8 DDW2600 Wireless Cable Modem - FAQ • May, 2010
1.7 Troubleshooting Q & A Use the following tips for resolving general issues with the device.
1. None of the LEDs are on when I power on the cable modem.
Check the connection between the power adapter and the cable
modem. Power off cable modem and wait for 5 seconds and power
on the modem again. If the problem still exists, there may have a
hardware problem.
2. The Ethernet 1, 2, 3, or 4 LED on the cable modem is not lit.
Try restarting the computer so that is could re-establish a
connection with the cable modem.
Check for a resource conflict (Windows users only). To do this: (1)
Right-click on the My Computer icon on your desktop and choose
Properties. (2) Click the Device Manager tab and look for a yellow
exclamation point or red X over the NIC in the Network Adapters
field. If you see either one, you may have an IRQ conflict. Refer to
the manufacturers documentation or you cable service provider for
further assistance.
Verify that TCP/IP is the default protocol for your network interface
card (NIC).
Power cycle the cable modem by removing the power adapter from
the electrical outlet and plugging it back in. Wait several minutes
for the cable modem to re-establish communications with your
cable service provider.
3. General Connectivity Issues:
If your PC is connected to a hub or gateway, try connecting the PC
directly into an Ethernet port on the cable modem.
If you are using a cable splitter, try removing the splitter and
connect the cable modem directly to the cable wall outlet. Wait
several minutes for the cable modem to re-establish
communications with the cable service provider.
The Ethernet cable may be damaged. Try another cable.
4. If none of these suggestions work, contact your cable service
provider for further assistance.
5. My Ethernet device won’t connect to the network.
If the Ethernet device is a computer, it is possible that the computer
does not have DHCP server enabled, which allows it to obtain an
IP address and join the network. See the steps below:
