represents the WAN interface, the connection to the Internet. It is the physical link to the service
provider's network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10/100 BASE-
TX Ethernet port on the rear panel. Any connection to an Ethernet concentrating device such as a
switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any
Ethernet device that is capable of operating at speeds between 0~100Mbps, be sure that the
device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed
port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make
this connection. When connecting the Router directly to a PC or server use a normal straight-
through cable. You should use a crossed cable when connecting the Router to a normal (MDI-X)
port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-
II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the
cable connecting the LAN to the Router does not exceed 100 metres.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through
cable as shown in the diagram below:
If you wish to reserve the uplink port on
the switch or hub for another device,
connect to any on the other MDI-X ports
(1x, 2x, etc.) with a crossed cable.

You can connect the Router
directly to a 10/100BASE-TX
Ethernet adapter card (NIC)
installed on a PC using the
Ethernet cable provided as
shown in this diagram.
