Wifi keeps disconnecting. 3rd generation controller. Piece of crap

I tried all sorts of connecting, disconnecting, resetting wifi. Keeps going offline. Super annoying. Piece of crap. I have so many wifi devices at home. None of them goes offline like this for no reason. I read their support article. They say to use this version of iphone, that version of ipad. Seperate your wifi if it is 5mhz. Etc etc. none of the wifi devices at home requires such complicated wifi setup. Piece of crap
