HI, I have come across the wifi issue - where the Wifi icon is grey out. It started with Wifi icon grey out, and restarting the device sometime works. But it is completely dead - Bluetooth button is no greyed out but even its on theres no connectivity. The device also not able to accurately detect my location. After much research, I narrowed down to the possible fix of replacing the antenna flex cable. Took me about an hour and some sweat to get it down last night, restarted the device, issue still exist. Question: should I both with trying to replace the wifi antenna piece? or it is pretty much done deal - get over it Brought it to Apple they did the diagnose, as expected, they confirmed the wifi failed - asked ~$400 to get a replacement iphone 6. Just want to get you guys thought on next possible fix, if there is any

Which in that case you’ll want to send it off to a reputable board level repair shop Reset iPhone Network Settings. Settings — General — Reset — Reset all Network Settings.
