After Marshmallow update . Wifi is super slow on 2.4 Ghz, fine on 5 Ghz and now bluetooth stopped working. If I enable wifi verbose logging or switch dhcp client to lollipop , then wifi works fine on 2.4 Ghz.However bluetooth simply will not turn on anymore. Not only that , if I look into battery usage , bluetooth is hogging battery like never before. . Can we expect another update to fix these issues ?
