    Question New to Linux/Ubuntu, trying to get my wlan to work


    Hi,

    After many years stuck with Windows, I've decided to give Linux a go. I've just installed Ubuntu 8.10 and everything works fine except I can't get my wlan to work properly.
    I'm runnig Linux on a new Acer TravelMate laptop with an Atheros AR5B91 chipset.
    Is there any easy way to get the proper drivers installed and make it work?
    The wlan is using WPA2 and AES. Does that present a problem?
    Would the above be easier on a 64-bit Ubuntu?

    A lot of questions from a newcomer, I know, but I'm grateful for all the help I can get! Apart from the wireless problem I'm finding Ubuntu and Linux really user friendly.

    All the best,
    Surfer

    Hi jayd512!

    Thanks for the tip. I have gone throough the advice in your link, which has shed some light on the problem. The Atheros chipset is found, but denoted as an "unknown device". My interpretation is that it means working drivers are missing. Correct?
    I've checked out Atheros homepage, without much luck so far. Do they only have drivers for Winows and if so why?

    Regards from surfer

    Hi D-Cat!

    Checked out your link as well. It contains a lot of info! I tried the backports-link and installed some packages usin Synaptic. So far so good. Unfortunately I couldn't find any ath5k module in any of the packages.
    With everything else working so smoothly in Linux, I'm surprised by the hazzle with getting a WLAN connection to work....

    All the best,
    surfer

    Did a search for 168C:002A

    Ahh. Apparently, your card uses the module ath9k ...

    I found some info here:
    Ubuntu Forums - View Single Post - [all variants] ath9k

    Ubuntu does not include the open source ath5k and ath9k drivers in their kernel. Apparently they consider them to be "experimental". They use the Madwifi drivers instead, and they would be installed afterwards, as they are not installed by default. It may not support all Atheros wireless chips, though.

    If you want to use the ath9k driver, a good source is to just install the latest compat-wireless package.
