@Adam_F wrote: It would also be nice if we can disable auto-firmware-updates on critical infrastructure Technically you can get Meraki to disable it.  Its extremely difficult and requires a very high level of approval by your Meraki SE and you better have a rock solid case as to why you need this disabled at an Org level.  In our case, we have scheduled quarterly downtime to upgrade MS, MR, Etc.  Given that we are a manufacturing company, and our sheer size, having to manage multiple models, hundreds of devices, at hundreds of sites.  The cadence of Meraki's software releases, end of support, etc is what sealed the deal for us.  For multiple years we ended up having to do upgrades outside of our quarterlies, which requires manufacturing downtime (millions of $ worth of production time); and our team was having to push work to handle upgrades, they disabled it for us Org wide.  So now we run X firmware until our maintenance windows, upgrade MS one window, MR's the next, etc.   If you really want to yell at Meraki, go read the firmware upgrade process on MS series.  Its an incredibly stupid design, where things aren't really verified before a stack begins rebooting, with basically only a timer being using to 'be sure' that downstream devices have 'had a chance'.  Without using staged upgrades, its very easy for a complex or large Meraki MS network to have upstream devices reboot well before or during a MS downloading or loading its firmware.   While for years we had near zero problems with firmware, the last few years have been lack luster. ...

We have the same problem with managed or unmanaged iOS devices.  The MR Layer7 firewall rule for denying 'online backup', iCloud is part of that. Access to iCloud is what is breaking text messages (iMessage) that contains pictures or a video.     ... View more

We are on 28.5 and have the issues.  Currently pending firmware upgrade to 28.7 or 29.5.1 depending on downtime windows which are a huge problem in our environment.     It's really bugging me the number of peoples sites that seem to have this problem and no real response from Meraki.  Also given that this issue seems to have been going on for quite a while, I would have expected it to be at least acknowledged by TAC. And that the minute I engage TAC since 28.5 is marked as 'critical' I get the canned "Upgrade the firmware" response is pretty annoying, as I point out the release notes do not contain any mention of this issue or an issue similar.  ...

I'd love to know how you rollback goes. How larger of a global deployment do you have? Rough number of networks and APs? Unfortunately, we dont have the option to roll back other than one or maybe two very small test sites. One of those would only have 1 client at best the other maybe 4-5 clients but only 1 access point.  Any of you that have worked with Meraki TAC do you feel like they are addressing the issue? Have you escalated to any Meraki SE contact?  ... View more

Did they suggest what firmware to downgrade to?  We seem to be encountering the same issues but have been on MR28.5 for quite a long time. Lots high density locations as well.. ... View more
