We received a reply from support earlier this month,   "As this is a known issue our development team continues to look into this issue but there is no current timeline as to whether this issue will be resolved in the upcoming MR firmware stable, however the dev team is aware of this issue and looking into a resolution."   So, it does look like they are aware of the issue and doing something about it. We have restored back to version 28.6 and have had zero issues since. There have been some good recommendations within this thread as to adjustments to make to allow the current version to fit your needs, if you need to take advantage of any of the new features in 29.x. ...

One tech recommended this, the other didn't. I saw others try to go up in firmware with the same issue still happening. I have not tried 29.5.1, but have read the release notes and it doesn't mention fixing this issue specifically, just "general stability and performance improvements". Most say that so I'm not going to roll forward unitl I see more from Meraki. We have a lot of iPads on the network for maintenance staff and I can't adjust the NIC settings on those, and they are mission critical.    We first noticed the issue on IOT devices monitoring temp/humidity throughout the plant as well as iPads/tablets getting disconnected randomly. Devices would show disconnected to load balancing in the error logs and the AP's would show the excess frame loss error. It was happening in our plant with a high number of AP's, also mentioned earlier in this thread. It eventually showed up in our smaller plant so AP concentration may/may not be another factor. ...

It did fix all stability issues for us. We were seeing the issue more in our higher concentrated AP location first, but it eventually did show up in our lower concentrated AP location. We were unable to roll back ourselves as it was past the 14-day threshold to do so. But support was easy to work with and scheduled it for the time we chose. Only caveat is they will only schedule on the hour. Rollback of 35 AP's took about 15 minutes. ... View more

We've talked to two different techs about the issue and while they acknowledge they have gotten an influx in calls about the issue since Christmas, I haven't heard an official position from Meraki, only "it's been raised to engineering to review". We have rolled back both of our sites to 28.6 as having 50% or more of our devices bouncing regularly is not an option. ... View more
