my wifi won't turn on on my iphone 4s, how do I fix it?

I Have a perminant fix for this wifi not turning on 🙂

1, get a hammer, bigger the better, place fone on a concrete floor and smash it

2, buy another fone but make sure its not apple, this will happen again when apple want you to upgrade and buy a new phone, there is actually nothing wrong with the device, it is all to do with your last ios update, they install a script that after 3 months things stop working, they wont never have a fix so dont waste your time, and if you decide to buy another iphone and support these people that broke your phone, then your supid.

When I go to settings to turn on my WiFi, it says WiFi off and the sliding part remains gray and will not slide. I know the WiFi in my home works, because I am the only one who can not use it. I did not drop my phone or damage it, I'm not sure why it is not working. I've already gone to settings>general>reset and reset all settings and reset network settings several times, and I've also reset my whole iPhone to new from iTunes and that didn't work either. How do I fix this? Please

I tried the reset of network settings multiple times and it didn't work for me. So, there was a video posted on the heating suggestion. I got the hair dryer and heated the phone all over for about 5min. I didn't get the overheat warning message but the phone was quite hot to the touch. So, I did the turn off using the power and home button together then placed it in the freezer for about 10min wrapped in baking paper. Sure enough when I turned it back on the wifi was now working. I will wait and see if the problem appears again and post again if it does.

I have the same problem and really disappoint me!!,

I recently switched from my 3GS to an iphone 4s and I have the same problem. Everything else works fine but the Wifi setting remains off and gray as you said, but will not slide.

Does anyone at apple have a solution or do we need to return the phone?

Wyattmp3 what did you do?

sounds like you were pretty thorough there. sadly, your phone might need service. here are the steps Apple has: http://support.apple.com/kb/TS1559

I have same problem please help me guys thanks

I just started having the same problem 2 days ago. My tone's bluetooth won't stay connected, either. I have reset the network settings twice and restarted phone. nothing works!!

I also had the problem out of the blue. i read the previous comments and contacted Apple support. They ran through a diagnostic process and determined the wifi module was bad. I still have a warranty on the phone and they made an appointment for me at a local apple store the same day.

i just bought this iphone today from someone, i have 200 mb of data but apperently it takes that much to donwload a couple apps.. but anyways my wifi isnt working and im having the exact problem..it most likey wont have a warrinty on it so like what do i do

i habe same problem if u get any solution 4 it then please let me know bro

If you still haven't fixed it and the apple trouble shooting does not help, than try this. First put your iPhone on airplane mode and then shut it off. Wait about 5-10 minutes and then turn it back on and check to see if the wifi button will work. If it still does not work, make sure that your ios is completely updated. In order to update, you have to be connected to a home wifi signal so if you need to update, plug your phone into your computer and open iTunes. You should see a window pop up right away that says that your phone needs an update. Once your phone is done updating, retry the steps in the beginning. worked for my iphone 4s

I just discovered after upgrading to 8.0.2, my 4s stopped recognizing my wifi. I followed a recommendation to reset the network settings, now the **** thing will not allow me to switch on the wifi button in settings. Do the idiots at Apple read these posts - they had a good product they they screw things with untested upgrades?

This did not work for me.

This fault cannot be fixed. I took my phone to the Genius Bar at the Apple store. Reinstalling the software did not help and they told me that I would either have to do without wi-fi or get a new phone.
