Troubleshooting the Installation
Use the following tips to troubleshoot the installation.
None of the LEDs are on when I power on the DDW36C.
Check the connection between the power outlet and the power cord. Verify the
power outlet is energized and the power cord is connected to the power outlet.
Check the connection between the power cord and the cable modem. Power off
the cable modem and wait for 5 seconds and power on the modem again. If the
problem still exists, there may be a hardware problem.
The ETHERNET 1, 2, 3, or 4 LEDs on the back of the modem are not lit where
Ethernet cables are connected.
Restart the computer so that it can re-establish a connection with the cable
modem.
Check for a resource conflict (Windows users only):
1. Right-click
My Computer
on your desktop and choose
Properties
.
2. Choose the
Device Manager
tab and look for a yellow exclamation point or red
X
over the
network interface card (NIC) in the Network Adapters field. If you see either one, you may
have an interrupt request (IRQ) conflict. Refer to the manufacturer’s documentation or ask
your service provider for further assistance.
Verify that TCP/IP is the default protocol for your network interface card.
Power cycle the cable modem by removing the power cord from the electrical
outlet and plugging it back in. Wait for the cable modem to re-establish
communications with your cable service provider.
