N150 Wireless ADSL2+ Modem Router DGN1000
Debug PPPoE or PPPoA
To debug the PPPoE or PPPoA connection:
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 wireless 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 wireless modem router does not
authenticate with PPPoE or PPPoA until data is transmitted to the
network.
Cannot Load an Internet Web Page
If your wireless 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 wireless 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 wireless modem router configured as its TCP/IP
wireless modem router.
If your computer obtains its information from the wireless modem router by DHCP, reboot
the computer, and verify the wireless modem router address.
TCP/IP Network Not Responding
Most TCP/IP terminal devices and routers have a ping utility for sending an echo request
packet to the designated device. The device responds with an echo reply to tell whether a
TCP/IP network is responding to requests.
