• Log in to the modem router as described in “Logging In to the Modem Router” on page 1-2 ,
note the modem router status, run the diagnostics test as described in “Diagnostic Utilities and
Rebooting the Modem Router” on page 2-11 , and contact your ISP’s technical support
representative.
Troubleshooting PPPoE or PPPoA Connection
The PPPoA or PPPoA connection can be debugged as follows:
1. Access the Main Menu of the router at http://192.168.0.1.
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” in Appendix B . 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” in Appendix B .
Note: Unless you connect manually, the modem router will not authenticate using PPPoE
or PPPoA until data is transmitted to the network.
