• Bad or loose cable connections
• Unterminated connections
• Problem with the cable on the street
• Problem in the cable network
Possible Solutions:
1. Disconnect and then reconnect the power. This will automatically reset the modem.
2. Wait at least 4 minutes.
3. If the Cable light is still off, then there could be a problem with the cable wiring. Check all cables between the modem and the ground
terminal outside the house. Unplug the power again, and then plug it back in as before.
4. If the Cable light is still off, there might be a problem with the cable network or the modem. Contact your cable provider.
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. Make sure the cable between your computer’s Ethernet card and the modem is securely fastened at each end.
2. There may be a green “carrier detect” light on the back of the Ethernet card. It should be a steady green. If the cable is securely connected,
then the Ethernet card may have loosened from its socket. Open up the computer and make sure the card is firmly seated in place.
3. If you have plugged a hub into the port, you need to use a crossover Ethernet cable instead of a straight through cable.
4. Try replacing the cable between the modem and the Ethernet card.
5. If the problem persists, it could indicate a problem with the Ethernet card or the modem. Contact the manufacturer of the Ethernet card or your
cable provider.
