    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?
