My office has a password protected wifi. I’ve logged in many times, and I have enabled auto-reconnect. Many times, however, if I awaken my phone from sleep, I find I’m not connected to the wifi, and the reason shown is “Authentication error occurred.” I don’t know why the phone’s reacting that way. There’s no user or password change, and therefore shouldn’t be any authentication issue. If I ignore the situation, and check again later, often I’ll find I’m logged into wifi, despite having done nothing.
Is there some setting I should check to deal with this.
I have a Samsung S10+.
