Ever since upgrading to Mountain Lion, I'm having an issue where after the computer wakes from sleep, I get constant beachballing, but ONLY if the wifi is enabled. If I disable wifi, the computer will perform flawlessly. For the sake of completeness, I also have a wired ethernet connection plugged into the computer at the same time that my airport is enabled. This has never (and should never) create an issue. Network priority is given to the ethernet.

 

You can see a video of what it does here:  http://www.youtube.com/watch?v=ts0jRvlfBX0

 

What's odd is that it doesn't actually cause the entire machine to completely freeze, it causes it to freeze one app at a time. And, there's absolutely no way to fix it that I can find, other than by doing a cold restart.

 

I've deleted the airport plist file at /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist and reset the PRAM.

 

I know there were discussions about this before ML was released, and I've filed a radr on it as well; but, I haven't heard anything back from Apple.

 

Does anyone have any insight as to what could be happening and how to resolve this (apart from just leaving my wifi disabled).
