2.3 Troubleshooting the Installation
Use the following tips for troubleshooting the installation.
 None of the LEDs are on when I power on the Wireless LAN Cable Modem.
 Verify the power outlet is energized and the power adaptor is connected to the
power outlet.
 Check the connection between the power adapter and the cable modem. Power off
cable modem by removing the power cord from the back of the unit. Wait for 5
seconds and power on the modem again. If the problem still exists, there may be
a hardware problem.
 The Ethernet LED on the cable modem is not lit.
 Verify both ends of the Ethernet cable are properly connected.
 Restart the computer to 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. Click the Hardware tab, and then choose Device Manager.
3. 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.
4. Refer to the manufacturers documentation or contact the cable service provider
for further assistance.
 Verify 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 until the cable modem re-establishes
communications with the cable service provider.
 General Connectivity Issues:
 If your PC is connected to a hub or gateway, connect the PC directly into an
Ethernet port on the cable modem.
 If you are using a cable splitter, remove 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 the cable service provider for further
assistance.
