iPad repeatedly asks for WiFi password although unchanged
To those who experience Apple products 'forgetting' (temporarily or indefinitely) a WIFI password, this is AN APPLE FAILURE - not yours.

Equally failing are the responses you'll get to 'reset network settings' that will delete ALL of your saved WIFI passwords. This is a totally unacceptable response and should be avoided. Same goes for completely restoring an Apple device to resolve some mundane issue that renders your Apple product less than useful and lacks a true 'fix' from Apple.

No other product line outside Apple has this chronic problem that has made it through every generation of OS and iOS.

Since the issue has never been resolved for the end user, one can only surmise Apple has good reason to inconvenience users with this.

Not amused.

Solution: other than resetting network settings and losing all logins... one can (usually) find success by turning off WIFI and waiting some time before allowing your device to re-login. Or, one can reset (turn off and on again) all devices (including modem/router/etc) EXCEPT network settings on the Apple device and that should clear the problem. It is an inconvenience, but it should work.

And for the few that will be forced to reset network settings, and lose everything, I'm surprised you haven't sued Apple for the loss of business - if taking a chance using an Apple product for your business.
