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 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.

4. IP Type: IPV4V6 setting in APN. Both IPv4 and IPv6 IP addresses are issued once the connection stabilizes. The router interface is configured for DHCP for IPv4 and SLAAC for IPv6.

I just tested in BRIDGE mode with my Mac and I am seeing the same drop outs. My main problem is getting this device to work with a Unifi Dream Machine Pro.

Are we sure this is not Verizon? It seems odd that for me in Router mode it works fine. When I switch to Bridged mode and I get an initial connection the link light goes off. It feels like Verizon is rejecting the device. But who knows...
Just bought my LM1200 yesterday and just noticed this issue. It happens just about every 2 hours (T-Mobile DHCP lease time?). I've attached a screenshot of the log entries from my router.
1. Bridge Mode
2. T-Mobile
3. T Mobile (fast.t-mobile.com)
4. IPv4
5. Is LM1200 connecting to WAN backhaul - No
6. Mikrotik RB5009
7. N/A
I this is for a mobile setup that needs to be connected through the sonicwall to a vpn, I really need to get this operational if possible.
Is there anything I can do to help you out? provide a packet capture? provide a log of some sort?
