N300 Wireless Gigabit ADSL2+ Modem Router DGN3500 User Manual
Troubleshooting PPPoE or PPPoA
The PPPoE or PPPoA connection can be debugged as follows:
1.
Access the main menu of the router at http://192.168.0.1.
2.
Under Maintenance, select
Router Status
.
3.
Click the
Connection Status
button.
4.
If all of the steps indicate OK, then your PPPoE or PPPoA connection is up and working.
5.
If any of the steps indicates Failed, you can attempt to reconnect by clicking
Connect
. The
wireless modem 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.
Note:
Unless you connect manually, the wireless modem router will not
authenticate using PPPoE or PPPoA until data is transmitted to the
network.
Troubleshooting 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:
•
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 as described in
the online document that you can access from
Preparing Your Network
on page 117.
Alternatively, 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 as described in the online
document that you can access from
Preparing Your Network
on page 117.
