Q: Wifi greyed out on iphone 4s with ios 7

- reset network settings

- back up and restore. test issue before restoring back up.

- get phone replaced

in that order

IPhone 4S is still working perfectly after the heat up and freeze fix solution. Has been so for about 2 weeks now.

Fingers crossed, that I'll get lucky, and it will remain functional for the rest of its life

Makes me extremely hesitant to ever carry out another update on my 4s.

Good to hear that the heat and freeze fix works for you also.

It doesn't worry me if I have to repeat the heat and freeze fix again

Just so long as my IPhone 4S will continue to work, I'm as happy as  can be!

Hey!

Thank you so much for the heat thing advice. It worked for my iphone 4s!!

I was afraid my wifi wouldn't get fixed, and that I had to learn how to live without it... However, I think my problem didn't come after ios 7 update... I updated it at least 2 months ago. 

Now, let's see how long it will last for. Hope it's fixed forever.

Glad to hear that the heat and freeze has also worked for you.

Will be interesting to see how long the fix works. Like you I hope it's a forever fix.

Enjoy useing you now fixed phone! :-)

Anyone tried the new iOS 7.0.6 to see if there is any improvement? My wifi is still working so I can't really check

An iOS update will not repair a hardware problem.

iOS: Wi-Fi settings grayed out or dim - Support - Apple

..It's not a hardware problem.

I finally got around to trying the blowdryer fix and was pleasantly suprised to see it suceeded. Qustion now is for how long. Fingers crossed.

As for 7.06 there is 0% chance of me updating and losing my wifi again.

Explain to me how a blowdryer can fix software bugs.

This is a hardware issue with the wi-fi chip being too sensitive to heat.  That's why the hairdyer/freezer trick 'works'.  You're manipulating the wi-fi chip hardware with the temperature variances.

Trust me this works! I just did it myself and my wifi is back on.

I took a hairdryer to the earpiece until the phone said temperature too hot, power off immediately, put the phone in the freezer for 10 minutes and then take it out and let it set for another 10 minutes. Turn it back on, go to general settings>reset>reset network settings. When the phone comes back on, your wifi will be back up and running. It is a weird experience, but it works

Hi: I Did the blowdryer-freezer trick and it worked.  Does anybody knows if updating to iOS 7.0.6 greyes out the wifi again ??

Unless I had had a real need to upgrade to IOS 7.0.6, I just wouldn't risk it.  "Let sleeping dogs lye" and all that.

I'm warped that,( like you) the heat and freeze fixed worked.

There's an old saying

If it's not f***, don't fix it!       :-)

If your iPhone is out of warranty, have a go at the heat and freeze fix.

It's been a total success for tons of iPhone users, and that includes me.

My iPhone 4S (that had problems with wifi, bluetooth and battery drain issues) is now working like a dream since doing the heat and freeze fix.

It may, or may not be a permanent fix. But even if it's not a permanent fix all that needs to be done is spend half an hour to repeat the heat and freeze again to have the phone up and running perfectly again.

Nothing ventured, nothing gained.

As for 7.06 there is 0% chance of me updating and losing my wifi again.

Ditto that!

Hears the link again on how to fix wifi, bluetooth and battery drain problems.

And AGAIN!

It's a "D.I.Y"  YouTube video that  tells you how to carry out  the " heat and freeze" fix

It's not my video and I make absolutely NOTHING! from sharing the link

All I'm doing, in providing the link, is trying to help people.
