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...

This is happening to me as well.

Firmware Version: EC25AFFDR07A09M4G

Peaks correspond to LINK DOWN, valleys to +/- 30 from LINK UP
Could you please confirm which carrier's SIM you are using, Verizon?
Thanks
I am also having the same exact issue, works fine plugged into a laptop. As soon as i plug into my sonicwall or other routing devices it drops out. updated firmware, reset to default. Doesnt work in bridged or router mode.
I did just find if i plug the LM1200 into a TP link Archer 750 it works just fine. I can then plug my Sonicwall into it and it works through the lan fine. So there seems to be something going on with some kind of port security or buggy kind of issue on the port on the lm1200??
Could you please detail how you connect the 2 different routers? Just connect them to LM1200 LAN port and one is working and one is not working?
Please provide Sonicwall's model.

I am using a SonicWALL TZ370. I am connecting dircetly to the WAN port with a CAT6 patch cable. When it is plugged in directly to my pc, or the TP-Link Archer 750 is works as it should. When plugged into the Sonicwall TZ370 the following is what happens.
1. The device pulls a DHCP address from the Netgear LM1200
2. I can ping out to the internet 8.8.8.8, google.com for about 6-8 packets and then the connection drops
3. The ethernet connections light goes off and pings begin to fail
4. After a period of time the connection light comes back on and pings resume for 6-8 packets, then it drops again.
5. I also notice the Sonicwall pulls another DHCP address from Verizon each time the connection cycles.
I'm not sure if this is a LTE problem or a Netgear problem, but either way its not working like it should.
