Forum thread on OSX Yosemite Wifi issues now 64 pages. (Includes tips that may help some users but not all. Also saw a post that OS X 10.10.1 beta helped.)
Reminder on Screen Sharing and iTunes HD video playback problems (HDCP):
If you're suddenly unable to play protected iTunes HD content after an upgrade ("This movie can be played only on displays that support HDCP..."), check System Prefs/Sharing to see if Screen Sharing is enabled - if so disable it. (This has been mentioned before but repeating again after a report of Screen Sharing enabled after upgrading to Yosemite. There are other causes of course but screen sharing was the first item to check in previous post on Tips for HDCP Errors/Problems playing purchased iTunes HD Video.)
