LM1200 repeatedly dropping link

I recently purchased an LM1200-100NAS to serve as an LTE failover connection for my homelab and noticed a strange issue while setting up my pfSense-based router to use the LM1200 as a secondary WAN c...

Same problem.  

 

I am plugging into WAN2 on UDMP.

 

LN1200 LAN light goes on and then off.. 

 

I plug LM1200 into my computer and it connects fine.

 

I have tried EVERYTHING I could think of.  I disabled IPv6.  I upgraded firmware.  I plugged into WAN1.  Nothing worked.

 

I need a LTE backup for my UDMP.  This should have been EASY!!!!  

 

Any help would be appreciated.  I also have put in a support request.  I hope I get some kind of response to this.

 

I believe this is a LM1200 issue and NOT the UDMP.

 

Thank You,

    I am also having the same issues with the LM1200 on Verizon but with a Tplink router.

    I was able to confirm with VZW that there should not be any issue connecting a DHCP router as the hotspot plan does not limit connections. I also have a support ticket open with Tplink to review the router logs showing the disconnect and reconnect cycling.

    However, I even tried an older Actiontec router left over from my previous ISP and that had the same issues once I connected multiple devices. This only seems to occur if the modem is connected to a router or hub. If it's a direct 1:1 connection, be it game console, pc or laptop, it works fine.

      Thanks for checking with Verizon.  So we have pretty much ruled out everythign but the LM1200.  I wonder if anyone has tried the Nighthawk M1 Moble LTE hotspot MR1100-100NAS?  We need Netgear to fix this issue or I have to send this back.  We are using this as the backup Internet in the case there is an outage with our wired carrier.

        For reporting the LM1200 dropping link issue when connecting with a router as client, please check the the device has been upgraded to the latest FW release:

        App Version: NTG9X07C_20.06.09.00

        If the issue still happens, please report the following information:

        1. LM1200 is set as Router mode or Bridge Mode

        2. Carrier Name

        3. APN name

        4. IP Type

        5. Is LM1200 connecting to WAN backhaul

        6. Router client brand and model
