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 168.
3. 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.
Many broadband ISPs restrict access by allowing traffic only from the MAC address
of your broadband modem. Some ISPs additionally restrict access to the MAC address
