I have an Acer with Atheros wireless adapter 9485. Originally when I installed Ubuntu 12.04 I had to turn off hardware encryption so wireless adapter worked then it work fine. However my Kodak 6100 didn't work with scanner so I upgraded to 12.10 and scanner worked. Now I can't get out to the internet using Firefox or Chrome. Using both wire and wireless I can connect but both browsers don't work. tried turning off encryption again but doesn't work.
I tried alot of things suggested in forums to no avail. Frustrated. Fairly new to command line but have some computer skills. Any ideas?
