Ubuntu 12.04 Not Detecting Ethernet Wired Connection

Question

I recently did a full install of Ubuntu 12.04 (not a dual boot) on my laptop. In the past on my dual boot, I connected to a wired ethernet connection with no trouble at all.

Now, my laptop isn't detecting a wired connection when the cable is plugged in. I've tried restarting things and tinkering with files as suggested by other answers with no success.

lspci | egrep -i --color 'network|ethernet'

02:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01)

First thing to acknowledge here is there are reports about your specific network card being working out of the box since the Ubuntu 13.04 release. You could upgrade to 13.10 now or if you prefer, install a more recent kernel using the LTS Enablement Stack. This installs a more recent kernel (and thus more hardware support) as well as a more recent Xorg graphical stack. The latter is not really of interest, but it does provide a fairly easy way to get more hardware support without upgrading to a more recent Ubuntu release.
