Hi,
thank you! I have enable 802.11r on meraki and now all work!
okay.....but thats likely to break other clients... and anyway, what you were probably seeing was the Android clients actually using wireless properly and the windows clients not. if you are not doing correct accounting session cleanups and handling the old sessions correctly (most of which is now done by eg NAS and controllers) then if you are forcing re-auth when roaming - which you are is you see a new RADIUS auth coming your way during such transitions...then you may have other sessions still open as the previous AP may not have said goodbye to the client just yet. you'll get used to this sort of thing - why the maximum count anyway? our average device count per user is currently 2.7 alan
