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~😐

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?

Apple normally doesn't fix, they replace, if covered by warranty.

I took my phone in to Verizon this afternoon with the same issue and they overnighted me one for free. Not really a solution but I'll glady take it as I have accumulated a few scratches.
