    And when the WiFi previously grayed, works for a few minutes after 7.0.4 upgrade (and works fine!!!) and then it became grayed again? The WiFi is not burned...

     

    Just it is too much coincidence that hundred of 4S owners broke their iphone at the same time!


    What a pitty!

     

    If it was the software, then MILLIONS of iPhone 4S users would have the same problem.

     

    It's the hardware, not the software.  And wi-fi greyingout after an update has been happening for a long time, even before iOS 6.

    Tom, So what was it again that caused the hardware to fail? Thanks

    OK, so just got off the phone (52 minute call) from Apple support. They did 'diagnostics' whilst I was on the call and agreed that I'd done all necessary steps to fix the fault, but the 'Wi-Fi component' was broken and it wasn't a software problem and so couldn't be fixed in any way other than replacing the phone at a cost of £154 + p&p as it's out of warranty. I argued that there was no problem until the 7.0.4 update and they (advisor and senior advisor) said the update had "identified an existing Wi-Fi issue and notified me of the error". I did say it was a bit harsh that "notified" means "turned off" and I wanted to "turn it on" again, they said (as you would expect) you can't go back after an update. The only olive branch I have is that if Apple tech guys can identify that the fault was not caused by me (seems like an easy opt out) then the original supplier (my carrier) under consumer law in the UK should 'deal with the problem'.

     

    I did mention thatafter an internet search many others seem to have the problem. they said that Apple were "not aware of a problem". I did get the guy to agree that they "knew" about the problem but as yet had not "acknowledged" the problem, therefore in the eyes of Apple it doesn't exist.

     

    Bottom line is I'm screwed! No Wi-Fi, no mobile signal at my home so no phone. Thanks Apple.

    Same happens to me. I am very disappointed about Apple attitude on this problem.

     

    If it is a HW problem, is because they use a cheap or poor chip for WiFi. It can´t be a coincidence that hundred of people around the world has the same problem in such a short period of time.

     

    Perhaps iOS 7.0.X is so good, that it detected a bad WiFi hardware and it turned it off.... but, who should be blamed for this? Apple for installing this chip? or us for trusting Apple?

    7.0.4 didn't help me, so I went to the Genius Bar and my phone (iphone 5 on AT&T) apparently had zero wifi issues according to their diagnostic tools. I did have a number of crashes of some internal processes, however. The Apple Genius "refreshed my firmware", which apparently can be done with iTunes with a particular button holding sequence. He suggested that firmware can break just like hardware (ridiculous), and that it was possible the software that is responsible for controlling the wifi, battery, etc. could have a problem, and that the firmware refresh could fix it. I was highly skeptical of his explanation, but my wifi was working okay in the store afterwards. Of course, the problem returned soon after and my original symptoms returned.

     

    I went back to the Genius Bar again, and my phone still showed as "wifi working normally" when connecting directly to their diagnostic server. However, this time my phone would not connect to the Apple wifi network ("unable to join network"). The Genius I was working with this time decided to replace my phone, which fortunately still had 11 days on the original 1 year warranty. My new phone is working just fine.

     

    The fact that my wifi was still showing as working normally suggests that it was not a hardware issue, but that something was corrupted in a way that was not fixable during the ios 7 upgrade. It is possible, though, that my hardware broke in a way that was undetectable right around that same time, but I would think that would have showed up in the diagnostics check they run. My personal issue is fixed, although I feel bad for those of you still running into problems. If iphone wifi hardware breaks from time to time, statistically it will break for a small percentage of users at the exact time of an ios upgrade. However, the nature of the issues does not seem to be something common indicating a general problem, and I will still continue to blame the software.

    When the iPhone updates the software, the processor works harder than normal, and that process generates heat.  With a normal wi-fi chip, this amount of heat is within tolerances, and causes no issues.  With a defective wi-fi chip, this amount of heat can cause problems. 

     

    Imagine two bottles, both labeled as having a capacity of 1.00 liters.  One is defective, and actually can only hold 0.90 liters.  But that's not noticeable under normal operation, when you only use about 0.50 liters of water on a daily basis.

     

    One day, you fill both bottles with 0.95 liters of water; one is fine, no overflow.  The defective one spills over. 

