• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• Network throughput issue (ARP-related)

  - by Joel Coel

  The small college where I work is having some very strange network issues. I'm looking for any advice or ideas here. We were fine over the summer, but the trouble began few days after students returned to campus in force for the fall term. Symptoms The main symptom is that internet access will work, but it's very slow... often to the point of timeouts. As an example, a typical result from Speedtest.net will return .4Mbps download, but allow 3 to 8 Mbps upload speed. Lesser symptoms may include severely limited performance transferring data to and from our file server, or even in some cases the inability to log in to the computer (cannot reach the domain controller). The issue crosses multiple vlans, and has effected devices on nearly every vlan we operate. The issue does not impact all machines on the network. An unaffected machine will typically see at least 11Mbps download from speedtest.net, and perhaps much more depending on larger campus traffic patterns at the time. There is one variation on the larger issue. We have one vlan where users were unable to log into nearly all of the machines at all. IT staff would log in using a local administrator account (or in some cases cached credentials), and from there a release/renew or pinging the gateway would allow the machine to work... for a while. Complicating this issue is that this vlan covers our computer labs, which use software called Deep Freeze to completely reset the hard drives after a reboot. It could just the same issue manifesting differently because of stale data on machines that have not permanently altered low-level info for weeks. We were able to solve this, however, by creating a new vlan and moving the labs over to the new vlan wholesale. Instigations Eventually we noticed that the effected machines all had recent dhcp leases. We can predict when a machine will become "slow" by watching when a dhcp lease comes up for renewal. We played with setting the lease time very short for a test vlan, but all that did was remove our ability to predict when the machine would become slow. Machines with static IPs have pretty much always worked normally. Manually releasing/renewing an address will never cause a machine to become slow. In fact, in some cases this process has fixed a machine in that state. Most of the time, though, it doesn't help. We also noticed that mobile machines like laptops are likely to become slow when they cross to new vlans. Wireless on campus is divided up into "zones", where each zone maps to a small set of buildings. Moving to a new building can place you in a zone, thereby causing you to get a new address. A machine resuming from sleep mode is also very likely to be slow. Mitigations Sometimes, but not always, clearing the arp cache on an effected machine will allow it to work normally again. As already mentioned, releasing/renewing a local machine's IP address can fix that machine, but it's not guaranteed. Pinging the default gateway can also sometimes help with a slow machine. What seems to help most to mitigate the issue is clearing the arp cache on our core layer-3 switch. This switch is used for our dhcp system as the default gateway on all vlans, and it handles inter-vlan routing. The model is a 3Com 4900SX. To try to mitigate the issue, we have the cache timeout set on the switch all the way down to the lowest possible time, but it hasn't helped. I also put together a script that runs every few minutes to automatically connect to the switch and reset the cache. Unfortunately, this does not always work, and can even cause some machines to end up in the slow state for a short time (though these seem to correct themselves after a few minutes). We currently have a scheduled job that runs every 10 minutes to force the core switch to clear it's ARP cache, but this is far from perfect or desirable. Reproduction We now have a test machine that we can force into the slow state at will. It is connected to a switch with ports set up for each of our vlans. We make the machine slow by connecting to different vlans, and after a new connection or two it will be slow. It's also worth noting in this section that this has happened before at the start of prior terms, but in the past the problem has gone away on it's own after a few days. It solved itself before we had a chance to do much diagnostic work... hence why we've allowed it to drag so long into the term this time 'round; the expectation was this would be a short-lived situation. Other Factors It's worth mentioning that we have had about half a dozen switches just outright fail over the last year. These are mainly 2003/2004-era 3Coms (mostly 4200's) that were all put in at about the same time. They should still be covered under warranty, buy HP has made getting service somewhat difficult. Mostly in power supplies that have failed, but in a couple cases we have used a power supply from a switch with a failed mainboard to bring a switch with a failed power supply back to life. We do have UPS devices on all but three of four switches now, but that was not the case when I started two and a half years ago. Severe budget constraints (we were on the Dept. of Ed's financially challenged institutions list a couple years back) have forced me to look to the likes of Netgear and TrendNet for replacements, but so far these low-end models seem to be holding their own. It's also worth mentioning that the big change on our network this summer was migrating from a single cross-campus wireless SSID to the zoned approach mentioned earlier. I don't think this is the source of the issue, as like I've said: we've seen this before. However, it's possible this is exacerbating the issue, and may be much of the reason it's been so hard to isolate. Diagnosis At first it seemed clear to us, given the timing and persistent nature of the problem, that the source of the issue was an infected (or malicious) student machine doing ARP cache poisoning. However, repeated attempts to isolate the source have failed. Those attempts include numerous wireshark packet traces, and even taking entire buildings offline for brief periods. We have not been able even to find a smoking gun bad ARP entry. My current best guess is an overloaded or failing core switch, but I'm not sure on how to test for this, and the cost of replacing it blindly is steep. Again, any ideas appreciated.

