my sister just bought a laptop and seems to think she has to have wireless in the house. ive got 3 systems here that are wired, and i refuse to go wireless in any of them. so, what are my options? i need either a wired/wireless combo router or some way to splice a single connection into two routers. or.... is it possible to use the 4th open spot on my current router, plug it into a regular wireless router and supply its connection that way?
