RBRE960 after power outage only 50-55 will re connect

I have a 1940 house that has plaster and fiber walls the stage in between plaster and lath and drywall it is 94 ft wide and 30 ft deep as well as wood and aluminum siding ....that is the way was when i got it

the RBR is in the center of the house and that gives WiFi to most of the left side of house but i have a large fish tank and a few walls that block to the right so that is RBS#1 is on the far side of the house  about 35 ft away and that could be switch to wireless back haul but i have the wire

the RBS#2 is 60ish feet away in a shed in my back yard so my wife can use the WiFi and so I can use some WiFi cameras to keep an eye on my back yard 

that is connected using a set of TP-Link MC220L | Gigabit SFP to RJ45 Fiber Media Converter tplink and one of the first things I remove when trouble shooting 

WiFi coverage is good throughout the house  I can have a bank of three switches and one will reconnect and the other 2 will stay blinking or 2 will reconnect and one will stay blinking until I remove/reboot some other device or even 2 smart plugs in the same room as the RBR  it seams totally random as to what devices connect and what don't

neighbors near by 5 in the center of my house the only WiFi I get is my SSID on the left of the house I get 3 plus my 2 SSID on the right I get a different 2 as well as my 2    when I go out side I get about 8 plus my 2 depending on the location in my yard

as far as channels auto for the 2.4 and 48 g
