The issue that has been identified has been confirmed with multiple wireless vendors as a known issue with recent versions of OSX - most notably Yosemite. The issue occurs most frequently when Apple devices roam from a 2.4GHz WIFI hotspot to a 5GHz WIFI hotspot. While there are benefits of operating overlapping 2.4GHz and 5GHz networks, ITS has opted to temporarily discontinue the use of the 5GHz WIFI spectrum until a confirmed fixed is released from Apple.
