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
For a wired connection, make sure that the numbered LAN port LED is lit for the port to
which you are connected.
Check that the appropriate LEDs are lit for your network devices. If your modem router
and computer are connected to a separate Ethernet switch, make sure that the Ethernet
LEDs are lit for the switch ports that are connected to your computer and modem router.
•
Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed and
configured on your computer.
Verify that the IP address for your modem router and your computer 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
remote device.
1.
From the Windows toolbar, click the
Start
button, and then select
Run
.
2.
In the Windows Run window, type:
ping -n 10
<
IP address
>
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies like the examples shown in the previous section are
displayed.
If you do not receive replies:
•
Check that your computer has the IP address of your modem router listed as the default
gateway. If the IP configuration of your computer is assigned by DHCP, this information is
not visible in your computer’s Network Control Panel. Verify that the IP address of the
modem router is listed as the default gateway.
•
Check to see that the network address of your computer (the portion of the IP address
specified by the subnet mask) is different from the network address of the remote device.
