Hi @aous.salloum
Don't think so.
By definition:
"Aironet IE is a Cisco proprietary attribute used by Cisco devices for better connectivity. It contains information, such as the access point name, load, number of associated clients, and so on sent out by the access point (AP) in the beacon and probe responses of the WLAN. The Cisco Client Extensions (CCX) clients use this information to choose the best AP with which to associate."
So, this is an additional field on beacons in order to try improve interoperability between AP and client. It is useful for Cisco IP phone and can be a problem for some non-cisco clients. Usually I disable it.
I really don't believe you can have problem in mesh by disabling it.
