Wireless routers provide homes and small offices with the basic network infrastructure to connect two or more computers together. Routers facilitate wireless network packet routing and forwarding, and act as access points and internet routers for local area networks.
A wireless router uses radio networks to communicate to and within external network environments. Depending on its capacity, a wireless router can support up to hundreds of simultaneous computer users. Aside from Internet sharing, wireless routers can also be used for file sharing and printing. Alternatively, a crossover Ethernet cable can be used to directly connect two computers that do not have access to a shared network.
