomial(f.coeffs); IntegerPolynomial v1 = new IntegerPolynomial(N); IntegerPolynomial v2 = new IntegerPolynomial(N); v2.coeffs[0] = 1; int da = a.degree(); int db = b.degree(); int ta = da; int c = 0; int r = 1; while (db > 0) { c = invert(b.coeffs[db], p); c = (c * a.coeffs[da]) % p; IntegerPolynomial cb = b.clone(); cb.mult(c); cb.shift(da - db); a.sub(cb, p); IntegerPolynomial v2c = v2.clone(); v2c.mult(c); v2c.shift(da - db); v1.sub(v2c, p); if (a.degree() < db) { r *= (int)Math.pow(b.coeffs[db], ta-a.degree()); r %= p; if (ta%2==1 && db%2==1) r = (-r) % p; IntegerPolynomial temp = a; a = b; b = temp; temp = v1; v1 = v2; v2 = temp; ta = db; } da = a.degree(); db = b.degree(); } r *= (int)Math.pow(b.coeffs[0], da); r %= p; c = invert(b.coeffs[0], p); v2.mult(c); v2.mult(r); v2.mod(p); return new CompResResult(v2, r); } There is pseudocode in http://www.crypto.rub.de/imperia/md/content/texte/theses/da_driessen.pdf which looks very similar. Why is my code not working? Are there any intermediate results I can check? I am not posting the IntegerPolynomial code because it isn't too interesting and I have unit tests for it that pass. CompResResult is just a simple "Java struct".

I would like to install bonding with 4 links with mode 4. but only "download/receiving" works with bondig. for transmitting the system chooses one link. ifconfig bond0 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 inet addr:ip Bcast:ip Mask:255.255.255.248 inet6 addr: fe80::92e2:baff:fe0f:76b4/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:239187413 errors:0 dropped:10944 overruns:0 frame:0 TX packets:536902370 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14688536197 (13.6 GiB) TX bytes:799521192901 (744.6 GiB) eth2 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:54969488 errors:0 dropped:0 overruns:0 frame:0 TX packets:2537 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3374778591 (3.1 GiB) TX bytes:314290 (306.9 KiB) eth3 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:64935805 errors:0 dropped:1 overruns:0 frame:0 TX packets:2532 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3993499746 (3.7 GiB) TX bytes:313968 (306.6 KiB) eth4 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:57352105 errors:0 dropped:2 overruns:0 frame:0 TX packets:536894778 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3524236530 (3.2 GiB) TX bytes:799520265627 (744.6 GiB) eth5 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:61930025 errors:0 dropped:3 overruns:0 frame:0 TX packets:2540 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3796021948 (3.5 GiB) TX bytes:314274 (306.9 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:62 errors:0 dropped:0 overruns:0 frame:0 TX packets:62 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5320 (5.1 KiB) TX bytes:5320 (5.1 KiB) those are my configs: DEVICE="eth2" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth3" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth4" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth5" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE=bond0 IPADDR=<ip> BROADCAST=<ip> NETWORK=<ip> GATEWAY=<ip> NETMASK=<ip> USERCTL=no BOOTPROTO=none ONBOOT=yes NM_CONTROLLED=no cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: slow Aggregator selection policy (ad_select): stable Active Aggregator Info: Aggregator ID: 1 Number of ports: 4 Actor Key: 17 Partner Key: 11 Partner Mac Address: 00:24:51:12:63:00 Slave Interface: eth2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b4 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth3 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b5 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth4 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b6 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth5 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b7 Aggregator ID: 1 Slave queue ID: 0 /etc/modprobe.d/bonding.conf alias bond0 bonding options bond0 mode=4 miimon=100 updelay=200 #downdelay=200 xmit_hash_policy=layer3+4 lacp_rate=1 Linux: Linux 3.0.0+ #1 SMP Fri Oct 26 07:55:47 EEST 2012 x86_64 x86_64 x86_64 GNU/Linux what i've tried: downdelay=200 xmit_hash_policy=layer3+4 lacp_rate=1 mode 6

hostapd running on Ubuntu Server 13.04 only allows single station to connect when using wpa

- by user450688

Problem Only a single station can connect to hostapd at a time. Any single station can connect (W8, OSX, iOS, Nexus) but when two or more hosts are connected at the same time the first client loses its connectivity. However there are no connectivity issues when WPA is not used.

Enable wireless on Dell Inspiron 1300

- by Simon

As per subject, I've looked at various resources and attempted ndiswrapper solutions, found a one-click solution that lead to a 404 and this but none works. I've run all updates. Once I managed to lose my wired connection as well and had to reinstall. This is my first hour with Linux. iwconfig gives this before I do anything: lo no wireless extensions. wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry
