PLEASE HELP!!!!!!!!! If you have a modem with a built in router, you can use it as a wireless (wifi) router. Wifi doesn't cost money as a service. You just need the devices that are compatible with it. Wifi is just a different way of connecting stuff to the internet.
It's not the router that has the ports, it's the computer. A computer has 65,536 TCP ports and 65,536 UDP ports. And no, the number of ethernet slots on your router doesn't affect it. You should have four wireless ports and four Lan ports in your router as far as I understand. Source(s): my own router.
