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 WiFi DSL modem router and computers.
3.
Plug in the modem and turn it on. Wait 2 minutes.
4.
Turn on the WiFi DSL modem router. Wait 2 minutes.
5.
Turn on the computers.
Check Ethernet Cable Connections
Make sure that the Ethernet cables are securely plugged in:
•
The Internet status LED on the WiFi DSL modem router is lit if the Ethernet cable
connecting the WiFi DSL modem router and the modem is plugged in securely and the
modem and WiFi DSL modem router are turned on.
•
For each powered-on computer connected to the WiFi DSL modem router by an Ethernet
cable, the corresponding numbered router LAN port LED on the back of the WiFi DSL
modem router is lit.
Wireless Settings
Make sure that the wireless settings in the computer and WiFi DSL modem router match
exactly.
•
For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the WiFi DSL modem 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 WiFi DSL modem router’s access list.
Network Settings
Make sure that the network settings of the computer are correct:
•
Wired and wirelessly connected computers need to have network (IP) addresses on the
same network as the WiFi DSL modem router. The simplest way to achieve this address
commonality is to configure each computer to obtain an IP address automatically using
DHCP.

•
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.
Troubleshoot with the LEDs
After you turn on power to the WiFi DSL modem router, the following sequence of events
should occur:
1.
When power is first applied, verify that the Power LED is lit.
2.
Verify that the Power LED turns red within a few seconds, indicating that the self-test is
running.
3.
After approximately 30 seconds, verify the following:
•
The Power LED is solid green.
•
The Internet LED is lit.
•
The Ethernet LED is lit for any local port that is connected to a computer. This LED
indicates that a link has been established to the connected device.
The LEDs on the front panel of the WiFi DSL modem router can be used for troubleshooting.
Power LED Is Off or Blinking
•
Make sure that the power cord is securely connected to your WiFi DSL modem router and
that the power adapter is securely connected to a functioning power outlet.
•
Make sure that you are using the power adapter that NETGEAR supplied for this product.
•
If the Power LED blinks slowly and continuously, the WiFi DSL modem router firmware is
corrupted. This situation can happen if a firmware upgrade is interrupted, or if the WiFi
DSL modem router detects a problem with the firmware. If the error persists, you have a
hardware problem. For recovery instructions or help with a hardware problem, contact
technical support at
.
Power LED Stays Red
When the WiFi DSL modem router is turned on, the Power LED turns red for about 20
seconds and then turns green. If the LED does not turn green, the WiFi DSL modem router
has a problem.
If the Power LED is still red 1 minute after you turn on power to the WiFi DSL modem router:
1.
Turn off the power and back on to see if the WiFi DSL modem router recovers.
2.
Press and hold the
Reset
button to return the WiFi DSL modem router to its factory
settings.
See
Factory Settings
on page 153.

If the error persists, you might have a hardware problem and should contact technical
support at

.
LEDs Never Turn Off
When the WiFi DSL modem router is turned on, the LEDs light for about 10 seconds and then
turn off. If all the LEDs stay lit, a fault exists within the WiFi DSL modem router.
If all LEDs are still lit 1 minute after power-up:
•
Cycle the power to see if the WiFi DSL modem router recovers.
•
Press and hold the
Reset
button to return the WiFi DSL modem router to its factory
settings. See
Factory Settings
on page 153.
If the error persists, you might have a hardware problem and should contact technical
support at
www.netgear.com/support
.
Internet or Ethernet Port LEDs Are Off
If the Internet LED or the Ethernet port LEDs do not light when the Ethernet connection is
made, check the following:
•
Make sure that the Ethernet cable connections are secure at the WiFi DSL modem router
and at the modem or computer.
•
Make sure that power is turned on to the connected modem or computer.
•
Be sure that you are using the correct cable.
When connecting the WiFi DSL modem router’s Internet port to a cable or DSL modem,
use the cable that was supplied with the cable or DSL modem. This cable could be a
standard straight-through Ethernet cable or an Ethernet crossover cable.
Wireless LED Is Off
If the Wireless LED stays off, check to see if the WiFi On/Off button on the WiFi DSL modem
router has been pressed. This button turns the wireless radios in the WiFi DSL modem router
on and off. The Wireless LEDs are lit when the wireless radio is turned on.
The Push 'N' Connect (WPS) Button Does Not Work
If after you press the WPS button and the Wireless LED does not blink, check the following:
•
Make sure that you are using the button and not the WiFi DSL modem router’s built-in
registrar.
•
Check that PIN verification has succeeded for the wireless device you are adding to the
wireless network.
