My internet connection suddenly stopped working 1 hour ago. It asks me to enter the "network security key". And when I enter it, I get the message: "some information changed since the last time you connected".
I did not make any changes to th network security key for many years. Why am I having this issue?
You may want to tell your device to forget the network and try to connect to the wifi again. Or you may want to try the default wifi password which is typically on the bottom of the router on a sticker.
