In the field provided, type ping followed by the IP address of the modem router, as in this 

example:

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 

135.

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 modem 
router.

Wrong network configuration

Verify that the Ethernet card driver software and TCP/IP software are both 

installed and configured on your PC 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 PC 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 

138 display. If you do not receive replies:

Check that your PC has the IP address of your modem router listed as the default modem 

router. If the IP configuration of your PC is assigned by DHCP, this information is not 
visible in your PC’s Network Control Panel. Verify that the IP address of the modem 
router is listed as the default router.

Check that the network address of your PC (the portion of the IP address specified by the 

netmask) is different from the network address of the remote device.

Check that your cable or DSL modem is connected and functioning.
