I have this crappy Encore router (ENRTR-104). I want to replace it with this Linksys WRT120N ( http://www.linksysbycisco.com/EU/es/products/WRT120N ). I know nothing about routers, is this Linksys any good? for gaming and downloading stuff There will be 3 PCs and a PS3 connected to the router. I won't use WiFi, only cables. And is the only router in the F****** store!!! Thanks!!!
