If the path is not functioning correctly, one of the following problems might be occurring:
•
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 to see that the appropriate LEDs are lit for your network devices. If your 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 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 router and your computer are correct and that the
addresses are on the same subnet.
Test the path from a Windows-based computer to a remote
device
To test the path from a Windows-based computer to a remote device:
1. From the Windows toolbar, click the Start button and select Run.
2. In the Windows Run window, type
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, messages display that are similar to those shown
in Test the LAN path to your router on page 196.

If you do not receive replies, check the following:
•
Check to see that IP address of your router is listed as the default gateway for
your computer. If DHCP assigns the IP configuration of your computers, this
information is not visible in your computer Network Control Panel. Verify that the
IP address of the router is listed as the default gateway.
•
Check to see that the network address of your computer (the portion of the IP
address specified by the subnet mask) is different from the network address of
the remote device.
•
Check to see that your cable or DSL modem is connected and functioning.
•
If your ISP assigned a host name to your computer, enter that host name as the
account name on the Internet Setup page.
•
Your ISP might be rejecting the Ethernet MAC addresses of all but one of your
computers.
