While i was messing around inside the case, the network controller got pulled out of its slot. So I pushed it back in. When I restared the computer I get a message saying "digital line detection has stopped working" and a prompt that tells me I have to install software for my new device(the network controller). I'm assuming the network controller isnt working because of this. Where can I find this software? I put in my drivers cd, and tried downloading one of the dell webpage, but that wasnt it either. Here is my pc manual. http://support.dell.com/support/edocs/systems/inspd531/en/OM/appendix.htm#wp1123070 It's a wireles connection by the way.
