N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000
Troubleshoot PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1.Log in to the wireless modem router.
2.Select Administration > Router Status.
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 modem router continues 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 might also be a provisioning problem with your ISP.
Note: Unless you connect manually, the wireless modem router does not authenticate using PPPoE until data is transmitted to the network.
Troubleshoot Internet Browsing
If your wireless modem 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 provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the wireless modem 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 modem router configured as its default gateway.
Reboot the computer, and verify that the wireless modem router address (www.routerlogin.net) is listed by your computer as the default gateway address.
•You might be running login software that is no longer needed. If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that software after installing your wireless modem router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection.
