I readed this thread:



My iOs 6.0 device followed AussieMatty's method:


"Go to settings


Turn off blue tooth


Go into general settings - Mobile/cellular data


Turn off mobile/cellular data and 3G


Go back to general settings and go to reset menu


Reset network settings


After it reboots - Do a soft reboot (press and hold home and power button for 10 seconds)


After reloads go to settings and check if your wifi has 'ungreyed' itself! Worked for me!!!"



For my experience, turn off mobile/cellular data &3g is not necessary,

you can turn it on or off as you like.


There are 3 possible results after soft-reboot:

1.Still greyest-out.

2.WiFi icon switching enable, but can't find any AP.

3.WiFi become normal.


If 1 or 2 happened, just repeat the process any pray.

For me, the "normal WiFi" possibility is about 20% .


Every time it recovered,

it can behaved normal maybe 10 minutes/several hours,

then greyed-out or fail in searching AP again.


It's frustrated ! Oh my god!


Put the device in the refrigerator 10 minutes is also a temporary solution,

but this method only keeps normal <20 minutes for me.  :(
