Is there any good news ????

FURRYe38 Really? Exactly which others did those solutions help? Seriously, who had their disconnect issues solved by what you suggested?

Those are just blind shots in the dark and just spreads confusion and doubt.

Disabling beamforming only helped with nest cams in the early 1.x series when netgear didn't have that basic feature working properly. It's had no impact on disconnect issues since then.

Fast Roaming? That's an AP-side feature, not known to the clients. It's not going to change anything, it's not 802.11r. It would only impact roaming anyway.

Daily Chaining? What? At best that would be a performance only feature. Nothing to do with disconnects.

Disabling Mu-MIMO support? Again, that's performance related. And, if you had to disable that feature, you'd want to return the unit. That's a core feature of modern wifi. That's like saying "see if welding the trunk closed makes the car ride more smoothly". If it does, you still have a major problem.

Stop with the confusion and illogical suggestions!
