There are two basic types of Wireless Routers: Linksys wireless G and Belkin wireless G. Both these devices perform similarly. They allow users to connect to both G and B networks as well as wired Ethernet gadgets to be linked to them. Apart from these basic features, the G routers facilitate all computers on a typical network to share internet connection.
The other router is the Linksys wireless B router, which splits the internet connection if the DSL modem is connected to the router. In effect every computer in the network gets an equal share of the internet bandwidth to which the router is accessing and allows parallel internet access among all the computers.
