Validate Connectivity/Connect Devices to the Network
To confirm network/internet operations, or to connect an
Ethernet
device to the
network (for example, a computer, gaming console, etc.), do the following:
1.
Make sure the Ethernet device (computer, gaming console) to add to the network
is connected to the cable modem and powered on. Refer to
page 7
, if needed.
2.
Use the device LEDs to confirm operations. The PWR, DS, US, Online, and Wifi
LEDs are solidly lit in normal operations, as is the LAN LEDs that have devices
connected to their associated ports. Refer to “LED Operational Summary” on
page 5
for more detailed information.

. On a
Windows computer, for example, double-click the Wireless Networking icon in

Additional Troubleshooting Information
Use the following tips for troubleshooting the installation.
None of the LEDs are on when I power on the Wireless LAN 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.
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.
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.
If none of these suggestions work, contact your cable service provider for further
assistance.
