I have a PC in my bedroom which is connected to a Belkin wireless router. Also attached to the router is a DSL modem which supplies the internet. I want to set another router up down stairs so I can plug my Xbox 360 & a second Pc in. I’ve tried wireless but the signal is too weak for streaming videos. Could I just plug another Belkin router into the one upstairs to link it all together or will I have to re-configure the routers in any way?
