I cannot turn on wifi… the slider for on/off is greyed out.It won't let me turn it on to search for WIFI signal.
Its software is of version 6.1.3(10B329)
Modem Firmware: 3.4.03
I have tried pressing the home button along with the restart button and it didn't work.
I have also gone through the Go to Settings>General>Reset>Reset Network Settings phase and Reset All and it's still not working.
What shall I do?
