I have a Samsung Galaxy S5 gold and the wifi will connect and then disconnect every 10 to 15 sec. It is connected to my home network. My wife has the same phone and it does not have a problem with staying connected to the network nor does the computer I'm working with. As a side note my wife also has a Samsung tablet that has started to do the same thing (connect and the disconnect). I shut down the phone and pulled the battery to try to reset but did not work. Canceled the wifi connection and reconnected, did not seem to help. Any suggestions?
