Wi-Fi Bug/Failure 10.10.5 Yosemite (after update)

Since 10.10.5 my Mac Pro WiFi connection will work only for about an hour give or take.

Only solution so far is to save everything and restart.

Symptoms:

WiFi Signal in Menu Bar Shows full bars

When I select the Menu Bar WiFi item, there are no networks in the list anymore, and it asks to Turn Wi-fi On.

Selecting to Turn Wi-Fi On does nothing, Wi-Fi remains Off even though it is showing full bars in menu.

Going to System Preferences, the same issue.

Impossible to Turn Wi-Fi On, even when going through Diagnostics.

Possibly a Harware Issue?

Mac Pro, OS X Yosemite (10.10.2), Early 2013 4 Core

What does Wireless Diagnostics show?

Also try turning off Bluetooth.

If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.

Wireless Diagnostics does not show any errors when it is up and working.

Wireless Diagnostics will not even finish when it is not working simply because the WiFi will not Turn-On.

It loops endlessly trying to turn on Wi-Fi.
