My Iphone 6s wont connect to any wifi..it keeps saying wrong password...i have tried all the suggestions online but they dont work.
If you already tried (to no avail) all the steps provided in the support article I posted AND if you already tried to restart your modem-router, then yes, it could be a hardware failure on your device.
Have it inspected at an Apple Store or AASP.
