Basic Setup Checklist
The following items are the most common errors made when initially setting up a router. Carefully
review the checklist to make sure that you have followed the recommended procedures.
Be sure to always start your network in this sequence:
1. Turn off and unplug the modem from its power outlet, and turn off the N600 wireless gigabit
router and computer.
2. Turn on the modem, and wait 2 minutes.
3. Turn on the N600 wireless gigabit router, and wait 1 minute.
4. Turn on the computer.
Make sure that the Ethernet cables are securely plugged in:
1. Verify that the Internet status light on the N600 wireless gigabit router is lit if the Ethernet
cable to the N600 wireless gigabit router from the modem is plugged in securely and the
modem and N600 wireless gigabit router are both turned on (see “Front Panel” on page 3).
2. Verify that for each powered-on computer connected to the N600 wireless gigabit router with
a securely plugged in Ethernet cable, the corresponding N600 wireless gigabit router LAN
port status light is lit (see “Front Panel” on page 3). The label on the bottom of the N600
wireless gigabit router identifies the number of each LAN port (see “Router Label” on page 6).
