sorry first time using this forum... more info below:
particularly when roaming between AP's - have a number of reports of users Macbooks spontaneously showing the wifi exclamation mark icon. Looking at the client association in hivemanager they remain associated throughout the entire day to the centisecond, even when roaming to adjacent APs.
APs are 550's, heat map shows adequate coverage. Can't replicate the issue on a Wintel device.
