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.

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 router and the

modem is plugged in securely and the modem and router are turned on.

• For each powered-on computer connected to the router by an Ethernet cable, the

corresponding numbered router LAN port LED is on.

Hard Disk Drive (HDD)

If you turn off the router when an HDD is installed, wait 2 seconds before turning it back on to

give the HDD enough time to reset.

If the HDD LED is red and it used to be green, the HDD connection could be loose. Turn off

the router. Disconnect the HDD, and then connect it again. Turn on the router and check the

HDD LED.

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.
