Satellite Wifi drops connection with all devices, but wired connection is fine.

SETUP: CBK752 — Orbi WiFi 6 DOCSIS 3.1 Mesh WiFi System with Built-in Cable Modem (1) Orbi Cable Modem Router (CBR750) + (1) Orbi Satellite (RBS750)

Setup in a 3200 Sq Ft House, satellite and router are opposite ends of the hours, like 70 ft apart and 4 walls. So not interference. I ran CAT6 myself and terminated the ends, they are fine. Only direct wifi is broadcast by the printer in same room and a low stength "2.4G Extender" from neighbor that is rarely visible. Firmware V4.6.3.16_2.0.51 Router, V4.6.3.16 Satellite. Armor off, 20/40 Mhz coexist off, short preamble. 

PROBLEM: My issues is that the Satellite is located within my office, I have the wifi dropping out 3-20 times a day as I am working, tried to connect to main (not close enough for any usable speed)

TRIED: I ran through all the recommended settings changes from the many threads here, didnt help. I now have a wired connection for my computer to the satellite, no issues at all for a week on the computer but Echo, Apple Watch, Samsung TV, iPad, and iPhone keep dropping still, so it isn't the Satellite losing connection from the backhaul cable. I have no degredation in speed hardwired to the Satellite while the wireless is having issues.

Is this just a defenctive satellite? No issues with the router.
