Troubleshooting Steps
- Turn off the broadband modem and your computer. Wait for one minute. Turn on the broadband modem and then power on your personal computer.
- Verify all connections are in place and connected securely. Check the coax cable connected to the transceiver power supply, coax cable connected to the broadband modem and the Ethernet cable connection between the broadband modem and the computer or hub.
- Verify the power supply to each piece of equipment is plugged in and receiving power. Check the digital transceiver, broadband modem, computer and hub.
- Check the LINK light on the broadband modem, computer and hub (if applicable). If there is not LINK light on an Ethernet port, make sure you are using the correct type of Ethernet cable. Try swapping the Ethernet cable for another cable on a connection that is working. This should provide insight into what is failing (cable or port). If a certain port is failing, try to power off the unit and then power it on again after one minute.
- Check the LOCK light on the front of the broadband modem. It should be illuminated. If the LOCK light is out, trace the coax cable connection from the back of the broadband modem to the digital transceiver power supply. Make sure the power supply is on. Once you have verified that the transceiver's power supply is connected to the power outlet, re-check the LOCK light. Allow up to one minute for the light to illuminate. If the LOCK light is still not on, the modem is having difficulties receiving signal. It may need to be serviced -- contact our technical support staff at
