DESC: The Linksys Instant Broadband EtherFast Cable/DSL Router is the perfect option to connect a small group of PCs to a high-speed Broadband Internet connection or to an Ethernet back-bone. Configurable as a DHCP server, the EtherFast Cable/DSL Router acts as the only externally recognized Internet device on your local area network (LAN). The router can also be configured to block internal users' access to the Internet. Unlike a typical router which can only share 100Mbps over all its connections, the Linksys EtherFast Cable/DSL Router is equipped with a blazing 4-port EtherFast Switch, dedicating a breakneck 100Mbps to each and every connected PC.
