    Angry Ubuntu 12.04 and Atheros AR9485 wireless

    Hi,

    I have ASUS Zenbook UX31e with Atheros AR9485 wireless adapter inside. I have a problems with wi-fi connection quality and stability. Signal level is too low (on Win7 was twice better) and Internet connection often disappears.

    At the same time another laptop with Win7 works with wi-fi perfectly: good signal level and stable internet connection.

    Can anyone help with this?

    Thanx!

    Thank you for help.

    Done. But signal level is still low (2-3 ticks) and internet connection sometimes disappears (at the same time wi-fi connected, but signal is 1 tick). On Win7 using this laptop I get 4-5 ticks...

    BTW router is really close to Zenbook...

    Any ideas?

    Sometimes it's 5 ticks..... Strange behavior
    BTW, if it's matter - power management for adapter is off.

    I think it may have something to do with this:

    Unhappy Re: Ubuntu 12.04 and Atheros AR9485 wireless

    I have the same problem -- my wifi on asus zenbook has too weak signal. Windows 7 is ok.

    I found no solution. The problem is still here on Fedora and openSUSE.

    hello gfmichaud. i have been searching around the web for a solution to this problem and you seem to have the right idea!

    the only problem is, that i don't quite understand what you're saying to do. I am running on Linux Mint and my kernel is Linux randy-UX31E 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
    Could you explain step 3 for a beginner?

    I too wanted to chime in and have been suffering with the Atheros wireless problem. My wireless worked fine in Windows but Linux it showed between 30% and 55% even when standing next to the router. Anyway, I stuck in a usb realtek wireless-n adapter;to test out that there was a problem with the Atherios card, and it worked perfectly fine

    So I did what the above poster said and it worked perfectly. I am now showing at 80% connection rate. a huge improvement.

    Just as @gfmichaud and @rrc326 say, do the following. it works great.


    The bug has been solved and the patches will be included in the next kernel (3.11 ?).

    It is possible to backport the fix to your current kernel :
    1) get the lateste archive here : https://www.kernel.org/pub/linux/ker...ts/2013/06/18/
    2) uncompress the archive and go in the uncompressed folder where mine was /home/"yourusername"/downloads/backports-20130618/
    3) go into a terminal in that last folder and type "make defconfig-ath9k", wait to finish, then type "make", wait to finish, and then type "sudo make install"
    4) you will be prompted to enter your password, do so, wait to finish
    5) reboot and enjoy the patched version of the driver

    I tried to explain as much of it as possible so, hope this helps....

    Hey rise99 I am fairly new to Ubuntu and I'm having trouble following your directions. I'm a noob and not ashamed to say it. I actually have two questions - 1. Is there a specific archive from the list I should get or does it matter which one - 2. How exactly do I go into the terminal in that last folder? Like I said I'm very new to Ubuntu and I am kinda having a rough time following some of the instructions on here (mainly because I'm kinda dense at times and I get confused as to what exactly I am being told to do lol). If you could clarify that would be greatly appreciated. Thank you for your time.

    The only important thing in the post above is 'solved in kernel 3.11'.

    Just do a clean install of 14.04 using wired internet access and you will get there.
