•Check that your computer has the IP address of your wireless modem 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’s Network Control Panel. Verify that the IP address of the wireless 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 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 Basic Settings screen.
•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, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If so, then configure your wireless modem router to “clone” or “spoof” the MAC address from the authorized computer.
