Whats the cheapest way to set up a WiFi network? I already have a modem-router with 4 ports. 2 of the ports are used by PCs and 2 are empty. What should I buy? If I buy a WiFi router, I wouldnt really be plugging any computer to it. It's just for the WiFi.
What about this?

It's not a router. Will it work?
