Test the LAN Path to Your Modem Router
You can ping the modem router from your computer to verify that the LAN path to your
modem router is set up correctly.
To ping the modem router from a computer running Windows 95 or later:
1.
From the Windows taskbar, click the Start button, and select Run.
2.
In the field provided, type ping followed by the IP address of the modem 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 lit. If the LED is off, follow the instructions in
LED Is Off
•
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 modem 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 you verify that the LAN path works correctly, test the path from your computer to a
remote device. In the Windows Run screen, 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 as described in

•
Check that your computer has the IP address of your modem router listed as the default
modem router. If the IP configuration of your computer is assigned by DHCP, this
