Wireless Cable Voice Gateway CG3000/CG3100 User Manual

Troubleshooting the ISP Connection

If your gateway is unable to access the Internet and your Cable Link LED is on, you may need to register the Cable MAC Address and/or Device MAC Address of you gateway with your cable service provider.

Additionally, your PC may not have the gateway configured as its TCP/IP gateway. If your PC obtains its information from the gateway by DHCP, reboot the PC and verify the gateway address. See the link to the online document “ITCP/IP Networking Basics” in Appendix B.

Troubleshooting a TCP/IP Network Using a Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made easier by using the ping utility in your PC or workstation.

Testing the LAN Path to Your Gateway

You can use ping to verify that the LAN path to your gateway is set up correctly. To ping the gateway from a PC running Windows 95 or later:

1.From the Windows toolbar, click on the Start button and select Run.

2.In the field provided, type Ping followed by the IP address of the gateway, 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
