    Hi there,

     

    I would recommend taking a look at the troubleshooting steps found in the article below.

    I got the same problem. i even restored my 4s and still my phone cannot detect any wifi connections. PLEASE DO SOMETHING ON THIS APPLE! is it because of the new iOS7.0.3?? now im ******.

    Same here ! everything was working okay before 7.0.3 ! now wifi disconnects and i cant see any more wifi signals and when i try to acess wifi network the screen freezes !!

    Same here, 4s working perfectly, downloaded update 7.0.3 Now no wifi or bluetooth or hotspot. Control on/off icons are muted in colour and don't respond. Tried resetting network connections then total restore, didn't work so still have the same problems as before.

    This may be a hardware malfunction, try the troubleshooting steps listed in the articles above and when it´s not help, claim your warranty and get a repair or a replacement.

     

    It could be this esay. I did not think thats a problem with the iOS, i think theres maybe an issue about this WiFi module build in the 4s

    Guys I had this problem a whiles go but I solved it by placing my iPhone in the freezer for around 10-15 mins! Make sure the WIFI is turned off while it is in there, take it out and turn the WIFI back on, it should detect the networks.

     

    The iPhone might restart after taking it out, that's okay just make sure it's in a dry place in the freezer. I know it may sound crazy, that's exactly what I thought but it worked :P

     

    Try at your own risk though, it worked for me but might not for you :)

    FOR ALL THAT IS GOOD DO NOT DO THIS!!!!!!!!!!!! ^^^^^^^^^^^^^

     

    1. Turn off iPhone

    2. Restart router

    3. Settings>WIFI>other

    4 enter Wifi name and security type, if you dont know the security try one by one

    5. Enjoy Wifi

    Hey buddy,

     

    I had the same issue, but found that by removing the space that i had in the wording of my "router name" fixed the problem...

     

    For example:

    Originally

    Nevs Wifi

     

    Current

    NevsWifi

     

    Hope it solves the issue

    Try  a hard reboot holding the power button for 30 seconds

    Look I realize we all think that the idea of putting the iPhone in the freezer is absolutely crazy, but absolutely NONE of the other steps worked to get my iPhone to recognize any WIFI networks. 

     

    I think if you look up the specs on iPhone 4S  you'll find:

    Operating temperature: 32° to 95° F (0° to 35° C)

    Nonoperating temperature: −4° to 113° F (−20° to 45° C)

     

    6 minutes in your freezer is at best likely to get the thing to 32°F or a little less. I think a really good freezer can get down to about 5°-10°F , but  -4°F not likely.  So if the phone is off (and I suspect in Yousif's recommendation it doesn't matter if it's on or off so I'd try off first) you should be pretty safe.  I actually kept mine on and put it in sleep mode, but for those of you less brave you can just turn the darn thing off.  I doubt it matters.

     

    Now oddly enough this actually worked!!!!!

     

    The question is why?  I'm guessing that in some cases there may in fact be a hardware issue in which the cold temperature causes the machine to reset mechanically/electronically but not from a software perspective (which is why the network reset may not have worked).  Components that may have over heated when cooled down contract a little and conduction between electronic parts perhaps improves.   Once re-established will it continue working?  Who knows?  Be nice to get an actual APPLE perspective on this. 

     

    I think we all know that when our phone overheats that cooling it down can get it to work again.  This is pretty well documented and I'll bet that some of us even stuck the darn thing in the freezer or put it on ice because it was taking so loooooooong to cool off.  Is it really so far fetched to believe that there is a lesser level of overheating that doesn't shut the phone down, but will shut the WIFI down until it's reset with a cool blast.  Perhaps even just being turned off  WITHOUT being in the charger will do the trick, but it may take a lot looooooooonger (my guess a few hours or more can you live without your phone for that long?).    If so, perhaps you might have someone open the phone and clean it out to make sure there isn't some lint or dust causing it to heat up a little more than it might otherwise do.

     

    Just a thought.  Yousif it would be nice if you shared where you got this idea? or reported whether the problem ever recurred after your last deep freeze.

     

    Thanks a million for it!

    Freezer for 10 minutes worked for me!!!!!

     

    I turned off wifi and bluetooth left it in the freezer for 10 minutes.


    When i took it out the battery was temporarily dead, plugged it in. After 5 minutes it turned back on.

     

    I clicked on the wifi and to my amazement after 1 year of no wifi IT WORKED!!

     

    THANK YOUUU

    Hey there,

    I'm really glad it worked for you! I got the idea due to the fact that my iPhone had heated up before I got the wifi problem and so I thought that some of the components would have over heated or something similar and so I tried it and it worked.

    I have sold my iPhone now and gotten a 5S and so far all good :)
