wifi greyed out iphone 4s

Turn off your phone. Use a blow dryer and point at the headphone jack for about a minute until it's hot. Let cool and turn phone back on. It should work again. Note that mine worked for 2 days and stopped again. I did the blow dryer again and also downloaded the most recent IOS 7 update and it has been working normal ever since.

If you know how to disassemble your phone, you heat the wifi chip directly... That seems to be a permanent fix... There are lots of videos on youtube now, you just need the right tool... Just heat the wifi chip directly, no need to replace anything... Just cover the other parts...

No, it is not. Sooner or later it will fail again. I have tried the direct heating twice and it lasted for maybe 3 weeks. If one is lucky it can hold for maybe few months but there is no permanent fix but replacing the chip. Ive tried this bacause for me phone without wifi is a junk but I killed the phone. It is really not easy to replace the chip so I don't recommend this.

Mine if i'm not mistaken is about 3-4 months now...

Edit: i totally agree with you, an iphone without wifi is a junk...

Hi Birjest, I have the same issues with the grey out of my 4S, when it first started was the wifi is on and then goes off and can not get it back no matter how hard you press the wifi button for some time, and then comes back again.I turn the power off and on, then the wifi starts again for few time. and then it turns grey and can never comes back. Did you said you get an replacement phone after a year warranty out ? If so, what did you plain to the apply support to get the new phone? My 4s is 2.5 years old and also out out warranty and was traveling in HK when this wifi grey out. The HK apply can do nothing about the issue. Thank you for your response. John

I solved this problem and it cost me nothing.

My issue was that the wifi was greyed out and I could not tap it on, it was like the option had frozen.

I tried all of the resets, rebooting wifi router and the rest, none of these solutions worked for me.

Incredibly, to my surprise the hairdryer solution worked. I was very doubtful so did this last, but it did the trick.

I cannot imagine Apple suggesting the hair dryer as the solution to fixing it, I mean the liability, as inevitably someone will not follow the simple instructions and manage to melt their phone and burn down their house. Plus sounds crazy, what kind of multi billion dollar company would tell you do that?

I cannot imagine it either, as Apple has not recommended the 'hair dryer method' to anyone.

I would be shocked if they did. It works and my phone has been fine. Did you also try it?

No, I haven't had this issue, nor would I use such a method since it would void my warranty.

Agreed, I don't think I would try it either if I didn't have the issue nor the warranty.

If I had the issue and not a warranty, and didn't wish to shell out for a repair that the Apple IOS caused in the first place, I would be inclined to try it.

OMG it worked thank you so much!! 🙂

here re is the solution which. Worked for me...make it deep discharge and let it be switch off automatically and leave it for 1-2hour then start it...its work for me

OK so how come apple has not come up with a reset that shuts down the phone like a deep battery cycle or an over heat shout down

obviously the problem is programing and how come they don't fix it, i have gong true 3 up dates and it still happens. I just preformed the over heat repair for the 8th time. its hard in the screen. I had to unlock my phone to use local provider Sim and that ends my warranty.so replacement is not an option. what will they do to fix this problem the 4s has ?

p.s. no i can't go to a local apple store
