Cable/dsl router with wired and wireless ethernet built in

Some broadband routers have both wired and wireless ethernet LAN connections.  In these routers, both networks are bridged together into a single network. The router also acts as a wireless access point for the wireless segment.  These routers are very versatile and like other broadband routers, they keep your local LAN traffic separate from your WAN internet traffic by acting as a firewall.
