Netgear DG834G series devices feature an integrated DSL modem, router, firewall and switch in one small network appliance. DG834G routers are designed to connect to and share a DSL Internet connection with multiple computers on the premises. With the factory default configuration, the DG834G automatically functions as a router when any device is connected to the Ethernet "LAN" ports. You can use a Netgear DG834G router as a switch by disabling the built-in DHCP server through the configuration interface.

With the DHCP server function turned off in the router, computers connected to the router's built in switch ports must receive their IP addressing information independently of the router, which makes the router function as a traditional switch.
