Earlier this month we brought up a widespread issue regarding iPhone 4S users who updated to iOS 7, only to experience Wi-Fi being disabled (i.e. greyed out and inaccessible). The story was shared with us by frustrated iPhoneinCanada reader Trent, as his wife’s iPhone 4S no longer had Wi-Fi access.

WARNING: try this fix at your own risk. We are not responsible in any way if this method causes permanent damage to your iOS device. 

Now he has shared a popular working solution which has solved the iOS 7 Wi-Fi woes on his wife’s iPhone 4S. It involves using a hair dryer and heating up your iPhone 4S until you get a temperature warning pop up saying “iPhone needs to cool down before your can use it.”

Once this message appears, pop your iPhone into the fridge for 10 minutes to allow it to cool down. Once that’s done—Wi-Fi should work again. This worked for Trent’s wife’s iPhone 4S and also many others who have been stuck with this problem.

The video below explains the fix to the greyed out Wi-Fi problem on the iPhone 4S in more detail:

If your iPhone 4S has its Wi-Fi greyed out in iOS 7 (some users have had this issue prior to iOS 7 as well), let us know if this overheating trick works for you.
