I have one site with MR52s (21 of them in total) and last week (after a few months of operation with no issues) they started to reboot randomly each day, maybe twice a day, one of them half a dozen times.
Not all of them, just 4 or 5 of them were doing it. These are between different switch stacks as well (WS-C2960X-48FPS-L), so plenty of power. Went from 25.11 to 25.13, still rebooting randomly.
Testing with support and we upgraded them to 26.X and now about 10 of them are rebooting.
I'm actively working with Meraki support who is very helpful, but just curious if anyone else out there is having symptoms like this? Solutions?
I guess you tried factory defaulting them?
Maybe you could try moving some to a different network temporarily with a minimal (or no) configuration and monitor them for a few days to see if they still reboot. This may help rule out a software issue vs. hardware.
I don't recall any MR52's that I look after, but I have not had that issue with any other MRs. Having said that, I'm not sure I would notice the odd AP rebooting, especially if they only do it one at a time.
Not with MR's - but I have seen Meraki devices in the past (rarely) get into a slow infinte reboot loop because the cloud thinks there software upgrade failed, and keeps repeating it.
The dashboard reports the software version the device is meant to be running, not the software version it actually is running, so only support can diagnose this one.
So perhaps you could ask support to verify the actual code version running on the AP, as opposed to what the dashboard is reporting.
Yes I've tried doing all kinds of things. Cables verified as well. Multiple firmware versions confirmed by support. Everything was fine for months until last week and then some of them just started doing this. I'm now digging into the 2960s to see if there is anything there (nothing yet so far).
Now it looks like this, which is a week long view of some of them. Some worse than others.
This might be too hard to do; but if you swap a problem AP with a non-problem AP - does the issue follow the AP or stay with the port where it was plugged in?
Has your part of the world experienced any lightening storms recently?
