High Speed Cable Modem
Use LEDs to Troubleshoot
The following table provides help when you are using the LEDs for troubleshooting.
Table 2. Troubleshooting with LEDs
LED Behavior Action
All LEDs are off when the cable
modem is plugged in.
• Make sure that the power cord is properly connected to your cable
modem and that the power supply adapter is properly connected to a
functioning power outlet.
• Check to see that you are using the 12 VDC, 2.5A power adapter from
NETGEAR for this product.
• If the error persists, a hardware problem occurred. Contact technical
support.
All LEDs stay on. • Clear the configuration of the cable modem to its factory defaults.
• If the error persists, a hardware problem occurred. Contact technical
support.
The Ethernet LED
is off and a
powered-on device is connected
to an Ethernet LAN port.
• Make sure that the Ethernet cable connections are secure at the cable
modem and at the computer, router, or WiFi router.
• Make sure that power is turned on to the connected hub or computer
.
• Be sure that you are using the correct cable.
The Internet LED is off and the
cable modem is connected to
the cable wall jack.
• Make sure that the coaxial cable connections are secure at the cable
modem and at the wall jack.
• Make sure that your cable Internet provider provisioned your cable
Internet service.
Your provider can verify that the signal quality is good
enough for cable modem service.
• Remove any extra splitters that you installed on your cable line. Run a
“home run” back to the point where the cable enters your home.
The Power LED lights red
. The cable modem is too warm and might overheat. Do the following:
1. Disconnect the power adapter
.
2. W
ait a couple of minutes to let the cable modem cool down.
3. Make sure that the cable modem is placed in a vertical position.
4. Make sure that the cable modem is placed in a location with good
ventilation.
5. Reconnect the power adapter
.
Troubleshooting

High Speed Cable Modem
Cannot Log In to the Cable Modem
If you cannot access the cable modem from computer that is connected to the cable modem
or to a router that is connected to the cable modem, check the following:
• If your computer is connected to the cable modem with an Ethernet cable, check the
connection.
• Make sure that your computer’s IP address is on the same subnet as the cable modem.
The IP address of your computer must be in the range of 192.168.100.2 to
192.168.100.254.
• Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are using
Internet Explorer, click the Refresh button to make sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The cable modem user name
admin is lowercase (Caps Lock is off). The default password is password.
If the cable modem does not save changes you made, do the following:
• When entering configuration settings, be sure to click the Apply button before moving to
another page, or your changes are lost.
• Click the Refresh or Reload button in the web browser. The changes occurred, but the
web browser might be caching the old configuration.
Troubleshoot the Cable Internet Connection
If your cable modem cannot access the Internet but the Internet LED lights green, make sure
that the cable MAC address or device MAC address of your cable modem is registered with
your cable Internet provider (see
