Information About Aironet Extensions Information Element
The Cisco Aironet Extensions Information Element (IE) is an attribute used by Cisco devices for better connectivity. It contains information such as the AP name, device type, radio type, AP load, and the number of associated clients, in the beacon and probe responses of the WLAN. The Cisco Client Extensions use this information to associate with the best AP.
The Aironet Extensions IE configuration is disabled by default. With this feature you can set the AP name not through enabling the whole IE extension, but by just inserting just the AP name.
