AOk so I have a wireless router in my house, and I get a wireless connection on a PC away from the router. But, I never have a good connection for gaming because the signal has to pass through so many reflective surfaces. So, my question is, can I buy a second wireless router, plug it into my PC and just get a better signal? Becuase I've tried all types of hi gain antennas/etc. Or, can I do the same thing with a new Modem?