• Establish direct cable connection between Windows 8 PCs in home network

  - by Marie. P.

  I'm running two PCs, a desktop and a laptop with Windows 8 Release Preview ("Build 8400"). They are connected to the same router in infrastructure mode, thereby having wireless internet. Due to often file synchronization between the machines I want to establish a cable connection that allows direct file transfer, without needing to use the wireless. When I plug in the cable (normal, not cross-over), I see in "Control Panel\Network and Internet\Network Connections": "Ethernet - unidentified Network" on both PCs. Transferring a file between both still only uses the WiFi via the Router. I noticed that when turning off the wifi on one PC, I can set up a shared internet connection that will work via Ethernet-cable, but since sometimes only one PC runs, sometimes the other one, I do not want to have the internet of one machine to be dependent on the other one being switched on. I do not have a crossover-cable, but since I did connect the PCs already successfully (just without both being on the internet), I'm sure that this should also work with a normal ethernet cable.

• Can GNU sed (for Windows) handle Unicode? If so, is it a code-page/locale issue, or a switch?

  - by Peter.O

  I've been using GNU SED on and off for a couple of years now. It spins me out a bit sometimes, but it does a good job... for single-byte char sets! I now and then notice references to GNU SED being Unicode-aware, but the closest I've seen of this is its "binary" mode.. and binary is not Unicode. Can GSED process a Unicode text file at CodePoint resolution, including and especially \r\n (Windows)... and if it can, does it expect UTF-8, UTF-16, or what? and how does SED detect the encoding?

• Trunking at Router Port

  - by singh

  After reading a bit about interVLAN routing got a doubt regarding how trunking takes place at router and at switch.In case of switch we configure a port interface as trunk port and say all vlan's are allowed here but in case of router we configure sub interface as trunk saying particular vlan belongs to particular subinterface .Can't we configure only a single port interface on router just like Switch and say all vlan's are allowed here on this interface ,why to go for sub interfaces? Hope I'm able to put my question in right way.

• Change ip route metric

  - by notphunny

  I'm constantly switching between eth0 and wlan0 interface on my archlinux because I often change OpenWrt fw images on my second router (which isn't connected anywhere). So I have problem with my routes when I'm connected to my wlan and want to connect with Ethernet to my router. Both routers are on 192.168.1.1/24 and after connecting to my Ethernet profile eth0 route becomes default one (which is ok for the time), because of smaller metric I guess. So I'm interested, how can I change routes metric so my applications can be connected to the internet (through out wlan)? Maybe there is solution not to use Default Gateway on Ethernet profile, however I still want to know how to change metric. Or default route if there are more then one.

