at one point in 7.x there was a "feature" in the installer that if you did
not enable networking during the install, you ended up with an installed
system where networking was also not enabled.  that means you need to
find the appropriate incantation to turn on networking. Most likely,
right-click on the NetworkManager icon in the top panel, click "edit
connections", click  Ethernet in the window, then click the "Add" button,
and add to your heart's content.

you may need, subsequently, to right-click on the NM icon again then
"Enable Networking".

when "Add"ing, if you want the network you added to start at boot, on the
"General" tab of the add dialog, click "All users may connect to this
network". Otherwise it comes up when you log in, and down when you log
out. not what most of us want.
