I upgraded to Ubuntu 18.04 and now cannot connect to wifi. If trying from system menu, I see "Connection failed - Activation of network connection failed". Wired connection is working. Network adapter is Qualcomm Atheros AR9485 but driver is missing in "Software and Updates - Additional Drivers". Here is the wireless info:
