My Icon's wi-fi worked perfectly before the update, broke during the update, and has never been right since. I have tried soft resets, hard resets, and 2 complete reinstalls using the Software Recovery Tool. I have Bluetooth turned off. Sometimes my data won't connect either.
I followed the procedures on the link that PretACasser directed us to, and still no fix. I may have to send my device in because I really rely on the wi-fi. I love the phone and would just like to see it working properly again.
