Wireless Cable Modem Gateway CGD24G User Manual
If the path is not working correctly, you could have one of the following problems:
•Wrong physical connections.
–Make sure the LAN port LED is on. If the LED is off, see “Using LEDs to Troubleshoot” on page
–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 gateway.
•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 gateway and your workstation are correct and that the addresses are on the same subnet.
Testing the Path from Your PC to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to a remote device. From the Windows run menu, type:
PING
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 in the previous section are displayed. If you do not receive replies:
•Check that your PC has the IP address of your gateway listed as the default gateway. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the gateway is listed as the default gateway. See the link to the online document “ITCP/IP Networking Basics” in Appendix B.
•Check to see 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 Link LED is on.
•If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings menu.
