As you may know, I’m just back from Beijing. During my trip, I used to switch on airplane mode to avoid any roaming charge. But sometimes, when I was in a cafe with free Wifi, I turned the Wifi on again. Everything works really fine until I was back home. When I tried to connect my iPhone to my home wireless network, it didn’t work. As I checked out the Wifi option in “Settings” screen, the Wifi option is just grayed out or disable by iPhone itself. Even I rebooted the iPhone, the wifi option still stayed in disable state.
This is not the first time I heard from my readers or other jailbreak iPhone users about this Wifi problem. But this is the very first time I experienced it on my iPhone.
And here is the fix:
Reset the Network Setting
Yes, by just resetting iPhone’s network setting, the Wifi option comes back to normal. To reset the network settings, go to “Settings” -> General -> Reset -> Reset Network Settings.
I’m not quite sure if this is the universal solution to the Wifi Grayed-out issue. But this one works for my case. Leave me comment and let me know this works for you or not.
