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...
So just thought I would pass this along. I ended up returning the LM1200 due to the connection issues. I bought another vendors equipent but also expierenced some similar, albiet not as extreme connection issues, but ocasionally I would go through cycles where I was disconnected and reconnected. I noticed that I was getting a IPv4 Address and a IPv6 address. After trying some different things, I finally set the protocol type to IPv4 ONLY. Ever since I have done this, the connection has been 100% stable, I change it back to IPv4+IPv6 and i have sporadic connection issues again. There seems to be something weird happeneing with Verizon when getting a IPv4 and IPv6 address.
Since I have already returned my LM1200, I don't recall if disabling IPv6 was an option.

This is an important information. Thanks for your feedback.
As our investigation shows, even though the device settings can cause the issue, eventually, the issue happens on the Verizon network side since the network intitiates the disconnection and the issue happens intermittently.
Thanks
