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. 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.
Question 4: The RX Light Is Off
Answer:
The RX Light flickering On and Off indicates that the cable network is successfully
receiving data. If the RX light is off, then the cable network is not receiving data
from the modem.
If the cable network is having problems transferring data, check the Cable light as
described above.
Question 5: The TX Light Is Off
Answer:
The TX Light flickering On and Off indicates that the cable network is successfully
transmitting data. If the cable network is having problems transferring data, check
the Cable light, as described above.
If the TX light is off, then the cable network is not transmitting data to the modem. If
the modem is having problems transferring data, check the Cable light, as described
above.
Question 6: All LEDs look right, but I still cannot access the Internet
Answer:
If the Power, Cable LEDs, and LAN LED are lighted, the cable modem is operating
properly. Try shutting down the computer and then turning it on. This causes the
computer to re-establish communications with your cable service provider’s computer.
Power cycle the cable modem by removing the power adapter from its outlet and then
plugging it back into the outlet. Then try reconnecting to your cable service provider.
Verify that you have installed TCP/IP properly, and that the TCP/IP parameters
provided by your cable service provider are correct for your computer.
If you are using a cable line splitter so that you can connect the cable modem and a
television at the same time, try removing the splitter and reconnecting the cables so
that the cable modem is connected directly to the cable wall jack. Then try
reconnecting to your cable service provider.
