If you are in Unity or Gnome from a terminal write: sudo gedit /etc/modprobe.d/blacklist.conf. Then go to the bottom and add: blacklist acer_wmi. I hope the solution works for you because adding it did nothing for me but it is still worth a try. Roman

I googled the problem and found this link:

http://sage.bt/tips/get-atheros-ar242x-ar542x-wireless-card-to-work-on-ubuntu.html

Unfortunately when I input the command into the terminal I get this message:

bash: /etc/modprobe.d/blacklist.conf: Permission denied

I don't know of any alternative solutions, but advice is appreciated.

  sorry if i wasn't clear. my network control panel says that wireless is not available. i can't set the toggle to "on" for wireless (it just flips back immediately to off). there are wifi networks in my house, but since i can't turn wireless on, i can't log on to them.

  it does show a hardware address for the wireless, but says unavailable. when i grep the driver (ath5k) it seems to be there:ath5k 145100 0 ath 19387 1 ath5k mac80211 393421 1 ath5k cfg80211 172427 3 ath5k,ath,mac80211

  Kernel is updated.

  UPDATE: I found that under networks (upper right of desktop) when I pull it down that it says "wireless is disabled by hardware switch". So it looks like this is a hardware issue. I thought this was not broken, but it may be. If anyone knows of how Ubuntu could affect a hardware switch, let me know!

  Took out the wireless card and reseated card and two connections to it. After several reboots, I was able to suddenly enable wireless. Don't know why it took reboots, but I am now good to go. The switch still seems to flick to orange, but then goes blue again. All without me touching it. So probably hardware, Sorry to bother the hivemind.
