CENTRIA WNDR4700/WNDR4720
Restore the Factory Settings and Password
This section explains how to restore the factory settings, changing the router’s administration password back to password. You can erase the current configuration and restore factory defaults in two ways:
•Use the Erase function of the router (see Erase on page 96).
•Use the Reset button on the back of the router. See Factory Settings on page 138. If you restore the factory settings and the router fails to restart, or the green Power 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 http://www.netgear.com/support.
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 CENTRIA
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 then 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
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
•Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is on for the port to which you are connected.
