Sometimes our Internet service (terrestrial wireless funneled through our router to all devices in our house) temporarily stops working, but comes back up within minutes. During and after the outage our Windows and Android devices never report a problem with the WiFi password, just network issues, and never require the password to be re-entered to re-establish connectivity.
On the other hand, our iPad Air 2 (Version 11.2.6 (15D100) Model MH182LL/A) frequently requires the user to re-enter the WiFi password, on some occasions many times. This despite the fact that the Internet interruption has nothing to do with the WiFi password. Once I "Reset Network Settings" on the iPad, and naturally I expected to have to enter the WiFi password once more, but as before I must enter it again and again.
The router is an ASUS RT-N66R and I have changed little of its defaults other than of course the password, but I changed the password shortly after buying the router and haven't changed it since.
How can we avoid having to re-enter the WiFi password on the iPad every time there is some kind of Internet interruption?

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.
