I have installed Ubuntu 12.04-64 bit on my Lenovo IdeaPad laptop, and the wired Ethernet (LAN) connection doesn't work.
lspci -vv | grep Atheros command from the terminal shows me I have the AR8161 Gigabit Ethernet controller:
02:00.0 Ethernet controller: Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 08)
This looks like a new product whose drivers are not built into Ubuntu.
How do I install drivers to get the AR8161 working?
