Many DOCSIS modems have an internal diagnostic web page server built-in. This is so that the end user and technicians can check signal levels, log files, and other important details about the health of the cable modem's connection. The follow is a list of popular modems and their diagnostic page address. Just click the link for your modem model.
Standard address for most modems: 192.168.100.1
Com21
DPX-1110 (3-color Com21 label on top): Modem's private (10.xxx.xxx.xxx) IP address.
Usually this can be obtained by tech support or those with access to the CMTS.

Some pages request a password, leave it blank and continue.
TJ-715 and 715x: 192.168.100.1/diagnostics_page.html
It needs password, so search Google for it.
Sometimes it's necessary to power cycle the modem to access the diagnostic page after it has been online awhile.
ZyXel
Prestige 944: 192.168.1.1.
For modems without internal diagnostic pages, try the utility: DOCSDIAG. This has been rendered useless in most Adelphia systems due to increased security measures Adelphia has enacted in an attempt to prevent modem hacking.
Note: Many home routers will interfere with access to these internal webpage addresses unless the router's routing tables have been specifically configured for it. The easiest way to prevent this problem is directly connect the modem to the computer when you need to check the diagnostic page.
