Troubleshooting
Problem: Cannot connect to the Internet
Verify all cables are securely connected to cable modem, computer, and power source. If the power outlet is
controlled by a switch, make sure the switch is turned ON. (The PipeRider cable modem should be installed
and operated using the cables and power supply provided with the modem. Ericsson does not guarantee
performance with any other cables, cable extensions, or power supplies.)
1.
If you subscribe to cable TV, check to see if you are receiving a TV signal. If not, this indicates that you are
not receiving signals through the cable. Report the problem to your Service Provider.
2.
Confirm that your local Service Provider has established an Internet account for you, and that your provider
supports two-way cable modem access.
3.
Perform a reset by unplugging the modem, waiting for at least 10 seconds, and then plugging it back in.4.
The LEDs on the top of the PipeRider cable modem may help you narrow down the cause of the problem. It is
recommended that you familiarize yourself with the function of the PipeRider LEDs and the various
operational states of the modem. After the modem has completed the initialization phase, you can refer to
