If the modem router does not save changes you have made in the Web Management 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.
Troubleshooting the Internet Connection
If your computer is connected to your modem router via a router, disconnect the router and directly
connect the computer to the modem router. If you now have Internet access, use the documentation
that came with the router to perform re-installation and troubleshooting.
If your modem router is unable to access the internet, but your Internet LED is green or blinking
green, you should determine whether the modem router is able to obtain an IP address from the
ISP. Unless you have been assigned a static IP address, your modem router must request an IP
address from the ISP. You can determine whether the request was successful using the browser
interface.
To check the WAN IP address from the browser interface:
1.
Launch your browser and select an external site such as
www.netgear.com
.
2.
Access the management interface of the modem router using your browser. For details, see
“Log in to the modem router.” on page 11
.
3.
Under the Maintenance heading, select
Modem Status
. Check that an IP address is shown for
the ADSL Port. If 0.0.0.0 is shown, your modem router has not obtained an IP address from
your ISP.
If your modem router is unable to obtain an IP address from the ISP, the problem may be one of the
following:
•
Your ISP may require a Multiplexing Method or Virtual Path Identifier/Virtual Channel
Identifier parameter.
Verify with your ISP the Multiplexing Method and parameter value, and update the router’s
ADSL settings accordingly.
•
If your ISP requires PPP over Ethernet (PPPoE) or PPP over ATM (PPPOA), check that your
login credentials are correct. See
“Troubleshooting PPPoE or PPPoA” on page 18
.

Troubleshooting
•
Log in to the modem router interface, note the modem router and ADSL status, run the
diagnostics test, and contact your ISP’s technical support representative. See the
User Manual
for detailed information.
Troubleshooting PPPoE or PPPoA
The PPPoA or PPPoA connection can be debugged as follows:
1.
Access the Main Menu of the router at
.
2.
Under the Maintenance heading, select the
Diagnostics
.
3.
Click
Run Diagnostic Tests
.
4.
If all of the steps indicate “OK” then your PPPoE or PPPoA connection is up and working.
If you cannot connect after several minutes, you may be using an incorrect Service Name, User
Name or Password. There also may be a provisioning problem with your ISP.
Troubleshooting Internet Browsing
If your modem router can obtain an IP address but your computer is unable to load any Web pages
from the Internet:
•
Your computer may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the modem router’s configuration,
reboot your computer and verify the DNS address as described in the online document that
you can access from
“Preparing Your Network” on page 23
. Alternatively, you can configure
your computer manually with DNS addresses, as explained in your operating system
documentation
.
•
Your computer may not have the modem router configured as its TCP/IP modem router.
•
If your computer obtains its information from the modem router by DHCP, reboot the
computer and verify the modem router address as described in the online document that you
can access from
“Preparing Your Network” on page 23
.
Unless you connect manually, the modem router will not authenticate using PPPoE or
PPPoA until data is transmitted to the network.

Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to
password
and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
•
Use the Erase function of the Web Management Interface.
•
Use the Default Reset button on the rear panel of the router. Use this method for cases when
the administration password or IP address is not known.
Using the Reset Button
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the Default Reset button on the rear panel of the router.
1.
Press and hold the default reset button until the Power LED turns red (about 10 seconds).
2.
Release the Default Reset button and wait for the router to reboot.
