The release notes for MR 30.5 (beta) mentions "Intermittent connectivity loss for Windows client devices". Not sure if it addresses the problems in this thread but could possibly solve some of the issues.

We have a similar issue where our HA (MX84s) fails at random times. We have a case with Meraki but no solution in sight.

We had a similar issues with Radius authentication and the same error messages, "Client made an 802.1X authentication request to the RADIUS server, but it did not respond". After months of struggling we disabled 802.11w about a week ago and we´ve had no connection problems since then. Meraki support says a fix is on it´s way but no ETA yet. MR46s running 29.4.1. ...

The intermittent disconnects affecting clients on our networks was probably caused by a bug in 29.4.1 (link to another thread below) and the workaround was deactivating 802.11w until there is a fix available. We still see great numbers of 'excess frame loss' disassociations, especially on our SSID for phones (lots of roaming going on). According to Meraki support the specific description 'excess frame loss' is pretty new and would be expected in dense/complex radio environments and, in some cases, when clients roam.   If possible, try to disable 802.11w and/or the new client balancing.   29.4.1 Radius Issues some clients unable to connect to MR-53 AP's - The Meraki Community ...

Thanks for sharing. We have two SSIDs with iOS devices on one and Windows devices on the other. Getting excessive frame loss on both networks. Both networks are configured with 802.11w (enabled not required). Can anyone confirm if the setting of 802.11w to enabled affects the issue of frame loss? ... View more

Same issues for us after upgrade to 29.4.1. 5GHz only, eight MR46s, clients disconnect with problems to reconnect. Lots of "802.11 disassociation excess frame loss" in the event log. Both iOS and Windows 10 clients.  ... View more
