After updating to Android 9, problems started connecting to Wifi. When the connection is active, the network is arbitrarily disconnected and when the connection is repeated, an error occurs, the network disappears, reappears, the connection is on and disappears again and so several times. I also found a slower speed of the Internet connection via WIFI several times.
