It actually isn't the antenna it is the WiFi chip. Some people have had some luck putting it in a baggie and then into a freezer for about 10 minutes and then warming it with a hair dryer. Use Google for more details.
Others have had success with this: Call AppleCare and immediately ask to be transferred to Custome Service. Keep asking for a supervisor or manager until you reach a reasonable conclusion.
Thanks for the response. I agree, it is probably the wifi chip or controller, although no one knows for sure. It seems that the repairs on different forums are temporary. I have done plenty of research on this issue and I just want a permenent fix. I talked to a customer service rep, and then a manager. Nothing resulted except to send it in for $208 (with shipping) for a repair. They wouldn't even partially subsidize the repair, nor would they offer an upgraded phone for cheaper. The first rep saidI needed to go to an apple store which is about 6 hours away, and they could possibly do something. I think he just wanted me off the phone.
A question for whoever is reading this. If you have this problem, did you do your iOS 7 update over the air or through itunes? Mine were over the air, and I have a theory that could have caused it. Thanks!

They did offer to subsidize the repair. Your device is outside of warranty. Another iPhone 4S 8GB would cost you $450: http://store.apple.com/us/buy-iphone/iphone4s
They offered to replace it for $199.
$251 discount. That's 55.8% off. They ARE giving you a break.
Yes, really SMARTphone is useless without internet connection, and in my case, WI-FI because I can get it for FREE almost everywhere (home, school, trains ) where I live.
If my need is only to call, text, I would never buy iPhone or any other smartphone, and use simple mobile phone instead.
Another point is FREE, and when it is free you get unlimited freedom to talk (skypeapp), text (whatsapp). As a student who has limited income, I am limited to do it without free wi-fi.
I guess I forgot to add 'In my case,...' in my statement since easy access to information is very important to me. Many people buy smartphones because they like to play games on it, or just because it looks better than simple phone, so do not judge , many have differenet needs.
Have a sunny day !
My wifi stop working completely about a week ago, I have always updated my iPhone 4 over air.
Did anyone find solution?
ps. smartphone is useless without wifi, so annoying!!!
What troubelshooting steps have you taken so far?
Thanks for trying to help!
I have 'Wi-Fi settings grayed out problem' and did all instructions mentioned in http://support.apple.com/kb/ts1559 like Reset Network Settings, also restarting phone several times, taking micro sim out.
Hair dryer effect worked! But I still have a problem, it doesn't find my wi-fi network....
So I did the following:
1. Kept drying my iPhone 4 with a hair dryer for about 6-7min until I got 'Temperature' message.
2. Let it cool down.
3. After it cooled down, restarted it.
4. Wi-Fi function button on/off started to work!!!!
5. Around 15min after I turned on wi-fi button, it could find my wi-fi network, but quickly lost it.
6. I restart again, it could not find it.
7. I reset it, and also did Reset Network Settings again, but it still cannot find my wi-fi network.
Thank you for your useless comments TJBUSMC1973. How about a car analogy... would you like to pay 50% of the value of your car to fix (or replace) it following an ECU or TCU update simply because their update wasn't properly regression tested on legacy hardware. That makes sense! (sarcastic comment) Then, would you want to pay that much money to buy the same faulty car (refurbished) that already can't handle the newer update. Forget any future updates. That makes even more sense! (another sarcastic comment) You also aren't taking into account the lower present value of the phones in your calculations so they are flawed for that reason too.
Mkaie, thank you for having common sense and trying to help out. Good luck with your situation.
