M6 PRO Wifi Signal Dropping Out

Ok, I understand, like you had mentioned above it could be due to the update that was installed. However, I was wondering if you try a few short mini test. By reducing the amount of wifi devices that is connected to it, for example 1 or 2 then after 20 or 30 minutes connect your other 3rd and 4th devices. What I'm looking out for is, that your M6 Pro router "processing chip" or other components inside, your router, since the update was installed, might be generating "heat instability" due to the amount of connected wifi devices connected to it, eg work load on the router. Basically your trying to narrow down, what is causing the problem of the wifi dropping off.
