Extensive data loss after new gear

Hi
I installed “another branded” AP, 1 meter below a Groove
I now get randomly all my Groove APs disconnected ALL AT ONCE with the “extensive data loss” message

I’ve lowered the “other brand” AP db and set adaptive noise to “ap and client mode” on the Mikrotik

They are on Channel 1 (Groove) and Channel 11 (the other one), both on 20mhz, near ZERO interference from other sources

What could be the issue? Too close between them? Or what?

Check the spectral scan. Maybe there is a measurable interference.

theres almost 0 interference… only the APs in groove (most of them at 1-50ms) get disconnected, ALL at once, like theres a “timeout” option or something, once or twice each hour drops, auto reconnects almost instantly.

¿?

This case I have between two hap lite devices in wds mode. They never last more than 4 hours connected. Ticket is opened for that at mikrotik. For long time already, we swap few emails about time to time but there is still no solution.
