Wireless Broadband Routers

These wireless routers for home networks employ 802.11g technology.

802.11g wireless broadband routers support higher speeds and more options than older 802.11brouters. If upgrading from 802.11b, you should notice faster file sharing and printing, and you can add more computers to an 802.11g network without bogging it down.

802.11g routers are not as fast or full-featured as newer 802.11n wireless routers. However, when you consider their solid performance, overall capabilities, and more affordable pricing, an 802.11g router may still be right for you.
