N600 Wireless Dual Band Router WNDR3400v3
If any of the steps indicate Failed, you can attempt to reconnect by clicking Connect. The
router continues to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name,
use
r name, or password. There might also be a provisioning problem with your ISP.
Note: Unless you connect manually, the router does not authenticate using
PPPoE until data is transmitted to the network.
Troubleshoot Internet Browsing
If your 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
entered a DNS address during the router’s configuration, restart your computer.
Alternatively, you can configure your compu
ter manually with a DNS address, as
explained in the documentation for your computer.

our computer might not have the router configured as its default gateway.
Reboot the computer, and verify that the router address (www.routerlogin.net) is listed by
you

program to log you in to the Internet (such as WinPoET), you no longer need to run that
software after installing your 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 router does not save changes you have made in the browser interface, check the

en entering configuration settings, be sure to click Apply before moving to another
screen or tab, or your changes could be lost.
• Click Re

web browser might be caching the old configuration.
