I use a Firewalla Gold SE. I used a Linksys MX4300 for troubleshooting. It cannot connect to the CM100 either.
I am not using port agregation

I have tried both LAN ports multiple times with multiple cables.
The CM1100 was power cycled multiple times for 30+ seconds. I've done that with and without the router connected
I don't think it's an issue with the router as it can connect through the cellular modem.
For clarity, neither the Firewalla Gold nor the MX4300 work with the CM1100. Both work with the cellular modem. A laptop connected directly to the CM1100 works.
