WIFI disabled - Greyed out since iOS 7 update on iphone 4s

Oh, and he says he's having the issue with his Galaxy S3---NOT!

I am also facing same problem . It is a pure software issue . It has nothing to do with hardware. Apple should remove this wifi bug from this firmware . It is not launch a untested software update . I heard some saying that this problem is in one or two case but tell I know many people are facing this problem . Apple should ask its team to work for solution of this wifi bug.

I had exactly the same problem. I tried everything - resetting network settings, restore etc.

My iPhone 4s was also out of warranty but I took it into the Apple Store anyway. The guy plugged it into a computer and diagnosed that my wifi chip was dodgy and that *coincidentally* (he looked a bit chasten) updating to iOS 7 had pushed it over the edge. My bluetooth was also fine by the way, so I think he was right about that.

I was lucky and found out that because I live within the EU, they are obligated to replace my phone if it breaks within two years of purchase. Of course, this only applies in the store where you bought it. My advice would be to take it in and see what they say.

Based on my experience I don't think it can be fixed with an update, it does seem to be an underlying fault in the phone itself.

I hope this helps. Best of luck with your phones.

How's the 3rd party repair going?

they've had it for a couple of days for diagnostics, haven't gotten to it yet. will definitely post here when i have the outcome.

If it's a pure software bug in iOS 7 how do you explain this thread: Does ios 6.1.3 wifi issues get solved in next update?

3rd party vendor says they can't repair it

Did they give any indication if it's something a firmware or software update could fix or did they say the hardware is beyond repair?

They said the only thing they could try was a full wipe/ restore of the phone, and that might not work. I had already tried that a couple of times. So it's a hardware issue triggered by a software update. This matches the explanation I got at the 'genius' bar.

If someone said this is hardware issue, then please explain why i can still see the wifi MAC address !!

I suggest you take yours to a third party repair for diagnosis, as it's not clear that we have the same malfunction. Good luck!

i try the hair drier method and it works (touch wood)

- shutdown then use a hair drier to blow hot air (about 10 cm apart between them) to the eairphone hole for about 3 minute

- after 3 minute, i power on the Iphone

- once login i am able to change the wifi button and able to see my wifi, but somehow, it is not conecting.

- I then do a restore, somehow the phone failed and goes in to "recovery mode" and i do a restore from there onwards.

- once the phone was restored to factory default, i restore from icloud all my data.

------ currently is still doing restoring all my apps about 8G
