    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Cisco 4.2.209.0 Controller Code Release

  

Cisco released a new rev for the controllers, 4.2.209.0. I'm not really surprised Cisco is still supporting 4.2. There are a number of large healthcare systems still on the 4.2 rev.

It's also no surprise 4.2 is still around because of its stability. Version 5.0 was a feature release train and version 6.0 is a maintenance release train but has proven to be riddled with bugs which are still being resolved. In most large enterprises stability is golden.
