Well I'm posting from a friends computer, because I recently had to reinstall windows on to mine and afterwards I was missing a few drivers. The ones that matter most are for my Network controller and Ethernet controller. I think because of this, I dont have any network connections. If I turn my wireless card on, it just turns on but nothing happens, if I plug in a Ethernet cable nothing happens either, I don't even see the little green and orange lights I used to. So I come here looking for a solution to the problem if anyone knows of one. Thanks.
