Troubleshoot PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1. L
og in to the wireless modem router.
2. Select Admini
stration > Router Status.
3. Click Conne
ction 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 atte
mpt 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,
u
ser name, or password. There also might 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:
• Y
our 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
e
ntered 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.
• Y
our 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.
• Y
ou 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.
If the wireless modem router does not save changes you have made in the browser
