LM1200 wan connection not working

I want to use LM1200 as a failover device in the North Sierras where when we lose power, the broadband goes out in 20 mins. I have the latest firmware and if I connect only LTE modem it works fine. F...

    Thank you John.

     

    I switched to Router mode and I was able get the traffic through. That caused me another problem since the port numbers using public IP was not translated to local IP.

     

    I switched to Bridge mode again and modem stayed connected and everything works great.

    Thanks for all the help, now I need to find external antennas to improve the LTE reception.

Please check some basic things first.

 

1. Your FW is the latest: 20.06.09.00

2. The ethernet cable connecting to your home cable modem is connected to the WAN port of LM1200. 

3. Pleae check the failover settings is set to Auto.

 

If all are set correctly, please do a factory reset and try again. If possible, try a new ethernet cable.

 

Thanks

Hi John,

 

1. Yes, the App Version is NTG9X07C 20.06 09.00

2. ethernet cable is connected to the WAN port. If you look at the picture that I attached, it shows that the port received an IP address from my router. When I connect LM1200 to the Cable Modem it also gets a IPv6 address but same thing happens, no connection (the x mark). 

3. Failover is on Auto.

4. I tried multiple cables, no change.

It just does not want to pass traffic on the broadband side. LTE works fine.

    Please connect the LM1200 to your home cable modem and help to capture a mdoel.json file following the steps below. You can send the log to me using private message. 

     

    - Logon to the webui (http://192.168.5.1 ) as an administrator
    - Navigate to URL http://192.168.5.1/model.json via the same browser window
    - Capture the results (by selecting all + copy) and send it back

     

    If you haven't done a factory reset, please give it a try to see whether it makes any differences.

     

    Thanks
