Troubleshooting the Ethernet 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
the Wireless LAN Cable Modem and wait for 5 seconds and power on the modem
again. If the problem still exists, you may have a hardware problem.
The ethernet 1 or 2 or 3 or 4 LED on my wireless cable modem is not lit.
Try restarting the computer so that is could re-establish a connection
with the wireless 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 manufactures documentation or you cable
service provider for further assistance.
Verify that TCP/IP is the default protocol for your network interface card (NIC)
