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.  :(
