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 N300 wireless router
and computer.
2. Turn on the modem, and wait 2 minutes.
3. Turn on the N300 wireless 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 N300 wireless router is lit if the Ethernet cable to the
N300 wireless router from the modem is plugged in securely and the modem and N300
wireless router are both turned on (see “Front Panel” on page 3).
2. Verify that for each powered-on computer connected to the N300 wireless router with a
securely plugged in Ethernet cable, the corresponding N300 wireless router LAN port status
light is lit (see “Front Panel” on page 3). The label on the bottom of the N300 wireless router
identifies the number of each LAN port (see “Router Label” on page 5).
