Up until the latest Public Beta 3 release(Sept. 20), everything was working OK, not great but OK. Now, my Wifi cannot connect to the Internet. I know its my MacBook Pro because all other items in my house are using the wifi just fine. When I go to Network Preferences, I could through the Diagnostic process and the last three bullets(ISP, Internet and Server) are red at first, then after I click "Always Allow" they all turn green. I go to Safari, can visit 1 page and it happens all over again. Any ideas? Suggestions? It's very frustrating as you can imagine. I really regret signing up for this Beta version because it also does so weird double login when waking up and takes forever.
