• Ubuntu 12.04, can't find my home wifi network

  - by Anton

• Wireless speed drops over time and doesn't get up if not reconnected

  - by Vili Lehto

  I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

• Integrating Azure ServiceBus and SharePoint 2010

  - by Sahil Malik

  SharePoint 2010 Training: more information My new article is finally online. I had been waiting for this for a while. The thing is, AppFabric became .NET 4, and left SharePoint 2010 behind. But fear not, we have REST API. But that brings up interesting challenges of how we can integrate Azure Service Bus with SharePoint 2010 (yes 2010, not vNext – I’m not giving NDA information out you fool), the design patterns you can use, figuring out challenging issues like security, sessions, and just app design patterns instead. Well, I hope you like my next article, SharePoint Applied: Azure ServiceBus and SharePoint 2010 Enjoy! Read full article ....

• sound stopped working after upgrade to 11.10 on Tuesday 20th March

  - by Hugh Barney

  My sound card stopped working after a set of updates were installed 2 days ago. The sound card is detected, the volume is not muted and the speakers work, I can make the speakers hum if I touch the jack plug lead that normally plugs into the card. hugh@lindisfarne:~$ lspci -v | grep -A7 -i "audio" 07:01.0 Multimedia audio controller: Creative Labs CA0106 Soundblaster Subsystem: Creative Labs SB0570 [SB Audigy SE] Flags: bus master, medium devsel, latency 32, IRQ 16 I/O ports at c000 [size=32] Capabilities: Kernel driver in use: CA0106 Kernel modules: snd-ca0106 I've tried reverting those upgraded packages that look like the could impact the kernal - but to no avail. alsamixer does not have anything muted, I've been though all the sound card debug/troubleshooting pages I can find. Kernal driver is attached. So whats gone pop ? I will boot from CD to check - but I am pretty sure this is a sw and not a hw problem.

• Ubuntu 14.04 Notification incorrectly displayed

  - by xenolyse

  I have a problem with my notifications on Ubuntu 14.04 x64. The notifications are just plain text with a colored background, and are also strangely placed in the top left corner. I have no idea on how it changed. After one reboot it was just there.. Here is a picture of the problem in question.: As you can see the notification appear over the unified menu. How can I restore the original state of the notification bubble? Here are the settings in ~/.notify-osd slot-allocation = fixed bubble-expire-timeout = 10sec bubble-vertical-gap = 5px bubble-horizontal-gap = 5px bubble-corner-radius = 37,5% bubble-icon-size = 30px bubble-gauge-size = 6px bubble-width = 240px bubble-background-color = 131313 bubble-background-opacity = 90% text-margin-size = 10px text-title-size = 100% text-title-weight = bold text-title-color = ffffff text-title-opacity = 100% text-body-size = 90% text-body-weight = normal text-body-color = eaeaea text-body-opacity = 100% text-shadow-opacity = 100% If I check the org.freedesktop.Notifications.service(/usr/share/dbus-1/servies) it appears to use the correct one.

• Periodic clicking sound from PC speaker

  - by John J. Camilleri

  After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

• Does not documenting code result in job security? [closed]

  - by Barry Brown

  Possible Duplicate: Should you write good documentation and clean code to increase the “Bus Factor”? I often ask young programmers why they are not documenting their code. Their responses, perhaps jokingly, frequently include "job security." I hear this from experienced professionals, too. And not just in programming; network engineers and system administrators widely subscribe to this belief. Can you really ensure job security by holding the details of your work in your head rather than on paper (or in files)? What's your experience?

• Timeout when trying to install ubuntu 12.04

  - by Oskars

  When i click on "try ubuntu" after booting it from a USB the screen goes black and a lot of text comes out. But after a while it says "timeout: killing /blablabalba" or something like and it just keep on saying that. What have I done wrong? <.< My computer is a Acer ASPIRE M5201 if that is of any importance. Edit: I noticed now that before it says "timeout" it says something about not supporting "DNS" or "Asn" or something like that. I'm not sure if it was exactly dns and asn but do this mean that I can't run ubuntu on this computer? Edit2: The exact strings are: "[sdg] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA " "timeout: killing '/sbin/modprobe -bv pci:v00001002d00"(and more nubmers wich I didn't catch)

