I've been having an issue with my note 10.1 reconnecting to the wifi after it has been asleep for a while. I don't want the wifi on while it sleeps so I can conserve battery life while I'm not using it., so I set it to have the wifi only sleep when plugged in. I have also tried never keep wifi on during sleep but when I do either of these I alway end up having to disconnect the wifi and reconnect the wifi to get the Internet back working. Does anyone know what might be causing this issue. I have the wifi only galaxy note 10.1 by the way.
