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

I have the same problem......as many others I have downloaded iOS7 and the problems started! I wish I have never done that.

I am very frustrated....no wifi ....no bluetooth..... and so many people with the same issue.... and no help from apple!

I would suggest everyone to "STOP" buying apple products. Very dissappointed with apple!!!!!

Okay so I recently posted that I was having the same issue & luckily thanks to Apple Care coverage until Feb I went through 2 replacements. With replacement #2 I didn't have patience to wait with turning on do not disturb and Airplane mode so I thought it was unsuccessful. I was also frustrated that my phone wasn't restoring & I thought I had lost my last iCloud back up... lets just say I was 5 seconds from throwing my phone at the wall.

Well with my 3rd replacement my wifi didn't go out until 2 days later in the middle of my restore. So that night after frustration and REFUSING for the 5th time in 4 days to wipe & restore I tried the method again..IT WORKED! I didn't think it would. Heres the thing though you have to let it sit in off mode & don't turn it right back on. SO heres what I did.

I turned on Airplane mode & Do not disturb then turned the phone off. I waited 30 minutes to be sure. It absolutely worked and so far no issues at all!!!!!!

What I understand is there is an issue with the iOS7 update & the network settings. It is registering that the network is unavailable within the software. As a result it is thinking it doesn't have wifi capabilities & isn't turning back on.

I have now successfully been running wifi for 3 days with no issue. If something happens that it quits working I will be sure to let you know & you better bet if it does in February I will be going elsewhere.

Guys - there is no fix to this problem. Just got out of an Apple store genius bar appointment. iOS 7 kills the wifi/blutooth chip. hardware failure. If you're out of warranty or don't have apple care or can't upgrade your phone you are out of luck. They know it's a 4S problem only. You upgrade to iOS7 at own risk. Pretty big failure for apple.... IMHO

Bought my iphone 4s one and half year ago ......so of course I am out of warranty .....just can not believe I was so stupid to download ios7 ..... but I thought I could trust their suggestion to do it.....now my phone is ****** .... 628 euro after 1 1/2 years.....bustards....

I also had the same issue. Tried most of the suggested solutions. Finished up taking my 4S a part and lucky me I had a hot air soldering iron. So I did heat up the soldering of the WIFI chip and also the chip itself cooled it down for a while and reassembled it. Working fine so far. Keep fingers crossed.

So my wife's 4S has not had its wifi working for about a month. She updated it to IOS7 last night in an attempt to see if it solved the issue...it didnt.

So she decided to put it in a bowl of rice overnight. This had been a good fix on her old Iphone 3 when it got water in it.

I told her it wouldnt work but she did it anyway. Turned off the phone and popped it in an airtight container of rice. Got it out this morning and it works!

I have no idea whether this is due to the phone drying out or just being turned off to cool down over night but its working fine so far. I'll post again if the problem returns.

I put mine in a bowl of corn flakes but it didnt solve the problem

Well, having spent a week reading every nit of advice on every forum, trying them all and getting nowhere, I was getting desperate.   I live in West Wales in the UK, and the journey to the nearest Apple Store is eiter 2 hrs by train or a similar by road. 

My local Apple Reseller in nearest town could not help with iPhone issues and my phone services provider EE (Orange) could only suggest new phone. Free upgrade in 6mnths due but available now for £140 or so. Also outside of years warranty.

In desperationn showed it to guy with stall in the local market pavilion who does computer repairs and also handles Mac stuff.   He said straight away that it was a hardware problem and replacing the wifi chip would sort it. he could do it in a v short time!   Slightly apprehensively - but what the **** I'd tried everything else- I left the phone with him and told him to go ahead.   few hours later I called to check and he said "Yes, fixed."

And he's right. new wi-fi chip by anyone who can do it and thats the solution. Cost? £35.00

As a mega Mac family- Large desktop, Macbook Pro, 2 iPhones 2 iPads I think the Customer Service when Mac SURELY knew this was a hardware problem has been sub-optimal to say the least!   Will this post stay on this forum I wonder??

You've always upgraded to every new iOS at your own risk.  That's clearly explained in the Terms & Conditions you have to agree to before you can install the update.

Probably, but in an editted form.  You can't post people's private information on this forum.

So- theyve confirmed what I've just posted!  Hardware problem, get a new wi-fi chip as I did, problem solved!

You're welcome to have non-Apple authorized work done on your device. Just realize that such work immediately and irrevocably voids your warranty, and Apple is no longer responsible in any way, shape or form for your device.

If it solves your issue, then great.

@TJBUSMC1973 Of course it says that in the terms of conidtions. It has to. But this is different. They push out these updates, pop ups tell you to install it, you are reminded to do it when you sync with iTunes, etc, etc. When you buy an iPhone, you get access to future updates. This is like bringing your car in for regular service, the oil is changed, and then when you get the car, you can't go into reverse ever and the dealer says "sorry, can't fix it, you need to buy a new car."

If it is something that has to be done at your risk (and liability) then apple should not be pushing it upon you through the alerts, etc. That is a push process. It should be a pull process, the user should have to go find it and conciously choose it and there should be a pretty huge notice stating the risk.

That is not what apple did. I have full faith in apple that this was not intentional (that is that iOS7 would kill the wifi chip) but rather the side-effect or collateral damage of bad or no testing (it doesn't happen right away so could be missed).

Nonetheless, it kills a pretty big part of the functionality.

I have contacted the major newspaper tech columnists, Reuters news, bloggers and will contact the state of california consumer protection agency. this is pretty evil for apple. And let me add - I am a 2 iPad, 2 iPhone, 2 iPod Touch household, completely loyal to apple. Still pretty evil. Too large a financial impact for apple to cave. they have to be shamed.