• Locate devices within a building

  - by ams0

  The situation: Our company is spread between two floors in a building. Every employee has a laptop (macbook Air or MacbookPro) and an iPhone. We have static DHCP mappings and DNS resolution so every mobile gets a name like employeeiphone.example.com, every macbook air gets a employeelaptop.example.com and every macbook pro gets a employeelaptop.example.com on the Ethernet interface (the wifi gets a dynamic IP from a small range dedicated for the purpose). We know each and every MAC address of phones and laptops, since we do DHCP static mapping (ISC DHCP server runs on linux). At each floor we have a Netgear stack of two switches, connected via 10GB fiber to each other. No VLANs so far. At every floor there are 4 Airport Extreme making a single SSID network with WPA2 authentication. The request: Our CTO wants to know who is present at which floor. My solution (so far): Every switch contains an table listing MAC address and originating port. On each switch stack, all the MAC addresses coming from the other floor are listed as coming on port 48 (the fiber link). So I came up with: 1) Get the table from each switch via SNMP 2) Filter out the ones associated with port 48 3) Grep dhcpd.conf, removing all entries not *laptop and not *iphone 4) Match the two lists for each switch, output in JSON or XML 5) present the results on a dashboard for all to see I wrote it in bash with a lot of awk and sed, it kinda works but I always have for some reason stale entries in the switch lookup tables, making it unreliable; some people may have put their laptop to sleep, their iphones drop connections after a while, if not woken up and so on..I searched left and right, we are prepared to spend a little on the project too (RFIDs?), does anybody do something similar? I can provide with the script if needed (although it's really specific to our switches and naming scheme). Thanks! p.s. perhaps is this a question for stackoverflow? please move if it so.

• Binary data from a serial port in linux using c

  - by user1680393

  I am reading binary data from a serial port on Phidget sbc using Linux to get a command from an application running on a PC. I wrote a test program in VB to read the data into a byte array and convert it to decimal to use it but can’t figure out how to do it in c. I am unable to come up with anything with the research I have done on the internet. Command sent from PC is 0x0F. To check if I am getting correct data I read the data and send it back. Here is what I get back. Returned data has a carriage return added to it. Hex Display 0F00 0000 0D ‘\’ Display \0F\00\00\00\r Normal display just display a strange character. This tells me that the data is there that I can use, but can’t figure out to extract the value 0F or 15. How can I convert the incoming data to use it? I tried converting the received data using strtol, but it returns 0. I also tried setting the port to raw but it did not make any difference. unsigned char buffer1[1]; int ReadPort1() { int result; result = read(file1, &buffer1,1); if(result > 0) { WritePort1(buffer1); sprintf(tempstr, "Port1 data %s %d", buffer1, result); DisplayText(2,tempstr); } return result; } Port Open/Setup void OpenPort1() { //file1 = open("/dev/ttyUSB1", O_RDWR | O_NOCTTY | O_NONBLOCK); file1 = open("/dev/ttyUSB1", O_RDWR | O_NOCTTY | O_NODELAY); if(file1 < 0) printf("Error opening serial port1.\n"); else { SetPort(file1, 115200, 8, 1, 0, 1); port1open = 1; } } void SetPort(int fd, int Baud_Rate, int Data_Bits, int Stop_Bits, int Parity, int raw) { long BAUD; // derived baud rate from command line long DATABITS; long STOPBITS; long PARITYON; long PARITY; struct termios newtio; switch (Baud_Rate) { case 115200: BAUD = B115200; break; case 38400: BAUD = B38400; break; case 19200: BAUD = B19200; break; case 9600: BAUD = B9600; break; } //end of switch baud_rate switch (Data_Bits) { case 8: default: DATABITS = CS8; break; case 7: DATABITS = CS7; break; case 6: DATABITS = CS6; break; case 5: DATABITS = CS5; break; } //end of switch data_bits switch (Stop_Bits) { case 1: default: STOPBITS = 0; break; case 2: STOPBITS = CSTOPB; break; } //end of switch stop bits switch (Parity) { case 0: default: //none PARITYON = 0; PARITY = 0; break; case 1: //odd PARITYON = PARENB; PARITY = PARODD; break; case 2: //even PARITYON = PARENB; PARITY = 0; break; } //end of switch parity newtio.c_cflag = BAUD | DATABITS | STOPBITS | PARITYON | PARITY | CLOCAL | CREAD; newtio.c_iflag = IGNPAR; if(raw == 1) { newtio.c_oflag &= ~OPOST; newtio.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG); } else { newtio.c_lflag = 0; //ICANON; newtio.c_oflag = 0; } newtio.c_cc[VMIN]=1; newtio.c_cc[VTIME]=0; tcflush(fd, TCIFLUSH); tcsetattr(fd,TCSANOW,&newtio); }

