that may be useful to your cable company if you are having startup or operation issues. As long
as your gateway startup and operational performance is normal, any messages contained in this

Diagnostics Web Page (Fig. 21)
This page verifi es you have IP connectivity from your gateway to other IP addresses on the LAN
side, such as when you want to confi rm you have successfully confi gured one of your PCs for
TCP/IP operation.
When you ping an Internet device, you send a packet to its TCP/IP stack, and it sends one back to
yours. Enter the IP address you want to ping, then click Start Test. Wait a few seconds, then click
your web browser’s refresh button. Success reported in the Results box means IP connectivity is
working from your CM TCP/IP stack to the target’s stack.
Note: Firewalls may cause pings to fail but still provide you TCP/IP access to selected devices behind them. Keep
this in mind when pinging a device that may be behind a fi rewall. Ping is most useful to verify connectivity with
PCs you know have no fi rewall, such as your own PCs on your LAN side.
