@GregasGYes, as far as I could tell that's where we were having our issues. Meraki support did a packet capture when I was on the call with them last week and I believe they told me they could see the pings coming in from one of our servers but they weren't seeing any reply going back out. ...

There were at least 3 or 4 VLANs experiencing the issue across 2 different sites and switch stacks. I checked a handful of others but those seemed to be stable. Meraki support asked me to do a packet capture of pings from a server on one of the affected VLANs to its gateway. I sent that over to them last week but I haven't heard anything back yet. ...

Probably a wise choice to hold off. I asked my boss if he had seen any issues with Meraki firmware upgrades in the past since this was my first time dealing with Meraki firmware upgrades. He said he hadn't seen any with the two he was involved with so I let the upgrade to MS 11.22 go through on 7/7.   Early in the week, I had some people tell me about some issues they were having with mapped drives disconnecting and I got disconnected from an Access database on a network share multiple times. After some investigating, I found that some packets to VLAN interfaces on the MS 250 stacks at each of our office appeared to intermittently drop. Pinging from a host to its gateway on the MS 250 stacks would be successful for a while then would start dropping for minutes at a time. This was happening with multiple VLANs while some others were unaffected. Meraki support looked things over but couldn't find a reason for it. At their request, I rebooted both switches in the stack at one of our offices to see if that would resolve the issue but it didn't.   I rolled back the firmware on 7/14 and so far everything appears to be functioning correctly again. ...