     

    That's essentially what happens here.  The amount of heat generated in the update process is too much (or even the 'last straw that broke the camel's back) for the defective wi-fi chip.

     

    The chip was ALWAYS defective.  The defect only becomes apparent after the tolerance is exceeded.

     

    Does that make sense?  If it was the software that causes the problem, then all iPhone 4Ss would 'overflow'.

     

    And before anyone asks, if it was the processor generating more heat than it is supposed to, then there would be far more problems than just wi-fi.  The iPhone would probably not even power on if the processor was bad.

    He probably restored as new, during which the iOS software gets reinstalled on the device.  Your particular device may have had both a firmware issue (and yes, some things can cause firmware to get 'damaged', contrary to your belief), and an intermittent hardware issue.  Or the hardware issue alone could have been intermittent.

     

    I'm glad your device got replaced, however.

    I don't need the pretty little story, I just wanted you to admit "The chip was ALWAYS defective"....and who uses liters? When did you go all euro on us? It all depends on when the chip was made and where, etc. Not all are bad obviously, but they did make a bad batch of parts in which installing the software caused them to bite the dust. So under normal conditions (not upgrading the ios) our phones would be fine. Im not saying it is a software issue, im saying the software install causes the issue. The chip is already fried (thanks Apple) and even if it was possible to go back to ios6, my guess it the damage was already done and the wifi still wouldn't work. Still, not my problem...it's Apple's.

    Hi Lawrence, I finally had the time to run through all of your recommended steps, including restoring the phone "as new".  Nothing worked.  My wifi button still is able to toggle on and off, it is not greyed out, however the phone still does not find any wifi signals whatsoever. 

     

    Being out of warranty, I might as well get a new phone from AT&T for $200.  May not go with an apple phone this time around although that's what everyone in my family uses (facetime is nice).

    Here is South Korea. Same problems....here...

     

    Wifi worked well in 7.0.2.

     

    after 7.0.3 .....althought my iphone can find any AP. but can't connect some specific AP.

     

    and wifi speed is so....lower than 7.0.2....

     

    I'm crazy about these problems. I tried to fix my phone in every way.

     

    I had all set up and reinstalling 7.0.3....----> no Fix!!!!

     

    7.0.4 ......--> no Fix....

     

    my iphone's wifi component has problem?

     

    I really miss iOS 6. ---> really fast WIFI and 4G/LTE, really fast operation behavior.

     

    In same wifi environment, my iPad(1st generation) is WORKING WELL with NO PROBLEM to connect wifi. 

     

    What should I do next?

    I hear that now the 5s's are having battery problems after 7.0.4, just letting it sit overnight drains it. Nothing about wifi like on the 4s's.

    Hi folks,

     

    first of all: I own a brandnew Iphone 4s (two weeks old) in which ios 7.0.3 was already installed. I have no problems whatsoever concerning wifi or bluetooth. I also own a two year old Ipad 2 which I upgraded last week (via wifi), it's now running on ios 7.0.4, also with no probs at all.

    After having read a lot about the ios 7-problemtopics I do now indeed think that they are not due to the ios-updates, at least directly. Indirectly probably via defective wifi-chips (then the cause are the chips, the problem itself is triggered by the update, so to speak) just as TJBUSMC1973 wrote. Of course this won't help anybody who has connectionproblems, but to be fair this makes ist hard for Apple to find a solution. The only decent one in my opinion could only be that Apple replaces defective Devices also after warranty, maybe for a symbolic amount of money. Even if it's not the software the probs are still due to hardware failure.

    Sorry for grammarmistakes, English ain't my mothertongue :-)

    You hear all sorts of strange things on the Internet. I've had no such problem with my new 5S after updating to 7.0.4. Did you notice, for example, that after every iOS update over the past almost 7 years you "hear" about battery problems caused by the update?

    I had been getting very frustrated too with the wi-fi not working on my iphone 5. I installed 7.0.4 still not working, then reset network settings, rebooted phone etc etc, finally realized I had 2 routers, 1 relay and 1 main. Rebooted both of these (as suggested on this forum) and bingo!!

     

    hope this helps someone
