I have had many problems with wi-fi and bluetooth. My wi-fi and my bluetooth headset is disconnecting more often than in iOS 10. The product i am talkingt about is the iPad Air 2. It disconnects from wi-fi every 45 minutes and with my bluetooth headset every hour. And i have changed my wi-fi to 5ghz so it does not make issues with 2.4ghz bluetooth band. So is it a change in the software so it sends less power to the network card so it can save power ? But makes the conmection less stable?
