You should go to the Linksys website for a complete tutorial. I had difficulty getting a wireless signal from one side of my house to the other, so what I did was get 2 routers, one for each side connected by a wire with the routing function disabled on the second router, turning it into a switch with wireless access point. I gave both routers the same SSID so my computer(s) could choose the one with the best signal depending on location. I tried a range expander but that made things worse, I think by creating reflections that were difficult to discern. Be mindful that any and all wireless devices share 1 port, whereas each wired device gets the port it's plugged into. So if you had 4 computers plugged in to ports 1-4 and a 4 computers wireless , each wired port gets 20% (1/5th) of the "signal" and each wireless computers gets 1/4 of the remaining 20% allotted to the wireless access. With my setup, I have 2 access points, so not as much competition for "air time".
