Routers allow the transfer of data between networks. To properly display a network's connectivity, the router must support SNMP. LANsurveyor represents a router by displaying a custom icon with lines drawn to the networks to which the router is directly connected.

If a router's type cannot be determined or no icon is available, a generic router icon is used. You can manually assign a more meaningful icon and name to the router by using the Node Properties item in the Edit menu.