• Bluetooth pairing works in 10.10 but not in 11.04

  - by Nathan Haines

  My laptop, a Compaq Presario V2000, has a built-in Bluetooth module that has worked well since at least Ubuntu 8.04 LTS. I use it to pair with headphones and a mouse. These both worked great in Ubuntu 10.10 (and still do with a live CD) but I cannot pair to any Bluetooth device in Ubuntu 11.04, even from a live CD. I can see the Bluetooth module in lspci and when I try to set up a new device from the Bluetooth indicator my computer detects all Bluetooth devices around me but pairing always fails. At the moment I'm most concerned with getting my Microsoft Wireless Notebook Presenter Mouse 8000 paired. Relevant output of lspci: Bus 003 Device 002: ID 03f0:011d Hewlett-Packard Integrated Bluetooth Module

• Menu bars are a basic light gray after installing graphics card driver. [closed]

  - by Jonathan

  Possible Duplicate: Desktop forgets theme? Hi, I've just installed Ubuntu 10.10 64-bit. It came up saying I could install 2 proprietary drivers, one for my WiFi adapter (which works perfectly) and one for my graphics card - a Sapphire AIT Radeon HD 5770 1024MB GDDR5 PCI-Express Graphics Card. The driver is called ATI/AMD proprietary FGLRX graphics driver. Before installing this driver I was unable to have Extra Visual Effects in Appearances. However after installing (and restarting) the menu bars are now in a basic light gray mode, rather than the sleek Ubuntu black. - Although Extra Visual Effects does now work. I've tried rebooting, and I've had a look around in ATI "Catalyst Control Center" but nothing has worked so far. Does anybody know what this windows mode is, how to change it back to normal and why it's doing it in the first place? Below is a screenshot of my computer: (This is also the first time I've installed Ubuntu on my computer, and am keen for it to work.)

• Wireless does not work anymore after software update with Ubuntu 12.10 on a Dell Latitude E6230

  - by Andy

  I just installed Ubuntu 12.10 on my DELL Latitude E6230, on first boot wifi worked properly but when I updated the software it stopped working. I can't figure out the problem... The wireless network controller is a Broadcom Corporation BCM4313 802.11b/g/n Wireless Lan Controller (rev 01) "lshw -class network" gives, for the above controller: *-network UNCLAIMED description: Network controller product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:02:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f7d00000-f7d03fff After reading the answer to another similar question, I edited the file NetworkManager.conf to make "managed=true", but that did not make any difference, it is as if the wireless adapter were not there. In the "Network" setting window, I only see "Wired" and "Network proxy". Wireless has just disappeared: rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no and that's it! Nothing about the wireless controller... Any suggestions?

• How to install Netgear N-300 UAB adapter WNA3100 on Ubuntu 12.04

  - by JacobusR

  After a fresh install of Ubuntu 12.04, the first thing I'm trying to do, is to setup my wireless adapter. I can see it using lsusb: beer@beer-linux:~$ lsusb ... Bus 002 Device 006: ID 0846:9020 NetGear, Inc. WNA3100(v1) Wireless-N 300 [Broadcom BCM43231] ... I have found a lot of dated instructions on the net and just wanted to know what the right way is to set it up on 12.04. I don't want to mess up a brand new install by tweaking things that don't need tweaking. According to most posts, you have to install the Windows drivers using the ndiswrapper package. Is this still the right way to go? If so, it would be great if someone could write down the steps to do this under 12.04

  I have updated yesterday to Ubuntu 12.04 but can not access the Internet. It is an old PC without wireless. But the older Ubuntu I had installed up until now (11.??) worked perfectly. I'm not that familiar with Ubuntu, and I have been trying Google for some time know, but I cannot find the answer. I noticed that running nm-tool resulted in some things that don't sound right: Type: wired Driver: ne2k-pci state: unavailable Default: no Carrier: off Does anyone have a way to fix the connection?

• How to keep a generic process unique?

  - by Steve Van Opstal

  I'm currently working on a project that makes connection between different banks which send us information on which that project replies. A part of that project configures the different protocols that are used (not every bank uses the same protocol), this runs on a separate server. These processes all have unique id's which are stored in a database. But to save time and money on configurations and new processes, we want to make a generic protocol that banks can use. Because of PCI requirements we have to make a separate process for every bank we connect to. But the generic process has only 1 unique identifier and therefor we cannot keep them apart. Giving every copy of that process a different identifier is as I see it impossible because they run entirely separate. So how do I keep my generic process unique?

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?
