iphone 4s wifi greyed out.

So probably best not to upgrade and if uou do, get in touch with Apple Care first to discuss your concerns. They may be the best people to advise you

Ok. So here is what I have found out. Apparently when we upgraded to the new operating system our wifi chip was on the way out and not working 100%. The geniuses I spoke to explained that when the upgrade happened the software recognised a not perfect piece of hardware and shut it down which begs the question.... Why did Apple not warn us not to upgrade our 4s phones as this was a likely outcome?

I've tried all the non invasive suggestions on this thread to no avail. On top of everything my 13 month old phone also has a dying battery. Rethinking my 15 year+ allegiance to Apple

It turns out the law simply states that you have the right to return an item for up to 6 years, if you can prove it has an inherent fault, present at the time of manufacture, and you would reasonably expect the item to last longer than 6 years

Apple may see the wifi chip defect as faulty. Certainly my battery and my wifi chip have failed within 13 months, which you wouldn't expect. Sadly I bought the phone in America so it's not covered

Does anyone get what is really going on here? Apple is now focused on production of a commodity, not on satisfying trivial groups of customers. This is what their bean counters tell them to do; ship out volume, don't worry if quality issues affect a million or so customers. Great short term thinking, but this is how great companies go rotten.

This is what I did and it worked...Download the Witness Driving app and overheat your 4s using the app with all settings enabled and make sure it is charging as well... it may take 1/2 hour or so (maybe longer)...after that let it cool down (I held mine out the car window while driving) and then just do a reset of all settings. It worked on mine and it also fixed the battery issue as well. It went almost a day before it dropped to 99%, just sitting (not being used). It heats up right by the wifi chip and when you are running video, nav and charging all at once it gets toasty...enough to do the trick. It's been fine for a week so far..... http://youtu.be/FBi7wkatyPQ

Hey, I had the same problem. I tried almost everything.

Finally IT WORKED.

I let my battery die fully, waited for about 10 minutes, then I recharged it and the wi-fi was active. It took me about 5 minutes for it to start working proparly. In the beggining it didn't find networks but aftre a couple of tries and waiting it finally found networks, connected and worked.

Hope it will stay this way!

Hope it works for you too!

Solution to wifi greyed out is to overheat your iPhone with a hair dryer until it turns itself off. Then it will start working a few hours later. This is the 4th time the hair dryer trick worked for me in two years. Google it to check.

Hi all,

After I've tried all the methods described on the web to make my wifi work again on my iPhone 4s, I gave a try this morning on the "hair-dryer method" (I was afraid initially to damage the whole thing), but IT WORKED PERFECTLY!!!! I don't know if in some days or weeks I'll have to do it again, but everything is working really fine now. Here is the link:

I have heated the iPhone for ~13 minutes, until I've got the meassed of "overheating". I've turned of the iPhone and let it to cool down for 30 minutes and everything is fine. Just do the heating slowly, and concentrate the hot air around the earphone jack, moving from time to time to the screen!

Apple knows that, and I'll definitely not buy another iPhone. It is a pity that after Steve Jobs passed away, Apple started to do these "small tricks" to make people to spend money in unecessary things. You should be ashamed!!!

I had the same problem with my 4s with the Wi-Fi button getting greyed out for no apparent reason. I read several posts that talked about heating it up and freezing it. (I didn't try those methods).

Anyway, I read a post, where a person just let their iphone battery go dead overnight and they said the Wi-Fi worked after they recharged. I thought that would never work, but UNBELIEVABLY I am on the Wi-Fi right now as I type.

Long story short - you probably don't have to overheat or freeze it to shut it down (might chance possible damage), just let the phone go dead and recharge and it will be up and running.

Regardless of this being a software or hardware fault, Apple need to own up and get this issue resolved very quickly !! The internet is crawling with unhappy iPhone users who cannot access their WiFi !!

... The Apple halo is falling !

I have an apple Iphone 4 8 gig CDMA from Verizon, model MD200LL/A running ios 7.0.4 (11B554a)

I have had greyed out wifi issues since the first installation of iOS 7. Sometimes it would come back. Now on 7.0.4 I cannot connect to wifi at all. The slide button is greyed out. I did the freezer method, didn't work. However, with the hair dryer overheating method, it did overheat, and then after reboot, it switched on wifi, and it found and connected to home wifi, and STAYED connected to wifi like glue. Supreme great wifi connection. For about 12 hours. By next morning it was greyed out again. I did this twice and both times, the newly found wifi was greyed out the next day. Now I'm not going to keep hair drying my iphone to make the wifi work, this is ridiculous. This iphone is way out of warranty, 3 years old etc.

I've heard people say they go to the apple store and they pay 130, or 160 British pounds (I'm in the USA) and they got a replacement. What will the apple store tell me if I take this iphone to them with the wifi problem? Is it $200 for a replacement? Is that a replacement going to be another 8gig 4? Or could I get a 4S at this point? The apple store is an hour away from me, just wondering what to expect if I go there and ask for help.

Everyone who overheated or battery-drained their phone to achieve wifi success, please indicate how long it STAYED THAT WAY. Was it short lived?

UPDATE, following GonnaGoDroid request :-)

I've overheated my iPhone 4S, the wifi worked for 2 days, and now it is greyed out again. I won't do it again as I can still make calls and listen to music, but I am definitely abandoning iPhones. It seems after Steve Jobs passed away, Apple lost the track (again). This is pretty clear in the constant number of stupid updates we receive for the iPhone and for the Mac after these new OS versions. It is a pity!!!

I have wifi issue on my iPhone 4S too. But I have changed my phone to Sony. For me, iDevices are high-end devices on market but why there is issue like this. This is horrible situation I have ever experienced. What can I do without wifi ? Even downloading app with size more than 100mb. That's why I decide to dump my iPhone away LoL. No more iDevices. Sorry apple

I had the same problem on my daugther's iphone 45. I stopped by the Apple store and they offered an exchange for $200 but I had to book an apointement. The next day my daughter dropped the phone on the floor and it worked fine since. I guess it needed a little shaking

Contact the apple store first or apple help http://www.apple.com/support/contact

Apple explained to me that the new software on upgrade has detected an issue with the wifi and so closed it down but they have not admitted any hardware liability so it's very important for everyone to contact Apple and complain. Otherwise they won't acknowledge the problem.
