10.10.2 broke wifi in OS X (but not win8 in Parallels)
After upgrading from 10.10.1 to 10.10.2, my MacBook Pro connects to my Apple Extreme via Wifi, but not to the Internet. (On a side note, the Extreme also reports not having an Internet connection.)
However, other devices connected to the Extreme via Wifi, do access the Internet (they run Android, iOS and Windows 8). And on the same Mac that can't reach the Internet, I'm running Parallels Desktop with Windows 8 installed, and here I'm getting a good Internet connection (Parallels is running its network adapter in bridged mode, meaning it's visible to the Extreme as a separate machine).
So, despite the Extreme's odd status, the Internet is available to all my devices, but not Mac OS X. Also, the Mac's wifi hardware must be working, since it's good enough for Parallels on the very same machine.
What is it, then, that's causing OS X to not connect to the Internet?
MacBook Pro (15-inch Late 2011), OS X Yosemite (10.10.2)
