Many broadband ISPs restrict access by allowing traffic only from the MAC address of
your modem, but some additionally restrict access to the MAC address of a single
computer connected to that modem. In this case, configure your modem router to clone
or spoof the MAC address from the authorized computer (see Manually Set Up an ADSL
Internet Connection on page 47).
