Terayon TJ 700x Series DOCSIS Cable Modem Installation Guide
Troubleshooting
Problem:
I cannot access my E-mail or Internet Service.
Possible solution:
Check all connections. Make sure the cable line is securely connected to the cable jack on
the back of the modem. Verify the Ethernet or USB cable is securely plugged into both
the modem and your network interface card or USB network interface. Make sure your
Power Adaptor is properly plugged into both the modem and a wall outlet or surge
protector. If your cable modem is properly connected, the Cable and PC indicator lights
on the modem front panel should be a solid color.
If the Cable and PC indicator lights (LEDs) are solid green (not blinking), your cable
modem is operating properly. Try shutting down and powering off your computer and
then turning it back on. This will cause your computer to re-establish communications
with your cable company server.
1. If you are using the cable line splitter, try bypassing the splitter by disconnecting it
and running a single coaxial cable between the cable modem and your cable wall jack.
Try reconnecting after making this change. If reconnecting is successful, you may
have a bad splitter.
2. Your network interface card may be malfunctioning. Refer to the Manufacturer’s doc-
umentation for troubleshooting information.
3. Call your cable company to verify their service is two-way. This modem is designed
for use with two-way cable plants. Verify your account is activated.
Problem:
The Cable LED never stops blinking.
Possible Solution:
The signal from your cable company equipment may be too weak or the cable line may
not be properly attached to the modem. If the cable line is properly connected to the
modem, call your cable company to verify whether or not a weak signal may be the
problem.
