I was watching something online on my Tab S2 and suddenly the video paused, initially I thought it was buffering but later realised Wi-Fi disconnected yes and won't reconnect. Rebooted the tablet but no luck. Also rebooted Fritzbox. I use the wireless security settings where new wireless devices are not allowed, only known one's. Has anyone ever had this issue? I've already checked that Rab S2 MAC is still there in m own devices and I've already tried removing and re adding it. All other known devices are working ok.
