Today I installed Ubuntu 11.10 x64 on to my lenovo B570 using wubi.exe. After booting up, I discovered that I could not turn on wireless networking. I have a Atheros AR9285 wireless card.
I ran through the Ubuntu wireless troubleshooting guide, and the output suggest that the card has a driver, but it simply wont turn on! (I will post this soon.)
linuxwireless.org seems to have an archive of drivers called compat-wireless which is purported to fix this issue, but I'm new to Linux and don't know how to install them.
LBM may also be an solution, but I'm having difficulty downloading and installing the package.
There have been several post about driver issues with this card before, but all of the solutions assume wired internet access, or I simply don't understand them.
Any help will be greatly appreciated!
What I've tried so far:
- Installed Linux Backport Modules today. Wifi is still not working.
- Installed compat-wireless. Wifi is still not working.

After some research, I'm fairly certain Atheros' ath9k driver is worthless, and needs to be replaced. Since I already tried this with LBM and compat-wireless, I will look for an older version of the ath9k driver. I'm not sure what MadWifi is but it warrants looking into as well. Also looking into turning off softblock.
Hasn't someone already fixed this issue?
