Wireless-G, the upcoming 54 Mbps wireless networking standard, is almost five times faster than the widely used Wireless-B (802.11b). And since Wireless-G devices share the same 2.4GHz radio band, they can interoperate with existing 11 Mbps Wireless-B equipment. A router lets you share a broadband internet connection with multiple computers by providing new independent Internet Protocol (IP) addresses for each computer connecting to the Internet. The wireless portion of the unit is an access point that enables the unit to perform the Ethernet networking functions wirelessly.
