C:\Netgear directory.)
4. Click Upgrade.

firmware recovery is complete, the login screen for the Smart Wizard displays, allowing you
to log in to the wireless-N modem router to check its status.
Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal 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 TCP/IP network by using the ping utility in your computer.
Testing the LAN Path to Your Wireless-N Modem 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 PC running Windows 95 or later:
1. From the Windows toolbar, click the Start button, and select Run.
2. In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.0.1
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
