Wi-fi modems play the role of modulating and demodulating wireless signals. Wifi routers are the devices which let you to connect with a wireless network, usually LAN, without any signal modulating and demodulating features.Wifi modems, do not care much about routing functions; they are just there to make signals completely readable.
