Troubleshooting with the LEDs
After you turn on power to the modem router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED
is on.
2. After approximately 10 seconds, verify that:
•
The Power LED is green.
•
The LAN port LEDs are lit for any local ports that are connected. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10
Mbps, the LED will be amber.
•
The ADSL link LED is lit, indicating that a link has been established to the connected
device.
Make sure that the Ethernet cables are
securely plugged in.
For each powered-on computer connected to the modem
router by an Ethernet cable, the corresponding numbered
router LAN port LED is on.
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 modem
routerand wireless computer must match exactly.
• If you set up an Access List in the Advanced Wireless
Settings screen, you must add each wireless computer’s
MAC address to the modem router’s access list.
Make sure that the network settings of the
computer are correct.
• Wired and wirelessly connected computers must have
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. Click the
link to the online document
, or see the documentation that came with your
computer.
• Some cable modem service providers require you to use the
MAC address of the computer initially registered on the
account. You can view the MAC address in the Attached
Devices screen.
Check the Test LED to verify correct
modem router operation.
If the Test LED does not turn off within 2 minutes after you turn
the modem router on, reset the router according to the
instructions in
“Using the Restore Factory Settings Button” on
Table 7-1. Quick Tips (continued)
