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...
Using verizon here. I am experiencing the same issues in this thread. The disconnects between LM1200 LAN port and router port are a layer 2 issue correct? Link up/down/up/down. Why does the (MAC) layer 2 connection between the LM1200 change? What does that have to do with the Verizon wireless connection? I am using a edge router 4. For comparison, if I disconnect the coax from my cable modem, my modem and router are still connected layer 2.

If this is true, the issue discussed in the thread doesn't apply to your setup. The Verizon disconnection issue happens when using Verizon wireless network.
Thanks
- John, Apologies. I am not using a Verizon cable box, I am using a LM1200. I was attempting to draw comparison to another type of modem and the behavior when the service provider connection gets dropped. This might help eliminated confusion if the LM1200 LAN to router L2 connection remained persistent through provider connection dropouts. No other modem that I am aware of drops L2 link when the service provider connection drops.

It will pass the network assigned IP to your router. That is why when the wireless network disconnects the connection, the device will try to reconnect, refresh the IP and pass it to the router client.
Please try setting the device to Router mode to see whether it will help.
Thanks
