To ping the modem router from a PC running Windows 95 or later:
1. From the Windows task bar, 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 on. If the LED is off, follow the instructions in
LAN LED Is Off on page 102.
- 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 Test the LAN Path to Your Modem
Router on page 105 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.
