wifi greyed out after update to ios7

Here we go a new thread on IOS 7.1 killing WiFi.

https://discussions.apple.com/thread/5981770

What do you guys suggest about updating my wife's 4S to 7.1. Should I take to Apple store and have them do it? I am not ready to shell out another $200 if it fails again.

How can I know if the phone has the bad batch of WiFi chip from crapola BRCM.

Wifi greyed out again last night so I repeated the advice given previously re heating for 170 for 3 mins under halogen lamp. Hey Ho the WiF returned after cooling down for 3 hours

I have the exact same problem! I am very frustrated by this and apple. I have a 4S and I lost wifi after updating software. I attemped resetting network settings, updating, rebooting, etc. I even replaced the Wifi Antennae to no avail.

I understand its likely a problem with the WIFI chip- which cannot be repaired since it is soldered onto the logic board.

Apple said I could have the phone repaired for $200, which is how much I paid for the phone a year and a half ago.

This is my 5th iphone, and I have always been a huge fan. I am so very dissappointed right now that I am considering other phone-maker options. This is unacceptable.

Apple has always been a company with integrity, I hope they make this right for their users.

I have read through all that you have said and I do believe the software CAN affect the hardware. You must know this too? If the code/driver is badly written and there are some potential handsets out there (like mine) that have heated up and failed it's because the code wasnt written to cover the highest risk factor and the hardware is being worked to much and thus overheating. This happens with MAC and PC software/hardware all the time, it's fact.

My iPhone 4S has failed since yesterdays upgrade iOS v7, it was fine before. I looked at the logs and there it mentions loads of panic error codes, which explains all of the above!

The code behind it is the problem, it was written and tested and as long as the failure rate was under a ceratin % then it's released into production, but that small % in real terms (amount of handsets is probably a huge number).

If the code/driver was 'badly written', then all iPhone 4S units would have the same problem. The code for every single iOS 7.1 install (barring the random and rare 'bad install') is identical on every single iPhone 4S unit.

If the code is identical, and not all iPhone 4S units are affected, then what does that tell you?

If you meant that the code wasn't written to take into account defective or out of tolerance hardware, then that's a backwards (and very convuluted) way of saying it's the software's fault.

But that's like saying that a restaurant is 'defective' because it serves tomatoes, and a guest who is allergic to tomatoes eats one and gets sick. There's nothing wrong with the tomato. It's the guest that has the 'defect'; i.e., the allergy.

"If the code is identical, and not all iPhone 4S units are affected, then what does that tell you?"

It tells me that Apple got some shoddy (cheap) hardware and no problem using it in their very expensive devices. The software behind that isnt communicating with the hardware on all levels, thus going into panic mode, which will cause any piece of hardware to malfunction (in this case overheat) as it cannot compute the code.

I never said it would affect ALL 4S units, but the QA/testing of the software didnt cover all the potential hardware out there, and I bet you it's because Apple do not even know what WiFi chips they have in a percentage of their (expensive) units!! Thats TERRIBLE business and only profit making.

If you release a software update you must check it would workwith all the known hardware, which they probably did, but it could say that they dont have a clue whats in their devices and then expect the end users to pay money for their bad due diligence.

Do not forget, my unit failed instantly after the new iOS 7 update yesterday, it's 2 years old without ever having a problem. Surely you can see some not right about that?

If a car, fridge, TV, etc etc... manufacturer finds a defect they recall and rerplace for free, and because Apple are not doing this I am going to go elsewhere, probably Nokia. They make the best smartphone now.

IOS7 downloaded to my iPhone4 without my knowledge or approval. When I tried to remove it to regain space, I screwed up and was forced to install ios7, which resulted in a battery hogging, hot, slow and unresponsive iPhone4. I finally restored as a new phone which solved the battery and heat problem, but the phone was a LOT nicer with ios6, I've noticed that the camera is not as good, and the text looked like a printer running out of ink. Apple should at least allow us iPhone owners to use whtever ios we want because to aggravate thier loyal customers too much will eventually impact their profit. My wifi has worked ok so far, but I no longer use it due to Apple's forced downloads via wifi. I no longer upgrade anything Apple until I can take a look at these forums and decide if the upside is greater than the downside. Too bad Apple combines security updates with their upgrades though.

You have a defective unit. The fact simply is that the defect didn't reveal itself until now.

What is the percentage of iPhones that have defects?

What is the industry average for all smartphones that are defective?

No, it did not. You actually have to tap on 'Software Update' in order for it to download to your device.

Perhaps, but I never intended to download ios7, maybe I pushed the button when the phone was in my pocket, because I would never have done it on purpose knowing what it would do to my phone.

I recommend using the lock screen function when you're not going to be actively using your iPhone.

I thought I was!

Set your phone to have autolock after 1 minute if it is unused, that way if you forget, it locks itself for you.

Thanks, will do.

It is a hardware issue. all the presumtions, that there is a software related problem, are false. I tried all of the suggestions, updates and it did not get the wifi slider to move. WLAN just died upon update. sent it to PODMOD . de and the germans fixed it in two days. they speak english. paid 29 euro for the fix plus postage. told me there were two options:

1) the fix, possible if the WLAN CHIP is not damaged or

2) the exchange of the Chip, which costs 69 euro.

was lucky to get it fixed for 29 euro. That was at upgrade from 6.x to 7.x. My sister had issues with update to 7.1, i did not. again, sent it to podmod . de and got it fixed in just two days with postage. paid with paypal. reading this thread makes me wonder what magic tricks folks believe and what they do in plain belief that some magical twists would get a hardware fail heal. it is hardware and it needs a fix.
