To add why you want to disable aironet extensions.
It is reccomended in hotspot environments and environments with mixed vendors and some perhaps with old wireless cards, OS or drivers. Aironet extensions may have negative impact for some clients to connect. A little real-life story. Probably happened to many here: I recently had a customer case where the guest wireless was not working on an open network. They wouldn´t finish dhcp negotiation. All other clients worked fine. This was the first issue in many month but after investigating the clients pc had driver since 2005 and could not be updated at the time. I also noticed that on the guest WLAN (Wireless Controller) had aironet extensions enabled. Immediately after I disabled Aironet extensions on that particular SSID those clients worked fine. regards.

J?nner 2011 20:15 An: [email protected] Betreff: [CCIE Wireless] lab 3 question 3.7 - aironet extensions. Hi all, Can anybody explain why you would want to disable aironet extensions to ensure that clients cannot get the name of the AP? According to the IOS config guide aironet extensions are responsible for world mode, MIC and limiting power on associated clients, so I'm not sure how that fits in the solutions guide. I would think no cdp enable would take care of ensuring clients cannot get the name of the AP. Any help is appreciated.
