Installed the update via the Software Updater this morning and after the prompted reboot I found I had lost Wifi access, as in no Wifi section available via Settings. This setup had been running just fine previous to the update. I have a TP-Link AC600 (rtl8812au) dongle.

I also have a Edimax USB WiFi adapter with a rtl8188cus chipset that I used in place of the TP-Link adapter while I dug out my ethernet cable.
Wireless Script Info I collected per the 'My wireless/WiFi connection does not work' post
I have tried uninstalling and reinstalling the driver for the rtl8812au chipset to no avail. I am not a power user so I am out of ideas as to how to diagnose and correct this problem
