with its internal, 4-port 10/100 switch, the model rp114 router can connect to either a 10 mbps standard ethernet network or a 100 mbps fast ethernet network. the local lan interface is autosensing and is capable of full-duplex or half-duplex operation. in addition, the lan interface ports automatically sense whether a connection is a normal or uplink connection, eliminating the need for uplink switches or crossover cables.
