Modem => Firewalla Gold SE (router mode) => TP-Link Deco XE200 (AP-mode) requires daily restarts

At least daily, and sometimes more than once a day, my network goes offline, and I have to restart the Gold SE, or modem to restore functionality.

My full setup is as follows:

Modem => Firewalla Gold SE (router mode) => TP-Link Deco XE200 (AP-mode) <- wireless backhaul-> XE200

I am running the FWG-SE in router mode. I did not see XE-200 listed anywhere below. Should I be trying other modes?

https://help.firewalla.com/hc/en-us/articles/360047098773-Router-Compatibility-Simple-and-DHCP-Modem-Legacy

Is there some standardized way to upload+report logs from FWG-SE that could be used for debug?

I used to run my network like so with the same modem and didn't experience nearly the same level of problems as I am now with FWG-SE.

Modem => Ubiquiti UDM SE => UI APs
Modem => XE-200 mesh in router mode

    The compatibility article only applies to simple/DHCP mode, and it does not apply to router mode. 

    For your problem, please look at this article https://help.firewalla.com/hc/en-us/articles/360053534593-How-do-I-debug-network-connectivity-issues first, and identify the problem location first

    Thanks

    1. cables are good, all the lights are on and blinking at the expected speeds for both the WAN and three LAN ports
    2. I am unable to connect via the app when the system is in the failed state. While wifi is on, when the system fails, I get the "Firewalla is offline" dialogue. Disconnecting my phone from wifi and re-opening the app to attempt to connect via Bluetooth I get "Firewalla box is unreachable"
    3. When the system is in the failed state, I am unable to ping the box from my machine connected over ethernet LAN to FWG-SE (with wifi turned off)
    amastro@amastro-mbp ~ % ping fire.walla
    ping: cannot resolve fire.walla: Unknown host

    After unplugging and re-plugging FWG-SW the system comes back up, and I can ping the box over LAN with wifi off. Rebooting FWG-SE only (not the modem or mesh APs) causes wifi and internet access to be restored.

    amastro@amastro-mbp ~ % ping fire.walla

    Can you also double-check if the USB-C power supply used is the supplied by us?
