NETGEAR LB2120 Series User Manual

• Check to see that your computer lists the IP address of your modem as the default router. If the IP
configuration of your computer is assigned by DHCP, this information is not visible in your computer’s
Network Control Panel.
• Check to see that the network address of your computer (the portion of the IP address specified by the
netmask) is different from the network address of the remote device.
Many mobile broadband service providers 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 the modem. In this case, inform your service provider that you bought a new network device, and ask
them to use the modem’s MAC address.
