My 2.4 GHz WiFi keeps dropping out, I need to enter router settings; turn off and on 2.4 GHz access point for it to work again. The access point appears in SSID lists but after trying to connect to it, it disconnects instantly and disappears from the list or sometimes it doesn't show up at all. There is no such problem with 5 GHz. It happens randomly, sometimes after a day, sometimes after a week. My IoT devices stop functioning.
Smart connect is disabled, Channel and width on AUTO, transmit power on HIGH. Not sure how I can debug this problem.
