    Atheros AR9285/Ubuntu 12.04/HP G6 1220sd

    Hello Ubuntu peeps.

    I bought a new laptop a few months ago and directly installed a linux system to dual-boot with W7.

    I now have a fresh install of Ubuntu 12.04 and it detects the WiFi card out of box. The range however is terrible, it detects maybe one connection, and most of the time it is not even my own. If I sit next to the router, it picks up my connection and I can connect, but as soon as I move two meters away, the connection drops.
    On W7, the card detects up to 15 available connections, but maybe 1 on Ubuntu.

    2.4 GHz Intel Core i5-2430M.

    Any suggestions?

    Hi,

    obviously its not a Ubuntu problem, if it occurs with several distros. Check, if the router firmware is up-to-date and/or if a MAC-filter is activated in your router interface.

    BTW: Try pure WPA2-AES (CCMP) encryption in your wifi, thats more stable and more secure.

    Re: Atheros AR9285/Ubuntu 12.04/HP G6 1220sd

    Thank you for your reply praseodym.

    I know this is not a Ubuntu problem, but a compatibility issue between linux distros and AR9285 - or in my case at least.

    However I don't think this has anything to do with the router settings, as it does not matter where I am. The same thing happens when I go over to a friend's house and try to connect over there.

    I was wondering if anyone knew of a solution/tweak that could solve this problem.

    Re: Atheros AR9285/Ubuntu 12.04/HP G6 1220sd

    The other distros also have kernel 3.x? Deactivate the hardware encryption of the driver, most of the time this helps:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k

    Thanks again for your swift replies praseodym.

    I disabled the hardware encryption, rebooted, but can still only see one WiFi connection.

    I have tried Ubuntu 10.04 and 12.04, Linux Mint 12 and 13, Fedora 16 and 17, and OpenSUSE 12.1. Most of them having kernel 3.x.

    Re: Atheros AR9285/Ubuntu 12.04/HP G6 1220sd

    Which channel do you use? Please show

    iwlist chan
    sudo iwlist scan
    rfkill list
    dmesg | grep country
    Tried a fixed channel, e.g. 1 or 6? Router-reset?

    Re: Atheros AR9285/Ubuntu 12.04/HP G6 1220sd

    One of these 2 networks is yours? Try channel 1 plus pure WPA2-AES encryption, mixed encryption (like shown here) causes troubles.

    For the number of channels:

    Code:
    sudo apt-get install iw
    iw reg get
    sudo iw reg set DE #DE for Germany, replace it with your country code
    iw reg get
    Check after all changes:

    Code:
    iwlist chan
    iwconfig
    cat /etc/resolv.conf
    route -n
    sudo iwlist scan
    Maybe strange charcters in the Key? How many letter-figure combinations does the key have? For WPA2-AES it should be at least 8
