Deco S4 AP mode mesh random crashes
I have 2 Deco's for wifi access connected in a mesh, AP mode. They are 100+ feet apart and in seperate metal buildings (no way for wifi backhaul). I have them connected as you see below - not with a dedicated ethernet cable between them for dedicated backhaul, but using existing ethernet network.
This works fine, except every once in a while they go face down and give the orange "I'm dead" light. I power off both, and power up the main first, then the 2nd and all comes back up fine. These crashes may be few days apart or even weeks. Fully patched up firmware.
A) Is this an inappropriate use of backhaul and should I just make each its own independent AP with exact same network SSID/password since they have no chance of interfering? I wanted to avoid that in case I add more satellites later...
B) Is there a newer/better TP-link product to do what I want below?
I need the Barracuda doing DHCP so definitely need the wifi AP mode only.
thanks,

p.s. Here is the product I'm talking about: https://smile.amazon.com/gp/product/B084GTH5LL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
