    10.04 64bit on dektopPC - wireless problem

    My desktop PC's wireless card seems to be having trouble with Linux. I've tried openSUSE 12.1 and Fedora 16 and they all gave me the same problem. (Here's the thead I opened in Fedora forums http://forums.fedoraforum.org/showth...13#post1539313)
    Now, I'm back on Ubuntu 10.04 and I've gotta say it works better than it did on other distros but still, the problem persists. My PC specs are as follows.

    Code:
    Motherboard -- Asrock N68-S3 UCC
    CPU -- AMD Phenom 2 X4 AM3 3.3 GHz
    GPU -- MSI ATI Radeon HD 5450 1GB
    RAM -- 8GB DDR3 1333
    HDD -- 750GB SATA2 7200RPM, 80GB IDE 7200RPM
    PCI Wireless card -- TP-LINK TL-WN851ND (Atheros AR9287 chipset)
    I've searched on Google and Ubuntu forums for AR9287 related problems and found a few threads but none of them are on Ubuntu 10.04. Besides, I want more of a "direct help" so I decided to open my own thread.

    I've installed and tried Ubuntu 11.10 and the moment it got connected to my home wireless connection, it froze. Then, I went on trying other distros like I mentioned above (because I was quite put off by 11.10's interface and unity) but more or less encountered the same problem. So, now I'm back to home; Ubuntu 10.04

    Lucid seems to handle the wireless connection quite well.
    I tried the live CD first and then installed while connected to the wireless connection but hung up at 76%. So, I had to try it again but without being connected to the wireless.
    (I didn't mind this because it's the same on my laptop; not being able to install Ubuntu when connected to the Internet. My laptop uses ath9k driver as well but has been running 10.04 for ages without any trouble.)

    The installation was successful. I logged into the system for first time and connected to the home wireless connection. It was fine,...no freezing or hungups. I even ran Update Manager to download and install all the updates. Everything went well.

    However, the problem started when I tried to install apps from Synaptics. The PC completely freezes and I had to hold down power button to shut it down. I did this twice and it gave me the same problem.

    So, this is it...my tedious wireless problem. Is there solutions for this? Anything to make Ubuntu runs smoothly like it used to my laptop.

    If you need any further information from me, please let me know but do elaborate on technical details. Although I've been using Ubuntu for some time, I'm still not that technical savvy.

    Many thanks and regards.

    Hi,

    do you have a wired connectio available for updating? You should update the driver also via the backports-modules:

    Code:
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get dist-upgrade
    sudo apt-get install linux-backports-modules-wireless-lucid-generic
    and reboot.

    Thanks for the reply. No, I don't have a wired connection but I managed to run these commands using wireless.

    The first time I tried to run'em, I only got to "dist-upgrade". My PC was frozen when trying to install the backports.
    So, I rebooted and tried again, and it worked. Then, I went on running the software update; no updates available and it was working fine. Afterwards, I went into synaptics to install a bunch of apps I wanted. Again, everything seemed to be fine, no freezing.

    After all of that, I added Firefox-stable repo and tried to upgrade it from Synaptics but it got frozen. As usual, I rebooted to try again and it worked.

    To sum it all, my PC seems to be working well with wi-fi. I can pretty much use the Internet. BUT I still don't trust it. I think it will get hung up every now and then.

    I really don't want this problem to persist. Is there anyway to ensure this won't happen again? I'm also concerned about possible regression when I upgrade Ubuntu in the future (as the new LTS may have different kernal version).

    Nevertheless, thank you for the reply Best regards.

    Sorry for replying late.
    I really don't think this is a VGA-related problem but I maybe wrong. The driver I installed is Ubuntu recommended one from Admin -> Hardware.
    Code:
    sudo fglrxinfo
    display: :0.0  screen: 0
    OpenGL vendor string: ATI Technologies Inc.
    OpenGL renderer string: ATI Radeon HD 5400 Series
    OpenGL version string: 3.2.9756 Compatibility Profile Context

           clock: 33MHz
           capabilities: pm pciexpress msi bus_master cap_list rom
           configuration: driver=fglrx_pci latency=0

    Btw, the wireless problem has tasken a turn for the worse. I was using Ubuntu this morning to get all the info but right after connected to the wireless, the PC hung up. As usual, I rebooted my PC and tried again but it was exactly the same.

    So, I immediately disconnected and unchecked 'auto connect' to the wireless connection and retrived all the info. The following is networking info.

    Code:
    sudo lshw -c network
      *-network               
           description: Wireless interface

           capabilities: pm bus_master cap_list ethernet physical wireless

           resources: irq:18 memory:fbef0000-fbefffff
    I've gotta say my PC is really acting up on Ubuntu: even without being connected to the wireless, it hung up after about 15 minutes. It's seriously annoying and makeing me lose will to use Linux
    Ever since I've bought this PC, I've been wanting to use Linux. Also tried different distros. I've been quite eager to get it installed and configured so I can actually start doing some work on it. But now, it just seems impossible...

    Anyway, many thanks and regards.

    You can try one of these boot parameters

    I'm afraid I don't quite understand what you meant and what's written on there, mate.

    First of all, would you care to elaborate what you think the problem is here?

    Secondly, is that page available in English? I want to be able to read so I can understand the background of a problem discussed there. I understand I could probably use Google translate (although I'm not sure how accurate it'd be) but I just wanna know if there is an English version.

    Many thanks and regards.

    EDIT: Nevermind,...I think I'll probably have to change wireless card in this case.
