I cannot connect my computer running Zorin OS to my BT Hub 3. I get a box saying "Authentication required by wireless network". When I enter the correct wireless key, the box simply comes up again. This computer has successfully connected via wi-fi to my BT Hub for several months without incident and I have made no changes to any settings on any of my devices. I can connect via BTWifi-with-FON, presumably to my own BT Hub.
