I have a 3.0Mbps/786Kbps cable connection in my apartment. I only have 1 cable connection comming into the house and my landlord won't let me get another so my computer si stuck on the same wall as my TV which I do not like. I wnt to put it in the same room just on the opposite wall, it would only be about 20 or so feet away with no restrictions. Is what I need a 802.11b router? If so what a few good ones?
