Terayon TJ 700x Series DOCSIS Cable Modem Installation Guide

21

Problem:

The power on my modem goes on and off sporadically. The Cable LED never 
stops blinking.

Possible Solution:

You may be using the wrong power supply. Check that the power supply you are using is 
the one that came with your cable modem. If you cannot connect to the Internet at all, 
use this checklist to help identify possible problems:

Make sure your computer and monitor are turned on.

Make sure all power plugs are completely inserted into their sockets.Your computer 
and cable modem should be plugged into grounded outlets.

If you are using a power strip, make sure it is turned on.

Make sure all data cables are firmly connected at both ends.

If you still do not have a connection, call your cable service to confirm they have prop-
erly set you up for service. If so instructed, reset your modem.

Problem:

I have two PCs connected to the modem, but only one PC can access the Internet.

Possible Solution:

Call your cable company to check your terms of service. Your cable operator may only 
allow one computer to connect to the modem.
