Lately I got a DELL inspiron 15-3521, I installed the latest Linux mint cinnamon. I have been having some problems with my Ethernet card, when i start my pc everything works perfectly for about 10 to 30 minutes then I get disconnected from my wireless networking and I can't reconnect until I restart my PC. I tried disabling enabling my network but with no result. Any ideas why I keep getting disconnected?
My Ethernet card is:
Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
