DOCSIS 1.0/ 1.1 Equivalent Cable Modem Appendix B: Questions and Answers Section 1: Troubleshooting Modem LED Problems Troubleshooting the modem portion of this Cable Modem begins with observing the front panel lights (also called LEDs - light emitting diodes). The pattern of these lights indicates the status of the modem. Interpreting the pattern correctly can indicate whether the modem is functioning properly or not. If there is a problem, the lights provide clues as to what the problem might be.
DOCSIS 1.0/ 1.1 Equivalent Cable Modem Question 3: The LAN Light Is Off Answer: If the LAN light is on, the Cable Modem's Ethernet port is connected to the computer correctly. If the modem is having problems transferring data, check the Cable light, as described in the above Cable Light subsection, to determine the state of the modem. If the LAN light is off, the modem is not detecting the Ethernet network interface card. Possible Solutions: 1.
