installed and configured on your computer or workstation.
– Verify that the IP address for your router and your workstation are correct
and that the addresses are on the same subnet.
Testing 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. From the Windows run menu, type:
PING -n 10 <IP address>
where < IP address > is the IP address of a remote device such as your ISP’s DNS
server.
If the path is functioning correctly, replies as in the previous section are displayed. If you
do not receive replies:
•
Check that your computer has the IP address of your router listed as the default
gateway. If the IP configuration of your computer is assigned by DHCP, this
information will not be visible in your computer’s 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 netmask) is different from the network address of the
remote device.
•
Check 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
User Name in the WAN Interface menu.
•
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your
computers. Many broadband ISPs restrict access by only allowing traffic from the
MAC address of your broadband modem, but some ISPs additionally restrict
access to the MAC address of a single computer connected to that modem. If
this is the case, you must configure your router to “clone” or “spoof” the MAC
address from the authorized computer. To do this, click on the WAN Interface link
under the TCP/IP heading of the browser interface at
192.168.2.254 , and enter
the authorized computer’s MAC address under “Clone MAC Address”.
