Troubleshooting 6-5
4. If any of the steps indicates “Failed”, you can attempt to reconnect by clicking “Connect”. The
modem will continue to attempt to connect indefinitely.
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 can obtain an IP address but your PC is unable to load any web pages from the
Internet:
• Your PC 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’s configuration, reboot
your PC and verify the DNS address as described in
“Verifying TCP/IP Properties (Windows)“
on page 3-5. Alternatively, you may configure your PC manually with DNS addresses, as
explained in your operating system documentation.
• Your PC may not have the modem configured as its TCP/IP gateway.
If your PC obtains its information from the modem by DHCP, reboot the PC and verify the
gateway address as described in
“Verifying TCP/IP Properties (Windows)“ on page 3-5.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
modem’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 Default Reset button on the rear panel of the modem. Use this method for cases when
the administration password or IP address is not known.
Using the Default Reset button

or IP address, you must use the Default Reset button on the rear panel of the modem.
