you can change the remote management Web interface to a custom port by entering that
number in the box provided. Choose a number between 1024 and 65535, but do not use the
number of any common service port. The default is 8080, which is a common alternate for
HTTP.

Power LED Not On
If the Power and other LEDs are off when your gateway is turned on:
•
Make sure that the power cord is properly connected to your gateway and that the power
supply adapter is properly connected to a functioning power outlet.
•
Check that you are using the 12VDC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
All LEDs Stay On
If All LEDs stay on when your gateway is turned on:
•
Clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to
192.168.0.1. This procedure is explained in
“Erasing Configuration” on page 6-7
.
If the error persists, you might have a hardware problem and should contact technical support.
Local Link LEDs Not On
If the Local Port Link LEDs do not light when the Ethernet connection is made, check the
following:
•
Make sure that the Ethernet cable connections are secure at the gateway and at the hub or PC.
•
Make sure that power is turned on to the connected hub or PC.
•
Be sure you are using the correct cable:
—
When connecting the gateway’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.
Cable Link LED Not On
If the Cable Link LED does not light when connected to your cable television cable, check the
following:
•
Make sure that the coaxial cable connections are secure at the gateway and at the wall jack.
•
Make sure that your cable internet service has been provisioned by your cable service
provider. Your provider should verify that the signal quality is good enough for cable modem
service.

•
Remove any excessive splitters you may have on your cable line. It may be necessary to run a
“home run” back to the point where the cable enters your home.
Troubleshooting the Web Configuration Interface
If you are unable to access the gateway’s Web Configuration interface from a PC on your local
network, check the following:
•
Check the Ethernet connection between the PC and the gateway as described in the previous
section.
•
Make sure your PC’s IP address is on the same subnet as the gateway. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.0.10 to
192.168.0.254. Refer to
“Verifying TCP/IP Properties” on page C-6
or
“Configuring the
Macintosh for TCP/IP Networking” on page C-17
to find your PC’s IP address. Follow the
instructions in
Appendix C
to configure your PC.
Note:
If your PC’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign an IP address if the computer
cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If
your IP address is in this range, check the connection from the PC to the gateway and reboot your
PC.
•
If your gateway’s IP address has been changed and you don’t know the current IP address,
clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to
192.168.0.1. This procedure is explained in
“Erasing Configuration” on page 6-7
.
•
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
Make sure you are using the correct login information. The factory default login name is
admin
and the password is
password
. Make sure that CAPS LOCK is off when entering this
information.
If the gateway does not save changes you have made in the Web Configuration Interface, check the
following:
•
When entering configuration settings, be sure to click the APPLY button before moving to
another menu or tab, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
