N600 Wireless Dual Band Router WNDR3400v3

Wireless Signal Strength

If your wireless device finds your network, but the signal strength is weak, check these
conditions:
Is your router too far from your computer, or too close? Place your computer near the
router, but at least 6 feet away, and see whether the signal strength improves.
Is your wireless signal blocked by objects between the router and your computer?

Restore the Factory Settings and Password

To restore the factory settings, erasing the current configuration, and changing the router’s
administration password back to password, you can:
Use the Erase function of the router (see Erase on page 73).
Use the Restore Factory Settings button on the back of the router. See Factory Settings
on page 106. If you restore the factory settings and the router fails to restart, or the green
Power/Test LED continues to blink, the unit might be defective. If the error persists, you
might have a hardware problem and should contact technical support at

Troubleshoot Your Network Using the Ping Utility

Most network devices and routers contain a ping utility that sends an echo request packet to
the designated device. The device then responds with an echo reply. You can easily
troubleshoot a network by using the ping utility in your computer or workstation.

Test the LAN Path to Your Router

You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a running Windows computer:
1. From the Windows toolbar, click Start, and select Run.
2. In the field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3. Click OK.
You should see a message like this one:
Pinging <IP address > with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
