General Cable Modem Troubleshooting

All cable modems have a series of lights on the front of the cable modem. The configuration of lights varies across different cable modem manufacturers and models, but some troubleshooting generalizations can be made:

1. All cable modems have a POWER light that indicates whether the cable modem is on or off.
2. All cable modems have a CABLE light, sometimes called a STATUS or ERROR light, which indicates whether or not the cable modem is connected to the AT&T Broadband Cable Internet Service network.
3. Most cable modems have at least one light that indicates if the cable modem is receiving information from the computer. These lights are labeled differently on various cable modems. Some possible labels include the DATA light, the ACTIVITY light, the ACTIVE light, the STATUS (connected or not) and ACTIVITY (transmitting) lights or the RD (cable modem to computer) and TD (computer to cable modem) lights.
4. Some cable modems have a light that indicates whether data is being transmitted over the cable connection. This is called the CABLE ACTIVITY light.
5. Many cable modems have a TEST light. If the TEST light is flashing, then the cable modem is performing the self-test. If it is lit, then the cable modem has likely failed the self-test.
