> ### Query DNS For ISP Test
> Pass: | Indicates that the Domain Name Server (DNS) can resolve the domain name of ISP to an IP address.
> Fail: | Indicates that the DSL modem was unable to resolve the domain name. This test may not have an effect on your Internet connectivity. Therefore if this test fails, but you are still able to access the Internet, there is no need to troubleshoot this issue.
If the test fails, follow the troubleshooting procedures listed below and rerun the diagnostics tests by clicking on the Rerun Diagnostic Tests button at the bottom of this page. If all the tests pass, close and restart your Web browser to access the Internet. Troubleshooting: NOTE: If Ping Primary Domain Name Server fails, this test result displays N/A. Turn off the DSL modem, wait 10 seconds, and turn it back on. Wait at least one minute for the modem to completely restart and to establish a connection. If the PPPoE LED is on and the modem turns solid green, close your Web browser then restart it. With the modem on, press the external reset button on the DSL modem for at least five seconds and release it. This resets the DSL modem to its default settings. Wait for the DSL modem to completely restart, then close and restart your Web browser. To reconfigure the modem, type your DSL Account username and password. Contact ISP Technical Support if you have tried all of the above and still are experiencing a fail condition.
