After update my iphone 4s to ios 8.3, it can't join any wifi
I have just update my iphone 4s to ios 8.3 (in 06/05/2015). I am disappointed because after updated, it can't joint any wifi (free or not free) that it can join before.
How can I do now? Can I return it to ios 8.2? pls help me.
Thank you very much.
