Direct Connection: When you connect your wireless router to a single PC, connect
the Ethernet port on the network interface and power supply unit and the network
interface on your PC "crossover" Ethernet cable.
LAN Connection: When you connect your wireless router to multiple PCs via a hub,
router, or switch, use standard "straight-through" Ethernet cables throughout the entire
network.
Home PNA Connection: When you connect your wireless router to multiple PCs via
home PNA, use standard Ethernet cables between the network interface and power
supply unit' s home PNA connection and the RJ11 p hone jack. You can also connect
the cable directly to your PC' s home PNA adapter.
The router automatically activates the Ethernet or home PNA, depending upon which
connector is used. If a cable is connected to both connectors, the Ethernet port is
activated.
