• Your computer might not have the modem router configured as its TCP/IP modem router.

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 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 functioning correctly, you could have one of the following problems:
• Wrong physical connections
– Make sure that the LAN port LED is on. If the LED is off, follow the instructions in
"LAN or Internet Port LED Is Not On" on page
– Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