• Wireless doesn't work on a Lenovo V570

  - by Stephen

  I've had Ubuntu installed on my HD for about 3 months but ever since I ran into this wireless issue I kinda lost my lust of Ubuntu. I have zero experience getting around with/ using the console command. I have a Lenovo V570. I got the driver update for the broadcom networking card via the Additional Drivers application but that did nothing. I love the look and feel of using Ubuntu but I have no technological experience for the matter. Any help would be awesome. When I scan for wireless connections while in Ubuntu, my computer picks up nothing, while on Win7 it will pick up the handful of wireless networks around my area. My wired connection is fine, but the use of not having wireless on a laptop is rather contradictory to it as a feature. Cheers! Also, I just installed 11.10, if that helps any. Yes, I used the search before I posted this, but again I have ZERO understanding of the command stuff and need a meat and potatoes answer(s). stephen@ubuntu:~$ sudo lshw -class network [sudo] password for stephen: *-network UNCLAIMED description: Network controller product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f1900000-f1903fff *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:04:00.0 logical name: eth0 version: 06 serial: f0:de:f1:63:98:14 size: 100Mbit/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=192.168.1.78 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s resources: irq:41 ioport:2000(size=256) memory:f1804000-f1804fff memory:f1800000-f1803fff stephen@ubuntu:~$ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no

• Wireless will not connect

  - by azz0r

  Hello, I have installed Ubuntu 10.10 on the same machine as my windows setup. However, it will not connect to my wireless network. It can see its there, it can attempt to connect, yet it will never connect. It will keep bringing up the password prompt everyso often. I have tried turning my security to WEP, I ended up turning it back to WPA2. It is set to AES (noted a few threads on google about that). Can you assist?

• Internet suddenly stopped working

  - by user95629

  I was using NoMachine to access Ubuntu 11.10 when suddenly the internet on Ubuntu stopped working. Now Ubuntu doesn't recognize the internet at all (including locally). Symptoms: Doesn't recognize the fact that there is an ethernet cable attached. (I've tried switching cables, didn't work.) GUI says "No network devices available" Can't ping external IP addresses. Tried changing /etc/network/interfaces to eth1 instead of eth0 but it didn't work. ifconfig provides no output relating to eth0. When I type "/etc/init.d/networking restart" it tells me "Cannot find device 'eth0'/Failed to bring up eth0." The network settings had used a static IP address prior to the crash. I don't know why it won't recognize the ethernet (I think this is the fundamental problem, but I might be wrong) and why it stopped working so suddenly--I haven't installed any updates lately. Any ideas? Any more information I should provide? EDIT: lspci recognizes the Ethernet controller; netstat does not. lspci calls it "Intel Corporation Device 0000"

• Delete eth0 avahi from the ifconfig list

  - by sai

  Hello this is the response I get from ifconfig. Now I have two eth0 things being showed up. I need to delete the second one which says eth0:avahi. I posted my ifconfig's response on a site as I has problem using wired internet, and they suggested to remove the eth0 avahi, to get internet. But I am a newbie to linux networking and have no idea how to delete this. response for ifconfig eth0 Link encap:Ethernet HWaddr 18:a9:05:22:cd:f9 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:28 Base address:0x4000 eth0:avahi Link encap:Ethernet HWaddr 18:a9:05:22:cd:f9 inet addr:169.254.10.43 Bcast:169.254.255.255 Mask:255.255.0.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 Interrupt:28 Base address:0x4000 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:796 errors:0 dropped:0 overruns:0 frame:0 TX packets:796 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:64016 (64.0 KB) TX bytes:64016 (64.0 KB) wlan0 Link encap:Ethernet HWaddr 00:26:82:3c:ac:27 inet6 addr: fe80::226:82ff:fe3c:ac27/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:52142 errors:0 dropped:0 overruns:0 frame:0 TX packets:30404 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:60816983 (60.8 MB) TX bytes:4160159 (4.1 MB)

• WPA2 authentication fails on Ubuntu 12.04 using Rosewill RNX-N1

  - by user94156

  Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. RNX-X1 works on other systems (including TV); also have 2 of 'em and tried each. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

• WPA2 authentication fails using USB network devices (Linksys and Rosewill)

  - by Greg Youtz

  Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. Tried the same with a Linksys USB network adapter. Both failed to authenticate. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

