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

I had same problem .I tried everything and nothing is   work. Until I opened the phone and heated up the WI-FI chip with a hair drier for couple of minutes and now is working.

I had this problem with my 4S. I booked an appointment at the genius bar and they changed the phone for a new one without quibble (only 8 days were left on my warranty!)

Now after having the new phone for just over 2 weeks the same problem has occured - wifi button greyed out!

I will be taking this phone back and demanding a refund or at he very least a new phone with travel and parking fee compensation.

Apple has gone way down in my estimation!

See my post November 5th. Its a hardware problem.   Get someone to fit a new wi-fi chip. problem solved.  Costs about £35.00 in Wales.

Hi I put my phone in the freezer as well, it killed my battery but when I charged it and turned it back on, the wi fi was green again!

the freezer method sounds crazy but it really works!

Apple should be punished and everyone should "STOP" buying their ****** stuff. They chose to blame this issue to the broken hardware(that's the end result caused by ""APPLE""), but not telling us what the root cause is. I can't believe how contemptible they are. I have called Asia apple care and they told me they didn't see this issue reported in Asia and they won't acknowledge any evidence from apple forum or websites. I was ****** and told them that if I paid the stupid fee, can you promise me you refund my fee if the new phone exhibits the same problem after the upgrade? They said they can't promise that and they can only make another replacement if it happens. ***. If they are so confident with their **** phone/iOS7, why can't they promise that? Then I called US apple care. I sent them the link about this problem in apple forum and she told me "I do want to let you know that the likelihood of heat causing the wifi to be grayed out is extremely slim.". I don't know if they are all blind or ********. Even with so many postings, they can still ignore it and educate their staff to talk this BS. I really want to know if this issue happens to their own phone, what would they react??? Believe this BS themselves!~ ? APPLE, please stop wasting our time. I don't want to try fixing your **** phone myself!!!

I was the same but try the freezer solution

It worked for me

You got nothing to loose

I am having the same issue. 4s worked fine until I upgraded to IOS7. I have reset the phone multiple times without success. The wi-fi stays greyed out and does not work.

Interestingly, putting  it in the freezer for 2-3 minutes does the trick. Wifi will work for a few hours. How long do I try this? Who knows. Frustrating to say the least. Let's see what the genius people say tomorrow!!

You will get a replacment because they guarantee your device for 90 days, but you won't be getting compensation for anything else, since they offer mail in repair options. I promise you that.

Since I updated to IOS7.0.3 my iPhone 4s WIFI has greyed out too. I tried contacting apple support Iindia for the issue and they have a standard reply to fix it "Please try resoring your phone through iTunes" WHICH DOES NOT RESOLVE THE PROBLEM. About last week I accidentally drained battery out completely and when I charged it the Wifi was back. It worked for about an hour and then again greyed out. Next time I purposefully let my battery drain out - charge it to see wether the WIFI comes back and it did for 30 mins and then again greyed out. I beleive its a IOS 7.0.3 issue and hope Apple fixes it.

The freezer method does work, but the issue is what happens after. Your wifi does turn on, but only for a short period of time.

Well, something wierd just happened. My WiFi has now started to work perfectly, just as my new WiFi chip was to be delivered tommorow. The phone had its battery drained, so I charged it. When I came to turn it on, WiFi was back! Maybe this could be a fix?

It won't last!  Just get your wifi chip replaced, that's the ONLY solution that really works!

I had the same problem with ios 7.0.3 and an iPhone 4s and after I watched a thousand youtube tutorials how to fix it, suddenly 1 worked!! just blow dry your iPhone until it is really hot and than reset the network settings, after it restarted everything is fine again!!

I'm soo happy!!

Hopefully it works for you too!!

Apple has finally recognized there indeed is a problem

http://support.apple.com/kb/ts1559

Everyone, please refer to this Apple knowledgebase article when claiming support.

Let us know your experiences!!

Sorry, this article isn't new. Note at the bottom where it says:

"If you are still unable to turn Wi-Fi on, please contact Apple for support and service options."

Your warranty status still dictates your service options. No warranty = fee for repair.
