Xbox Live problem, please read the description if you are good with tech stuff
I have an modem and a router upstairs, and my Xbox is downstairs. The wifi travels very badly in my house because it is very old and has a lot of walls so I do not get very good Xbox Live connection. I cannot run an ethernet cable all of the way up to the modem, and I can't move the modem and router downstairs, because then the computer would get hardly any wifi. Are there any ways to get a much better connection without running a cable all the way to the modem?
