N600 Wireless Dual Band Gigabit VDSL2 Modem Router DGND3800B
Debug PPPoE or PPPoA
Debug the PPPoE or PPPoA connection as follows:
1. Access the router menus at http://192.168.0.1 and log in.
2. Under Maintenance, select Router Status.
3. Click the Connection Status button.
4. If all of the steps indicate OK, your PPPoE or PPPoA connection is working.
5. If any of the steps indicate Failed, you can attempt to reconnect by clicking Connect.
The modem router continues to attempt to connect indefinitely. If you do not connect after
several minutes, check that the service name, user name, and password you are using
are correct. Also check with your ISP to be sure that there is no problem with their
service.
Note: Unless you connect manually, the modem router does not
authenticate with PPPoE or PPPoA until data is transmitted to the
network.
Cannot Load an Internet Web Page
If your modem router can obtain an IP address, but your browser cannot load any Internet
web pages:
• 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 modem router’s
configuration, reboot your computer, and verify the DNS address. Alternately, you can
configure your computer manually with DNS addresses, as explained in your operating
system documentation.
• Your computer might 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.
