I add these little references in so if someone in the future does a search and hits this same topic, they have a place to go for more information. We continue to evolve these knowledge articles as time goes on so there may be more devices that we can add to the environment list (or remove if new drivers resolve).

Thanks Alexandr P. <BR /> <BR /> I just wanted to provide more info on the process and how our articles are initially written. When an issue or question is presented or fixed, an article is written specific to that question/problem. Over time, if more issues are seen on other versions, hardware, clients, etc, then the KB article is edited and "evolved". <BR /> <BR /> If a problem is found on 5ghz clients and a specific version, it's written as such and then edited later as similar problems may be reported with different variables. <BR /> All input helps improve the collective knowledge! It is a large task and we are always trying to stay on top of it, thank you for being part of the process!
