Hi James,

Thanks for the link. I receieved that quick start booklet with my modem and have followed that. For extra detail I downloaded the detailed user manual that talked about switching router mode to feed directly into my D7000 router. I have followed all of the instructions without any success.

I would be greatful for more detail on the requred settings in both devices.

    Hi JamesGL, 

    The firmware of the LB1210 is up to date - I have performed the search for new software a few times now.

    Firmware is M18QW_v07.05170721. The device is the Ausralian version if that matters.

     

    My Nighthawk D7000 is on firmware V1.0.1.50_1.0.1

      Hi JamesGL,

      Just wondering if I can expect a response or should I just go to customer support?

        Hi  gyorsto,

         

        If your PC is getting an IP address from the LB2120 and you can access the internet then the issue sounds like it is on the D7000 side.  There are a few things you can try.

         

        1. Disable bridge mode on LB2120 and enable access point mode on D7000.  DHCP will be from LB2120 in this mode.

        2. Disable bridge mode on LB2120, set a specific IP address as DMZ on LB2120 (i.e 192.168.5.90) and then set this IP as a static IP in the D7000 internet setup page.

         

        The above is assuming you do not want to use ADSL and will use LTE as your dedicated connection.  If you are wanting to use the failover mode and have ADSL as your primary and then failover to LTE then you need to configure the failover settings on the LB2120 and plug ethernet cable from D7000 lan to LB2120 WAN port.

         

        Kind Regards,
