I had a similar problem when I used my phone in an environment with very high humidity. Lost both wifi & bluetooth. Read a post about the hairdryer heating technique to dry out the wifi antenna. Didn't have a hair dryer, but had access to a free standing space heater. Put the turned on phone 6" from the heater ouput for 10 - 15 minutes or whatever it took to get the screen to say the temperature is too hot. Removed phone from heat source, shut off phone, allowed to cool to RT, then restarted. Wifi and bluetooth in settings were not grayed out and I was able to turn it on and get wifi and bluetooth connected. Apparently the moisture may have temporarily shorted out the wifi antenna.
Worth a try

Hi, we've had 4 Apple Iphone 4's now fail with regards the wi fi connectivity over the past month. We've tried a series of possible solutions however at the end of the day we paid for a replacement and now keep getting them swapped over. Apple infer they have an issue but continue to be uncooperative.
We're off to our local Apple store AGAIN today as our sons has has also failed.
Extremely poor service and feel we're treated like fools as they simply say they have no responsibility as we chose to action the update to7.0.4, not them!! (can ytou believe their arrogance)
Our daughter has moved to a Samsung Galaxy S4 and very happy. Given the past absence of service from Apple I suspect we will cut our loses today and bin the 4s and move to Samsung also.
Very disappointing especially on the eve of Christmas but Apple are so big that whilst they care so little and their service and quality is so poor they are however able to continue treating people as fools.

OK so my 4s has been working fine on IOS 7, then out of the blue lost my wifi.
Did all the usual resets, restores, DFU restore and still ended up with no wifi and rapid battery usage.
Freezer trick worked and got wifi back.
Used for a couple of days.
Took the back off and disconnected the battery.
Reconnected the battery and now no wifi!
Back in the freezer and Wifi back.
So whats with the disconnecting the battery knocking out the wifi - some sort of software reset?

yes that situation is almost the same for me , iOS7 was just fine , suddenly wifi was greyed out , but i didnt put it in the fridge , scared it will be damaged, but last week i did put it in the fridge , nothing happened .. the wifi was still greyed .. the problem with this greyed wifi , it makes my iphone so god **** slow, even the 3GS is faster than my 4S

Yeah its weird - did you put in the fridge or the freezer - Phone switched off then 30 mins in the freezer wrapped in a cloth and inside a plastic bag worked for me. I restarted while it was still quite cold, disabled anything that uses wifi in the background such as fetch and background app refresh and its been fine ever since...with brilliant battery life as well. I wonder if the problem isn't related to the wifi overheating - poor battery life due to the wifi running constantly might be an indicator.

Hi, believe the wifi grey out issue is pretty wide spread.
Whilst I tried a range of possible solutions at the end of the day nothing worked long term. I had one phone replaced no charge after much discussion with apple however the 1st which was only 1 year and 1 month old i paid for a replacement. Given I was unaware of the extent of the issue at that time I am now going through the civil claims tribunal to seek a refund. My view is if I created the issue e.g. dropped it, uploaded a virus, etc then it's my problem however given the issue is created by an apple upgrade they should fix it no charge.
Interestingly they told me its my problem as I not them chose to upload the update and sencondly the Apple store manager said as I bought the phone from Kogan.com.au that he would not asist me with regards a replacement.
Pretty poor form all round by apple but I gather their commercial success has made them bullet proof.

Yeah there does seem to be a massive problem. I still have the impression that the more you work the wifi the more likely it is to fail. Previous to mine failing, the iphone was always slightly warm to the touch, now with all background wifi usage turned off the phone is cold and has mega battery life. Not ideal admittedly...but at least its still working.

I have the same problem. I took it to the Apple store and was told there was nothing they could do other than sell me another phone. I declined. I looked into my credit card benefits and they have an extended warranty. I called the store to get something in writing so I could it in writing that it can be fixed and the woman who answered the phone said it can be fixed but she could not send me something saying what it would cost. I have to go back to the store. So after the holidays I will be going back to Apple to get something in writing. I have never had a phone malfunction after only a year, having to deal with poor customer service on top of that only makes it worse.
I have made my last apple purchase.

Hi. This happened to me and after a series of actions (crashing the phone, resets, turning off/on modem etc) I then crashed the phone with the 'airplane mode' on and when I turned it back on and turned that off hey presto it was working again and has been working fine ever since ... touch wood!! Hope someone else gets as lucky :-)
