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...
I just got my LM1200 earlier this week and would like to join the growing list of people having this same problem. I want to connect the LM1200 in bridge mode to my pfSense firewall (core2duo with Intel quad gigabit card). I have Verizon service with the card the local store recommended when I showed them my LM1200.
First day: I hooked everything up accessed the LM1200 via web interface at 192.168.5.1 using a PC through my pfSense, got a connection after a couple failed attempts and used it for about 4 hours until I was done, and manually disconnected. Ever after: when I connect the LM1200, it quickly says it is connected, then cycles the link (link light down then up after several seconds), then says disconnected and cycles the link again. Every now and then, it will be up long enough to get maybe 3 or 4 pings to 8.8.8.8, but that is rare.
I can hook directly to a single computer just fine. When I connected to a single computer and let it work for a few minutes, then swung the ethernet cable over to the pfSense, I got good pings for about 20 or 30 seconds, then the cell connection dropped again.
I have already disabled IPv6 on all of my PCs, pfSense and LM1200 - I avoid using IPv6 anyway - just call me old-school. I will certainly try router mode tonight in hopes of getting my whole network online.
Let me know if I can provide anything to contribute to a solution - I really want this to work in bridge mode in hopes that at I could get at least some access into my network from outside. (I used to host several web sites and frequently remote into my home network from outside util I moved - I'm sure web-hosting is out of the picture over consumer-level cell, but bridge mode is what makes the most sense to use for a router/firewall anyway)
Also, thank you to everyone who has been contributing. This being my first venture into cell data (since comcast backed out after telling me they could hook me up), I was starting to think I missed some fine print in some verizon usage clause or just didn't understand how the LM1200 was supposed to work.

Thanks for the detailed information. Based on the discussion here, we know that pfsense can trigger the disconnection issue easily, but the disconnection initiated on the Network side. Really need to get the network logs to find out why. We could reproduce the same issue with other Netgear fixed wireless products on Verizon network. Even with LM1200, we can see that the issue happens intermittently, but when it happens, the link will keep resetting for a while before it finally gets stable.
Thanks
