Why does my phone forget Wi-Fi networks, how do I reconnect without reentering a password?

[Android Central Question]

I've input a password for certain WiFi network twice because after 7sing it the previous night,it asks me for password the next day without me necessarily forgetting it.

How often does this "forgetting" happen with this particular wifi network?
The owner can change the password.

 

[me just saying]

could be the saved password is wrong. try forgetting the network in settings, then enter the login info again.

Welcome to Android Central! Is this a private or public wi-fi network?
