My friend doesn't have internet at his house, so he uses a Netgear USB thing to connect to wi-fi signals near his house. Obviously the signal is very slow, so he says he wants a repeater but can't find one in any stores. I've looked on newegg for him and there are repeater hubs. How would you set up the repeater, and do you need a repeater cable. Or is the repeater cable a USB thing that would extend his signal by a bit. And is there anything else you'd need to know about repeaters/setting them up? Thanks.
