I cannot ON my WiFi after I had update my software to iOS 7.1.1 on my iPhone 4s

My iPhone 4 s is funtioning properly for more than one year. Recently, I had Update my software to iOS 7.1.1and now I cannot ON my WiFi. The ON button on the WiFi is in active. I have friends who are also facing the same problem.

Troubleshooting 1:
Turn off the airplane mode by tapping Settings > Airplane Mode, then do the network resetting by tapping Setting > General > Reset > Reset Network Settings, and finally restart the iPhone 4S.
Note: If you reset the network setting, all recorded data will be removed, such as the Bluetooth pairing records, Wi-Fi passwords, VPN as well as the APN settings.
Troubleshooting 2:
You also can try this Wifi solution for iPhone 4S: Setting > General > Reset > Reset All Settings.
Note: This troubleshooting may fix the Wifi problem, but it will remove all of your preferences.
Troubleshooting 3:
If you have tried the above solutions, but still face the iPhone 4S Wifi issue, you can check if your 4S is upgraded to the newest available software. You can restore the iPhone 4S after checking the software updates in Apple iTunes.
Note: Restoring the iPhone 4S as a new phone is a slow process and it will reset your 4S to the factory setting. But you need to reload all your contacts or media information to the iPhone 4S after connecting your device to the computer.
Troubleshooting 4:
Some forums threads suggest another solution to fix the “gray out” iPhone 4S Wifi issue: placing the iPhone 4S in a refrigerator or freezer for several minutes, for they considered the 4S WiFi issue after iOS 7 update is caused by the heating issues.
Note: The lower temperature in the refrigerator or freezer may cool down the heating WiFi radio chip and will temporarily solve the WiFi problem for iPhone 4S, but the warm and cool temperature shift between the refrigerator or freezer and the room may cause the potential damage to your iPhone 4S.
