I'm not exactly sure how to describe it, but no matter how many times I unplug and replug my network cable, my broadband router still registers that it's not connected. I've tried resetting the router, reinstalling both the broadband and the atheros wireless card on my laptop(but there doesn't seem to be anything wrong with that...), and, as said, replugging it. I'm kind of at a loss; I'm pretty computer savvy but can't really figure this out. My dad said he's going to rewire it to see if that works, but if it doesn't, does that just mean we need to get a new one?

I have had the same problem and spent days scouring Google and trying any suggestion that I could find. Last night I found a post from 2002. It seemed ridiculous but I gave it a shot. PROBLEM SOLVED.
1.) Shut dowm your PC.
2.) Unplug the power cord.
3.) If you have a laptop, remove the battery as well.
4.) Walk away from the problem for at least 30 minutes.
5.) When you return, reconnect battery and power cord.
5.) Start as usual.
6.) If this solves the problem, take 20 minutes and post this to all of those message boards that you didn't find the solution to.
I had the same issue on a Latitude D600 after reinstalling the OS. After many days of frustration I found that the issue is due to a duplex mismatch between the internet router and the 570x controller. The default setting on the controller is set to Auto but for some reason this causes the network cable not to be detected, after changing the setting to a specific speed and duplex like lets say 100 full duplex the cable was detected and the controller started working. If your are having this issue try playing around with the duplex settings on the controller.
