AC1900 Cable Modem Voice Router
• 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 to see 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 on the Internet Setup page.
• 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. If your ISP restricts access to the MAC address of a single
computer connected to that modem, configure your modem router to “clone” or “spoof”
the MAC address from the authorized computer.
