Use and Care Manual

Verify that the IP address for your modem 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 127.

If you do not receive replies, check the following:
•
Check to see that IP address of your modem 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 modem 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
of a single computer connected to that modem. If your ISP does this, configure your
modem router to “clone” or “spoof” the MAC address from the authorized computer.
