Wireless Cable Modem Gateway CG814WG v3 Reference Manual

Troubleshooting

5-5

v1.0, June 2007

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 -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 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 

“Internet Networking and TCP/IP Addressing” 

on page B-1

.

•

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.
