Ubuntu: Atheros AR9485 wireless card doesn't work in an ASUS K53E


I just installed Ubuntu 11.10 32-bit version in dual boot mode on an ASUS K53. Every thing seems to work fine except for the wireless. The wireless works on Windows 7. Ubuntu finds the wireless card, but it does not appear to be turned on. The only physical means of turning on the card is the FN-F2 key combo. That works on Windows, but not in Ubuntu. I've looked in the forums for a solution and I'm not quite sure what to do. I've gathered the following information:

Any help would be appreciated. Thanks.


Solved! Installed linux-backports-modules-cw and network-manager update. Works well. linux-backports-modules-cw can be found in software center and network-manager update can be get via normal uodatin method. For anybody who needs this info in Tukish navigate to my blog entry : http://gkaya93.blogspot.com/2012/05/ubuntu-1204-wireless-cozumu.html . I will write an English description here:

  • Check the table in this page to see if your wireless card (or sth similar*) is there : http://wiki.ubuntuusers.de/WLAN/Linux-backports-modules#Enthaltene-Treiber
  • If there, do the following:
  • Go to terminal and enter "uname -r" for returning kernel version.
  • Search for a matching version of "linux-backports-modules-cw" in software center. Install it.
  • Update network-manager.
  • Reboot and see if it affects. It changed my experience a lot. It's really better now.

*My card was rtl8192se. It wasn't included in the table, instead, rtl8180/rtl8187. but the software healed my system. So go ahead and try if your card's model is close to included models. I guess this is safer than manipulating system configuration files.

And sth to include, on the website, it says that linux-backports-modules-cw is included in the Live image, so you can install if have no connection. I didn't try it, as I have formatted my live medium. But if you didn't, add it to your Software sources and try to use. - Software Center > Edit > Software sources > Installable from CD-ROM/DVD... Check the checkbox below it.

I guess this thing would work well in elderly Ubuntu versions, but I'm not sure and encouraging anyone to try it because of my word. Thanks for any support made.
