A wireless router, also called a WiFi router, combines the networking functions of a wireless access point and a router. Wireless routers are the hardware devices that Internet service providers use to connect you to their cable or xDSL Internet network. This determines the next network point to which a packet should be forwarded toward its destination. The WiFi router works in the same way as the router in a hard-wired home or business local area network but allows greater mobility for notebooks or portable computers. Wireless routers are by far the most popular way to connect to the internet in your home.
