Can I just say that what kooa just said is exactly right and I agree with kooa 100% and I also saw that same YouTube video a number of weeks ago and have conducted the fix twice now( each fix was done right after doing a software update which then greyed out my wifi icon and caused no wifi) my wifi is still running strong after I completed the same fix as shown in the video (except I used my stove to heat the phone cos I don't own a hair dryer...lol)

I'm currently running on 7.0.6

I've been suffering from the wifi issues on my 4s. Apple told me it was not repairable. I tried the hairdryer trick (find on youtube) but it did not work. Found a company called fixmyiphone - they fixed it on the spot for £40. Highly recommend them. Posting this for anyone that has wifi issues and comes across this thread......

i heat up my iphone until it pop up temperature warning.. then i put it in the freezer...After that, when i turn on my iphone 4s , wifi already fixed! 🙂 and it is up till now

Hello there, I had the same problem with my iPhone 4S. The WiFi button is disabled, the bluetooth is scanning without giving you the option to toggle it on or off. And even,Settings > General > About > WiFi Address you will find that Your WiFi Address is (N/A)!

After replacing the Wifi chip 2 times (My warnaty is expired by now), it worked for days and it was back to disabled Wifi and Bluetooth. Settings > General > Reset > Reset Network Settings did NOT help.. neither restoring the device.

THE SOLUTION IS SIMPLY RIDICULOUS, I SWEAR THIS IS NOT A JOKE!!! YOUTUBE AND GOOGLE IT TO CHECK IT IS TRUE!

I used a hair dryer (as mentioned by several videos on YouTube) and simply raised the temperature of my iPhone until it said "iPhone needs to cool down before you can use it."

You will notice before this message showing up that your iPhone will start to dim the brightness to lower power consumption in order to cool down... DO NOT FREAK OUT!The message WILL BE displayed WAY before reaching a temperature that could ACTUALLYdamage your phone.. so CHILL OUT!

STEPS TO DO THIS FIX THAT HAS NO EXPLANATION

• Use a hair dryer to heat up the phone. (Place it on top of the phone, and make a gap between the phone and the hair dryer that is at MAXIMUM five centimeters)
• WHILE USING THE HAIR DRYER! Keep your phone from going to sleep. When you notice the screen is starting to dim.. flick through the home screen to keep it active and on.
• ** "iPhone needs to cool down before you can use it." WHAT NOW?! Turn off your iPhone and place it on a cool surface in room temperature (e.g. stone-surface Kitchen's counter)
• Leave your iPhone to cool down for 15 minutes.
• Turn on your iPhone... your Wifi should be back!

PLEASE UNDERSTAND!!

This method fixed 90% of iPhone 4S models that suffered from WiFi being disabled. The method does NOT have a clear answer to "Why does it fix this problem?"

Do NOT put your iPhone in front of the hair dryer and LEAVE IT!! Stay in front of it waiting for the message to be displayed! If you leave and forget about it, and the message is displayed and the hair dryer is STILL blowing hot air... it WILL damage the device!

I HOPE THIS HELPS 🙂

The most reliable way to fix all your problems with your iPhone 4S is simple.......and I'm gonna call it the HIFFIE fix

Heat It

Freeze

Fixed

Enjoy Everything

Just do it!

Updated iPhone 4s to iOS 7, WIFI gone!, Bluetooth gone!...and now so has my iPhone...into the bin and replaced with a beautiful HTC 1 which works! Apple have lost another once loyal customer. Shame on you, Apple.😠

OMG - I can not believe that heating my phone to the point of a thermal meltdown would fix anything. You'd expect the exact opposite. However, after seeing all the "melt your phone to fix it" posts I said what the **** and tried it. Son-of-a-ditch if it didn't work. My favorite all time IT laugh used to be "no keyboard present, press any key to continue". Gonna have to change that to "iPhone problem, pre-heat oven to..."

Thanks. You da man zane ... crazy that this works, but it saved me from bringing my son's iPhone 4S into the 'shop'. Also crazy to think that Apple knows about this software glitch and hasn't done anything about it. Next challenge is figuring out to get out of a group chat in iMessage. Ah Apple ... thank you for reminding me why I remain a satisfied android customer.

Here's another thread and welcome to the club.

Well, good luck to you all, and Adios, Apple! I have just purchased a Samsung Galaxy S4 and expect to have a much better experience. I also ditched AT&T for Credo Mobile so some of my money goes to causes I support. Best of luck out there to all you disgruntled iPhone users. Apple, you have lost a loyal customer due to your lousy customer service. I will look for alternatives to Apple for any electronics products i purchase in the future.

Thank you everybody for visiting my thread. I am unsubscribing to it now that I have found my better option.

I discovered that when I deactivate cellular data and 3G in Settings and cellular, I don't have the wifi problem anymore. It's as if this way it generates less heat and the wifi chip or ios 7 can handle it this way.

It happened to me too. I challenged the "geniuses" at apple and apparently it would cost you 200$ to get your ios7 installed on your 4S - that because you have to repair /change it after the install. I guess they want to make their research on their products reliability on the customer's money.

If it would have lasted for 3 yrs I would have said ok this is what one usually expects from a phone but for them to fail right after iOS 7 install ... is pure BS. It looks like Apple is not anymore what it used to be. Me for one I won't buy ever another iPhone.
