Nighthawk Mesh Wifi 6 Router MR60 losing connection to 2.4 devices

I have the same problem with my Mr60 system and 2 MS60 satellites. I actually read it was best to download the previous version of the firmware, so I tried that. It worked for a few days, but I still get disconnects. I've tried port forwarding and reserving certain ports for my 2.4ghz devices that I need daily (smart bulbs, security cameras, smart ceiling fans w/lights), but nothing seems to permanently fix the issue. I had problems like this on my Nighthawk R6000 and R6000 as well. You'd think I'd learn my lesson and stop buying Netgear. I even have 5 ARLO Pro and Ultra cameras, and even they don't play well with the family, and most are wired (smart bases / hubs are also wired). These are expensive units, fix it Netgear!
