Some time ago I managed to get my networking to work:
http://ubuntuforums.org/showthread.php?t=2079627

I decided to upgrade my network to the N standard and everything works fine on windows, but ubuntu 12.10 fails to find my network. I connected an atheros based dongle which found my network and successfully connected to it.

At this point I was running the wl driver. I followed https://help.ubuntu.com/community/Br...%28Wireless%29 and installed sta drivers blacklisting b43 and wl. In dmesg I found this extra errors :
Code:
atkbd serio0: Unknown key pressed (translated set 2, code 0x93 on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e013 <keycode>' to make it known.
BCM continued to work the same way: N network not visible.


Thank You in advance.
