Use twisted-pair cable to connect any of the four LAN ports on the Wireless Router to an Ethernet adapter on your PC. Otherwise, you can cascade any of the LAN ports on the Wireless Router to an Ethernet hub or switch, and then connect your PC or other network equipment to the hub or switch. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.
Warning: Do not plug a phone jack connector into any RJ-45 port. This may damage the Wireless Router. Instead, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
