Wifi authentication issues and bluetooth fails

[Mumz]

Wifi authentication issues are always a problem even in my home where everything else is connected and there are no issues with any other devices connecting to the internet, but somehow the phone has issues and loses wifi connection. Restarting the phone everytime this happens is not a solution. From the start this phone has had issues with bluetooth connectivity. I have to restart the bluetooth to get it to connect almost every single time I want to use it. Restarting the phone and/or bluetooth everytime these issues happen is not a solution. Sony needs to fix these issues that apparently many many people are having instead of marking BS answers as "solutions" and closing the forums. This is a no-support and no-solution forum.

Dear,

  There are too many persons complained this issues for long time. No feedback from SONY, SONY seems to give up this phone.

One trick to replace reset. You can just turn on then off airplane mode. Then wifi and bluetooth can work well for a period of time.
