Troubleshooting PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1.
Log in to the wireless-N router.
2. Select Router Status under Maintenance on the main menu.
3. Click Connection Status. If all of the steps indicate “OK,” then your PPPoE connection is up
and working.
If any of the steps indicate “Failed,” you can attempt to reconnect by clicking Connect. The
wireless-N router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name,
user name, or password. There also might be a provisioning problem with your ISP.
Troubleshooting Internet Browsing
If your wireless-N router can obtain an IP address but your computer is unable to load any web
pages from the Internet, check the following:
• Your computer might 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 wireless-N router’s configuration, restart your computer.
Alternatively, you can configure your computer manually with a DNS address, as explained in
the documentation for your computer.
• Your computer might not have the wireless-N router configured as its default gateway.
Reboot the computer and verify that the wireless-N router address (192.168.1.1) is listed by
your computer as the default gateway address.
Using the Ping Utility to Troubleshoot
Most computers and routers have a diagnostic utility called ping that sends a request to a target
device. The device then replies. The ping utility makes it easy to troubleshoot a network.
Unless you connect manually, the wireless-N router will not authenticate using
PPPoE until data is transmitted to the network.
