AC3200 WiFi Cable Modem Router
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 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.
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 like those shown in Test the LAN Path to Your
Modem Router on page 108 display.
If you do not receive replies, check the following:
• Check to see that the IP address of your 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. 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. If your ISP additionally restricts access to the MAC address of a
single computer connected to that modem, configure your modem router to “clone” or
“spoof” the MAC address from the authorized computer.
