Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is lit for the
port to which you are connected.
Check that the appropriate LEDs are on for your network devices. If your cable
modem router and computer are connected to a separate Ethernet switch, make
sure that the link LEDs are lit for the switch ports that are connected to your
computer and cable modem router.
•
Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer.
Verify that the IP address for your cable modem router and your computer are
correct and that the addresses are on the same subnet.
Test the Path From Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to
a remote device.

•
Check to see that the IP address of your cable modem router is listed as the
default gateway on your computer. If DHCP assigns the IP configuration of your
computers, this information is not visible in your computer Network Control Panel.
