Does anyone else find that when connected to WiFi after any amount of time, short or long it acts as though you are not connected. When you click the WiFi button it shows as connected, but with the message "Couldn't authenticate connection". It doesn't appear to be my WiFi as other devices and users are accessing and using it without disruptions. I eventually get reconnected after turning the WiFi off and one a few times, but it would be good if anyone has a fix they can share. (I've tried a restart and OS update and it's still the same.)

Thanks
