Good point about offending devices that may be contributing to the problem.. I did see on the Netgear forums that people with some Samsung Smart TV's and Wifi Sensors indicated that they saw typical problems go away when they removed these devices from their network. I've tried doing this at time of problem occurrence by powering down suspect devices and waiting a few hours to see if things improve -- they didn't I've also left some of those devices that I suspected out of the network for now by wiping their Wifi settings so they don't connect to the network.
It traditionally doesn't recover just by removing the offending device, you need to reboot the network and leave the device off as you mentioned to fully rule them out.
