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, see

Check that the corresponding LEDs are on for your network interface card and for
the hub ports (if any) that are connected to your workstation and gateway.
•
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 gateway and your workstation are correct and
that the addresses are on the same subnet.
