Help setting up wireless

So, after giving up on linux for a bit, I decided to try it again. I can’t seem to get wireless internet to work on my laptop. It’s a Toshiba Satelite, and the wireless driver that came with it is Atheros AR5007EG. Could someone help me go through the steps I need to go through to get wireless to work? I know hardly anything about linux.
