Well I took the plunge and upgraded to 41712 firmware and got everything set back up. Running 2 AX92U in Aimesh mode with wireless backhaul on 5ghz-2. So far everything is working flawlessly, I got my fast speeds back on wifi and no drop outs yet. Fingers crossed I don't have to mess with it again. If everything is good from here on out I'll be more hesitant with the next firmware release. I'll update post again after I get to stress test this weekend with show streaming ect.
