By saying "I don't want to pay Comcast to move the connection," I meant that they charge me $40 to go up into my attic and move the cable wire from the living room outlet to the cable outlet in my bedroom.
The problem with buying and using cables myself is that there's no way to make it so that the cable can't be seen- it'd either be going straight across my living room into my bedroom or have to be taped along the wall or ceiling or something. I'm really not going to try to put it under my carpet, either.
I have a Linksys WRT160N router, so basically all I need is the wireless card so my PC can have wireless capability.
Also, yeah I have Win7.
Looks like you guys are leaning towards D-Link. I guess I'll check it out, then.
