Atheros AR9285 / Lenovo G560 wireless not working after installing 13.04
- by teyi
I had Ubuntu 12.04 initially installed on my laptop. I upgraded to 12.10 then 13.04.
Everything worked fine, including wireless.
After adding a new memory card ( I only had 2 gb and one memory slot free) my wireess stopped working.
I backed up all my data and reinstallled Ubuntu 13.04.
Everything works fine except wireess.
I bought this laptop in 2010 from Japan.
It has Intel Core i5 CPU M 450 @2.40 Ghz * 4
3,7 Gb RAM
os type 64 bit
The output of iwconfig:
eth0 no wireless extensions.
lo no wireless extensions.

The wi-fi network appears as disconnected ( it's greyed out) Strangely enough I see a wifi network ( not mine) but not mine or the rest. That network doesn't require a password . I click on it, try to connect and i get an error message:
failed to connect to xxxxx ... 32) The access point/org/freedesktop/NetworkManager/AccessPoint/0
was not in the scan list.
Someone help please
