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...
Popping on here to say that I was having similar issues. I'm on Verizon - also using a Netgear AirCard Antenna to supplement my cellular signal signal as I live in a state park - so relatively rural.
Seemed to me to be an intermittent issue, especially when several devices connected to the network. I am solely using the 4G LTE connection, no failover from hardwire. I'm using a TP-Link Archer A7 router as well.
Changing the keepalive setting didn't seem to make a difference but setting the modem to router mode has. Only have one question, how much data does the KeepAlive use? Like most of us I am throttled after xGB, and I'm a little alarmed to see when I connect to the modem manager that the device has supposedly used 1.7 GB in the past 25 mins. I'm continuing to set up devices, so I likely think that they are just syncing with my cloud services, etc. Just wanted to check to make sure that I don't need to readjust the KeepAlive. Let me know if I can be of any assistance in any way!
My keep alive was already set at the minimal interval of 1 minute. I checked this all again and added the address 8.8.8.8, and google.com to ping. The process is still the same, as soon as i plug my sonicwall in the port pulls a dhcp address and then the LM1200 wan port shuts down. Rendering the connection useless. So I then uplug the firewall and plug in my laptop. The port comes back up and I can pull another DHCP address from Verizon and surf the net without issue. Why does this seem to be happening with wan ports on routing devices?
There are a lot of post here in this forum of people having similiar issues across multiple devices.

Please make sure you connect your sonicwall to the LAN port of the LM1200. The WAN port on LM1200 is for connecting your home broadband.
Thanks
John,
It is connected to the LAN port on the LM1200 to the WAN port on the SonicWALL, sorry for the confusion. The WAN port on the LM1200 will not be used as this is a mobile setup. So what do i do next? RMA the device or throw it in the trash and find another vendor? Cut my losses now?
Any new resolutions to this issue?
