Some APS offline after Internet connection restored

Scenario:  All switches (MS390s running beta 15.9) and APs (MR46 & MR56 running 28.6) were online in the dashboard.  Our Internet connection that supports 6 schools was bouncing this morning - enough that all devices were offline.  After the Internet connection became stable, all switches are now connected to the Meraki cloud and showing online.

 

However, some of the APs across the district are showing offline. 

 

What is the best way to get the APs back online?  In the past, I have cycled the switchport the AP is connected to.  This is fine for a few, but approximately half of the APs at each school is showing offline.  Shouldn't the AP try to reconnect?  Internet connection has been restored for about 2 hours now.

From Meraki:

There is an internal ticket that was opened about MRs on Firmware 28.6 losing cloud connectivity.

 

All the APs are back online now.  The reconnect process took longer (4 - 5 hours) than I expected.

Kind of a big deal

Hi @A4WanMan , whilst they’re still showing as offline the APs will still be active and passing traffic locally to clients.

 

Have you tried giving one AP a kick and seeing what happens?

I'm not an employee of Cisco/Meraki. My posts are based on Meraki best practice and what has worked for me in the field.

The APs are mounted on the celing grid.  I can't kick that high. 🙂

 

What do you mean by "giving an AP a kick"?  If I go to the switch port where the AP is connected, cycling the port usually brings it back Online.  I have had to disable/enable the port and POE.

 

I have about 130 offline across 6 sites.  That's a lot of kicking and clicking.

Head in the Cloud

I'm assuming by giving it a kick, @UCcert meant power cycling one AP to test and confirm whether that brings it back online.

 

The AP's should constantly be trying to reach out to the cloud. Do you have any not connected to MS390's? Given they're fairly flakey and are running beta code I would initially be thinking they might be an issue.

 

A couple of other things to check, is the AP"s MGMT IP reachable within your network? Can you do packet captures to verify the AP is sending packets to the Meraki cloud? I can't remember if capturing of the AP"s LAN interface will capture management traffic.

I am also suffering from this same issue since moving to 28.6. I see there is a 28.6.1 firmware now available, have you tried that one to see if it fixes the issue?

Getting noticed

The release notes don't mention that being fixed.  Just new device support.   I just posted a similar issue.  All MR46 / MR55.  MR42's don't seem to be impacted.   They do pass traffic, but a true PITA if you have a lot of devices to manage.   And its not just comm losses that cause it, but is very much a catalyst if you have a comm issue.    Ticket is in Engineering as a NextTunnel issue.   We see them drop across the country at the same time, so unless Meraki Cloud is having hiccups, not just a local communication outage causing the  issue.
