Help set up Atheros ar242x/ar542x wireless adapter
just did a clean install of 11.10 on a new SSD. and i can't turn on Wi-Fi. Used google and found a number of answers pointing towards interference with acer_wmi (here for instance). so i blacklisted that driver and rebooted. Still no go. I go to Wi-Fi and I can flip the switch to "on" but it is not orange and it snaps immediately back to off.
This is on a Compaq Presario CQ50. i note that it has an illuminated Wi-Fi button right next to the power button. pushing this has no effect, the light doesn't toggle. The Wi-Fi did work (under Windows) until the hard drive crashed.
Here is iwconfig
output:
pk@alot_of_ocelot:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bg ESSID:off/any

I am happy to post anything else, but as I too am a n00b at Ubuntu, not sure what would be useful.
