Quick Tips

This section describes tips for troubleshooting some common problems.

Sequence to Restart Your Network

If you must restart your network, follow this sequence:
1. Turn off and unplug the modem.
2. Turn off the router.
3. Plug in the modem and turn it on. Wait two minutes.
4. Turn on the router and wait two minutes.

Check Ethernet Cable Connections

If your device does not power on, make sure that the Ethernet cables are securely plugged in. The Internet LED on
the router is lit if the Ethernet cable connecting the router and the modem is plugged in securely and the modem
and router are turned on. If one or more powered-on computers are connected to the router by an Ethernet cable,
the corresponding numbered router LAN port LEDs light.

WiFi Settings

Make sure that the WiFi settings in the computer and router match exactly. The WiFi network name (SSID) and WiFi
security settings of the router and WiFi computer must match exactly.
If you set up an access list on the Advanced Wireless Settings page, you must add each WiFi computer's MAC
address to the router's access list.

Network Settings

Make sure that the network settings of the computer are correct. Wired computers and computers that are connected
over WiFi must use network IP addresses on the same network as the router. The simplest way to do this is to
configure each computer to obtain an IP address automatically using DHCP.
Some service providers require you to use the MAC address of the computer initially registered on the account. You
can view the MAC address on the Attached Devices page.

Troubleshoot With the LEDs

By default, the router is set with standard LED settings. If you turned off the LEDs except the Power LED, you must
return the LEDs to their standard settings for troubleshooting. For information about controlling the LED settings,
