    brand new ACER with Atheros AR9285 wireless adptr not working on 11.04

    sorry if this has been posted before but I could not find any related topics.


    Has this problem been fixed for the AR9285 ?
    I just bought a brand new Acer Aspire AS5733Z-4445 Intel Pentium P6100(2.00GHz) 15.6" 3GB Memory 320GB HDD Intel HD Graphics Notebook
    installed the latest ubuntu 11.04.
    Nothing shows up in a wireless scan and if I enter my access point info in manually it doesnt work.
    also odd, sometimes iwlist scan returns info for wlan0 and sometimes it doesnt.
    here is some info from my laptop.

    Try sudo modprobe -r acer_wmi. if that works add it to /etc/modules

    amazing update.
    I have been seeing a bunch of people claiming they can connect but the connection is very unstable.
    I was wondering why I cant connect at all.?

    so i brought it into work and gave it to a friend. He got it to work.. I said how ?
    he did the same things I did.. checked rfkill list and blacklisted acer-wmi. ( i saw posts about that
    but ignored it since I dont have acer-wmi in a lsmod)
    but i didnt care . he got it to work !!!

    I brought it home... amazing. no connection...
    and then it hit me... sun of a beeatch !!! I went down stairs and got closer to the router.
    it connected instantly..
    but now I have the problem that others are having.. extremely poor speed and unstable connection..

    this worked for me .. seems ok so far.

    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

    now im mad..

    its extremely unstable and I can see the router from where I am.. !!!!
    take 2 steps foward and it will connect..
    the range is miserable !!
    so as far as im concerned its not usable and the problem still exists.
