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 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 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 in the Internet Setup screen.

Your ISP could 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 so, configure your router to “clone” or “spoof” the MAC 
address from the authorized computer.
