4s does not connect to any wifi at all
My 4s just been used for one year, never been dropped. One day, it just stopped to connect to any wifi. Under the setting wifi, it is completely greyed off. Apple tech said the chip to connect the wifi is broken. This phone cannot connect to any wifi now. I have tried switch off and on and still not help. Any expert has idea how to fix that? I am so disappointed with this Apple now!!!
Это хороший вопрос?

bad apple, I guess the very first step would be to disassemble the phone to see if there is any obvious damage to the WiFi circuit. Sorry about your bad experience. With a greyed out WiFi it is usually that the firmware does not find a Wifi IC
