We have upgraded all the APs on all of our network to 28.6. It's been about 2 weeks and it seems like they finally fixed the issue.   Although officially never acknowledged as an issue, I eventually got a message from Meraki support stating this is a known issue.

I suspect that has to do with the issue either. We are experiencing the issue even when clients are not roaming.

The issue has now been escalated to their development team.   One last thing; most of our devices are Mac laptops. I haven't been able to verify the issue with Windows machines. I wonder this has to do with the NIC firmware vs Meraki AP.   ... View more

Hi @zzzthump,   Has the beta firmware improved anything? I just noticed there is a 28.4 beta release and I am thinking of trying that.   We have a total of 22 MR42s and have been dealing with the exact issue for almost a year now. Super slow network and a lot of 802.11 disassociations with "unknown error", where clients are disconnected from the network.   Emre ... View more
