My Iphone 4 32gb black can't find any wifi network

my iphone 4s have this question too,It can't find any wifi.

I follow all of this but it didn't help; I even restored it. My iphone 4s wifi could not scan any availalbe network (my university and home wifi ...) about two days ago. When I turn it on, it acted as it 'Choose a Network' but never found any. I want to ask you is it a software or hardware problem? Thank

My iphone 4s has this problem too, it acted as it 'Choose a Network' but never found any, Is your problem solved, how can I do now?

If you have done everything already but your wifi still doesn't work. The best way is to report this problem to Apple and get your case number. Then call them, tell them your case number, you follow what they ask for: Serial number, last 4 digit of IMEI, .... Finally they will give you an Apple repair number, go to UPS store that they tell you to go to, tell UPS your repair number then UPS will send your phone to Apple for inspection, and repairing. Hope this would help you :-)

PS. I know the feeling when our Apple devices have problem! We simply get mad 😢

I just did this and it worked great:

Reload your network as an OTHER network. It will have you ask for the network name and WIFI password again. From here you should be able to bounce right back.

My GUESS is that the original settings of your previouly loaded WIFI network settings were somehow changed, either on their own or on accident. Either way, doing this worked for me about 10 minutes ago. Ill let you know if it dumps again.

Hi guys, I've got very special Russian lifehack for this case: just put your phone in the fridge for 10 minutes. IT WORKS!!! I'm not joking. 10 minutes ago i had my phone with absolutely grey out wifi, but now, OMG, it just ******* works!!!

**** I have got same problem now!!!! it was working proberly at first didnt noticed it before i've bought apple tv.. needed to connect to wifi when i notice it greyed out an not funktionel... super!! anyone wanna buy a apple tv devise?????

you right cyborg it worked for me 🙂 thx for the tip!!

The sad thing about it is that you have to repeat from time to time... so, it was my third frige time from my last post today 😉

not able to connect wifi. I have iphone 4s. it worked until yesterday.

i tried resetting but not working.

any help

this is brilliant. My mom's phone couldn't find any networks, so I tried it, because why the heck not, and when I went to the WiFi settings, it found the network. It had a little trouble conneting, but. This is legit. Nice hack, thanks 🙂

The freezer really works people!!

My 4S couldnt detect any networks today.

With little time i found the freezer idea on the forums, i thought it was BS to be honest.

But i tried the whole airplane mode and network reset and nothing worked so i tried the freezer.

Ziploc bag and left it in the freezer for 30 mins with 20% battery life. When I pulled it out it was dead so hooked it up to the charger, waited for the chagre and no success on the wifi. So yah i thought BS.

So then I followed all the other apple care steps such as backing up the phone, erasing the phone. But even when the phone was erased it couldnt detect any networks. So i restored the phone from itunes and still no wifi.

Then I read a key note on the forums about the freezing.

They said turn the wifi off and cool for 10-15 mins

So iphone being charged now after the back up and restore i tried the freezer again.

15 mins in ziploc bag with wifi off and full battery and behold!

I finally detected networks again!!

Good Luck!
