Network cable unplugged but isn’t

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?

Please help.
