iPhone 4S cannot scan for wireless network since yesterday and i was using WiFi perfectly

So yesterday i was using iphone browsing internet, playing games, etc. And in the evening i unlock the iphone and didn't see the wifi status on the status bar. I click setting menu and it took around 30 seconds to open it, and i click wifi, the little ball keeps spinning but none of networks show up, i try to join the net work nanually, but when i click join, it says "Could not scan for wireless networks". At first i thought this is a hardware problem but when i look up my question on the internet a LOT of people appears have the same problem, and some of them said they did not had any wifi scan problems in ios 4 but after they upgrade to ios5 they had this problem.

My iPhone 4S is broght in April 2012, comes with ios5.1

Thanks A Billion!!! please save me~😐

iPhone 4S, iOS 5.1.1

So i called apple support for help on my iphone... After downloading iOS, my phone wont scan for any wifi. i tried it everywhere my house, friends, restaraunts.

Dont bother calling them, They tell you to restore your phone to factory setting, give you case number, get your phone number incase you get cut off, transfer you their manager in the end wifi still not working and you need to pay $199 for it to be fix.

I think its BS that i need to pay for it after all its their sofware (iOS) that mest up my WIFI. so ill just wait for my contract to be done and im switching.

So please dont even bother calling them for help in the end they will charge you $199 for your phone to get fix...

Their excuse that my warranty has expired and cant do nothing about it.

DO NOT DOWNLOAD iOS ITS MESSES UP YOUR WIFI!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

@iphonesuckass

Dude you gotta chill, your 1 year complementary warranty expired. And if you think you are covered by warranty, bring that to apple care and ask them to replace it. We are just users and cannot give you any guaranteed solutions. iOS is fine for me, no problems at all. It is not a excuse that they are not going to cover an OUT OF WARRANTY device, and if you arent ok with it, go away. Apple clearly stated that the complementary support is one year if no additional apple care service purachased.

UNBELIEVABE!!! I hope you get this message because I have spoken with Apple support, did the erase, reset, restore with no success. Then I went into the Apple store & was convinced by Apple techs my wifi no longer worked because of the message "cannot scan for wireless network". This occurred after the latest update & my phone had been working great. Tonight I googled "cannot scan for wireless network" , went through the comments, found yours, followed the steps & YAHOO for YOU!!! I don't have to go buy a new phone.... THANK YOU!!

What solution are you referring to Cazadora30?

My iPhone 4S (locked with a carrier from Romania: Orange) is not able to scan for Wi-Fi networks. I was thinking maybe the Wi-Fi chip or antenna are broken BUT surprise today when I tried to introduce a new SIM (from a different carrier) restarted by itself and then in the process of activation was able to see the Wi-Fi networks and I connected it to my home Wi-Fi and it worked just fine for about 30 minutes when I tried to turn off the Wi-Fi and turn it back on again after 15 seconds, this time was not able anymore to scan for Wi-Fi networks. This lead me to the conclusion that the Wi-Fi chip and antenna are ok but may be a software bug. These problems started when I had IOS 8.1.2. I have upgraded to IOS 8.1.3 which is the current version and it still won't work. Furthermore I have deleted all the data on it and reinstalled the IOS 8.1.3 setting it as a new device but still the problem persist: can not scan for Wi-Fi.

Does anyone have a solution for this problem?

Fantastic! Daryl's instructions worked for me. And I was worried because the warranty expired long ago.