• Gnome-Network-Manager Config File Migration

  - by Jorge

  I think I have an issue with gnome-network-manager, I used to have a lot of connections configured, Wireless, Wired and VPN. After upgrading to 12.04 (from 11.10) I lost every configuration. I realized that the configs that used to be saved in $HOME/.gconf/system/networking/connections now are being saved in /etc/NetworkManager/system-connections/. I don't know how to migrate my settings to the new config file format Can anybody help me? jorge@thinky:~$ sudo lshw -C network *-network description: Ethernet interface product: 82566MM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 logical name: eth0 version: 03 serial: 00:1f:e2:14:5a:9b capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=1.5.1-k firmware=0.3-0 latency=0 link=no multicast=yes port=twisted pair resources: irq:46 memory:fe000000-fe01ffff memory:fe025000-fe025fff ioport:1840(size=32) *-network description: Wireless interface product: PRO/Wireless 4965 AG or AGN [Kedron] Network Connection vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 61 serial: 00:21:5c:32:c2:e5 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwl4965 driverversion=3.2.0-23-generic-pae firmware=228.61.2.24 ip=192.168.2.103 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:47 memory:df3fe000-df3fffff jorge@thinky:~$ lsb_release -a No LSB modules are available.

• How do I get a rt2800usb wireless device working?

  - by Jii

  My brand new desktop running 13.04 has endless problems with wireless. Dozens of others are flooding forums with reports of the same problems. It worked fine for a few days, then there were a few days where it started having problems sometimes and working sometimes. Now it never works at all. I have 5+ devices all able to connect without any trouble at all, including iPhone, Android phone, 3DS, multiple game consoles, a laptop running windows 7, and even a second desktop machine running Ubuntu 12.04 sitting right behind the 13.04 machine. All other devices have full wireless bars displayed (strong signals). At any moment, one of the following is happening, and it changes randomly: Trying to connect forever, but never establishing a connection. Wireless icon constantly animating. Finds no wireless networks at all. (There are 12+ in range according to other devices.) Will not try to connect to the network. If I use the icon to connect, it will display "Disconnected" within a few seconds. Will continuously ask for the network password. Typing it in correctly does not help. Wireless is working fine. This happens sometimes. It can work for days at a time, or only 10 mins at a time. Various things that usually do nothing but sometimes fix the problem: Reboot. This has the best chance of helping, but it usually takes 5+ times. Disable/re-enable Wi-Fi using the wireless icon. Disable/re-enable Networking using the wireless icon. Use the icon to try and connect to a network (if found). Use the icon to open Edit Connections and delete my connection info, causing it to be recreated (once it's actually found again). Various things that seem to make no difference: Changing between using Linux headers in grub at bootup, between 3.10.0, 3.9.0, or 3.8.0. Move the wireless router very close to the desktop. Running sudo rfkill unblock all (I dunno what this is supposed to do.) I've used Ubuntu for 6 years and I've never had a problem with networking. Now I'm spending all my time reading through endless problem reports and trying all the answers. None of them have helped. I am doing this instead of getting work done, which is defeating the whole purpose of using Ubuntu. It's heartbreaking to be honest.

It said to install gksu. I tried that, but of course, not having Internet, I didn't get the package. So instead I did: sudo gedit /etc/pm/power.d/wireless Which created the file. Here is the body: #!/bin/sh /sbin/iwconfig wlan0 power off I then rebooted. No change. I tried adding exit 0 to the bottom of the wireless file, and rebooted. No change. Please note that this is a desktop machine. I'm assuming power management is primarily for laptops, but the iwconfig does state that power management is on, so who knows. The recommended router changes I did not do, since the current router settings are (I think) required for some of the older devices I have, and because the current settings work on all my modern devices including Ubuntu 12.04 and Windows 7. I do appreciate the advice though, and I'll look into it when I have time. Anything else to try? Update #2 I booted into Ubuntu 12.04.3 from a dvd, and the same problems exist. I have a separate old desktop machine with 12.04 installed that has no wireless problems at all. So obviously the problem is wireless hardware compatibility in both 12.04.03 LTS and 13.04. Update #3 The same problems exist even when using a wired connection. I plugged an ethernet cable directly to the router and the network manager added an "Auto Ethernet" entry, but it cannot establish a connection to it. So the problem is not specific to wireless. Meanwhile, I purchased a Trendnet N300 wireless USB adapter, TEW-664UB. I plugged it in, but I have no idea how to get Ubuntu to try and use it. Can anyone tell me how? Can I download a package on another computer and copy the .deb over to do an install, etc? I'm installing windows 7 to double check that the internet connection works there and it's not just some magically faulty hardware. Thanks for your help.

• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

  - by oyse

  I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card. I know I can manually download the drivers directly from Asus, but I would rather not go that route. If there are anyone that knows about any packages or other things I can do to make this work would be much appreciated. Some systems details: $ lsb_release -a No LSB modules are available.

• Wifi - wireless network not working after installing Ubuntu 12.04

  - by Nilesh

  I had installed ubuntu 12.04 in my Dell Vostro 3460. Initially wired as well wireless both are not working. After installing compat-wireless-2012-07-03-pc.tar.bz2 wired network fine but wireless is not working. Previously both were working fine with ubuntu 11.10. Also presently both network are working fine in Win7. lspci: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Ivy Bridge PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.4 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 5 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 0de9 (rev a1) 02:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01) 03:00.0 Ethernet controller: Atheros Communications Inc.

• Wireless doesn't work after installing 11.10

  - by Ingram

  I just did a fresh install of 11.10 32 bit and I can't get my wireless to work. I installed the drivers the Broadcom STA wireless drivers through additional drivers and rebooted, but it still doesn't see any wireless networks Did something change in 11.10 that makes the wireless card not work anymore? I was using 10.10 before, and it worked fine. Do I need to go back to 10.10? sudo lshw -C network [sudo] password for user1: *-network description: Ethernet interface product: NetLink BCM5784M Gigabit Ethernet PCIe vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 10 serial: 00:1f:16:be:55:ff size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 duplex=full firmware=sb v2.19 ip=192.168.0.70 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:43 memory:f0300000-f030ffff *-network UNCLAIMED description: Network controller product: BCM4311 802.11b/g WLAN vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:09:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f0400000-f0403fff

• Disable discrete AMD GPU

  - by Smajl

  My notebook has two graphic cards and it suffers from severe overheating after installing Ubuntu (no problem with Windows 7 on the same machine). I figured out that the problem may be in the graphic card and I would like to disable the discrete one. I followed some tutorials on this topic (for example http://planetoss.com/articles/how-to-disable-the-discrete-amd-graphics-card-in-linux/). But the problem is, that after executing the commands, nothing really happens and both GPU are still running. Here is what I have done: smajl@smajl-mini:~$ sudo chown smajl /sys/kernel/debug/vgaswitcheroo/switchsmajl@smajl-mini:~$ echo IGD > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 smajl@smajl-mini:~$ echo OFF > /sys/kernel/debug/vgaswitcheroo/switch smajl@smajl-mini:~$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch 0:IGD:+:DynPwr:0000:01:05.0 1:DIS-Audio: :Pwr:0000:02:00.1 2:DIS: :DynPwr:0000:02:00.0 What am I missing here? Also, more on the overheating topic: 1) Installed TLP 2) updated system 3) set power setting mode to "power save" ...and nothing helps Tried same thing with Linux Mint without success. Is there anything else to try if I manage to disable the second GPU and the problem preserves? Otherwise I would have to get back to win in order not to melt my laptop.. :-/

• Lost WiFi after 12.10 upgrade

  - by Steven Guillory

  I received my new Dell Vostro 2420 last week, and just got around to upgrading from 11.10 to 12.10. Unfortunately, like many others (after researching the issue), I no longer have WiFi. I have tried every sudo command given that worked for others, and still can't get my wireless to function. I am new to Linux, so any and all help is appreciated. Thanks in advance! Edit: I can connect via ethernet, just not via wifi. As a matter of fact, when I use Fn + F2 to turn on wifi, only my bluetooth comes on. lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.3 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 4 (rev c4) 00:1c.5 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 6 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 07:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01) 09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
