Check the lights on the front panel. Note the first light from top to bottom that is off. This light indicates where the error occurred as described in “Front-Panel Lights and Error Conditions” on page 37.

If all lights are off except the Standby light, the cable modem is in Standby mode. Press the Standby button to reconnect your Internet service.

If you have cable TV, check that your TV is working and the picture is clear. If you cannot receive your regular TV channels, your data service will not function.
