Troubleshoot 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. Y ou can easily
troubleshoot a TCP/IP network by using the ping utility in your computer.

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 computer 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
If the path is not working correctly, you could have one of the following problems:
•Wrong physical connections
- Make sure that the LAN Port LED is lit. If the LED is off, follow the instructions in
Connecting to the Internet on page 100.
- Check that the corresponding link LEDs are lit for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
•Wrong network configuration
- Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your computer or workstation.
- Verify that the IP address for your router and your workstation are correct and that
the addresses are on the same subnet.

Test the Path from Your Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your computer to a remo te
device.
