NETGEAR DOCSIS C6230 User Manual page 103

Verify that the IP address of the cable 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 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 additionally restricts access to the MAC
address of a single computer connected to that modem, configure your cable modem
router to "clone" or "spoof" the MAC address from the authorized computer.
