Quick Tips
This section describes tips for troubleshooting some common problems.

Sequence to Restart Your Network

Be sure to restart your network in this sequence:
1. Turn off and unplug the modem.
2. Turn off the router and computers.
3. Plug in the modem and turn it on. Wait 2 minutes.
4. Turn on the router and wait 2 minutes.
5. Turn on the computers.

Power L ED

Check the Power LED to verify correct router operation.
If the Power LED does not turn solid green within 2 minutes after you turn the router on, reset
the router according to the instructions in Factory Default Settings on page 119.

Check Ethernet Cable Connections

Make sure that the Ethernet cables are securely plugged in.
• The Internet LED on the router is on if the Ethernet cable connecting the wireless router
and the modem is plugged in securely and the modem and router are turned on.
• If a powered-on computer is connected to the router by an Ethernet cable, the LAN LED
is on.

Wireless Settings

Make sure that the wireless settings in the computer and router match exactly.
• For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the router and wireless computer need to match exactly.
• If you set up an access list in the Advanced Wireless Settings screen, you have to add
each wireless computer’s MAC address to the router’s access list.

Network Settings

Make sure that the network settings of the computer are correct.
