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. You 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 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
If the path is not working correctly, you could have one of the following problems:
•
Wrong physical connections

Make sure that the LAN Ports LED is on. If the LED is off, follow the instructions in

Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your computer or workstation.
