Nighthawk Mesh WiFi 6 System
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 your ISP does this, configure your router
to "clone" or "spoof" the MAC address from the authorized computer.
