I have just installed Ubuntu 12.1O on my new Samsung NP350E7C-S05NL laptop. The problem is that it wireless internet keeps disconnecting, after a few minutes working, and I have to continuously restart the internet connection.

When I do lscpi -nn I get:

03:00.0 Network controller [0280]: Atheros Communications Inc. AR9485 Wireless Network Adapter [168c:0032] (rev 01)

Do you know how to solve this?
