The switch is not blocking p2p . If you use bridge mode on AP, and make sure the AP firewall allows it and L2 isolation is disabled

We've been having an issue where our ISP has had a number of fiber cuts, but when service is restored our meraki devices go into a state where they drop 20-80% of packets until we reboot every switch. The original issue is obviously the fiber cuts, but would this bug be related to the packet loss after restoration? Topology wise - main office has two MS350s running MS11.30, and each branch has an MS250 and some number of MS225s?

I considered that but the issue wasn't there with the Cisco branded SFP and looking at load its not anywhere near what should cause any issues. Yes, my first step (after replacing the SFP) was to update to the just released 11.30 code....no change. I would have to verify what fiber is in place, it was here way before I was but this particular run is probably only about 150', not a long distance by an means. The Meraki SFP is this model FTLX1371D3BCL-C1 (MA-SFP-10G-LRM) replacing the Cisco Part SFBR-7600SDZ-CS3

Discovered I had this issue today and after lots of mucking around (over several hours), removing the wifi adapter in Device Manager, along with the current drivers for it, and re-adding it via a scan (as described above by michaelpersaud ) fixed it. My Macbook booted into OSX 10.14 initially connected fine to the Meraki AP and another AP we have at home, and browsed sites fine on either SSID from either AP. When booted into Windows 10 the device was fine on the other brand AP, but while it connected to the Meraki AP and got an IP (DHCP), gateway and DNS address fine (and could ping stuff on site or off fine) web pages would take minutes to load, would partial load or wouldn't load (Chrome and Edge) The replacement of the wifi adapter drivers has pages loading snappy again via the Meraki AP. Note that my iPhone on the Meraki AP seemed fine (Safari as browser). This issue may have surfaced days or even weeks ago without me noticing, this device (if in Windows) is usually on ethernet and not wifi. Thanks for the suggestion and assistance folks !

One thing to remember, especially with Dell laptops, is that the OEM uses some proprietary software/drivers that don't always get along with WAPs. If a Dell has the "Unified Wireless Driver" software (or whatever it's called), you should definitely uninstall that POS software, uninstall the driver, reboot and let Windows reinstall the drivers. Unfortunately, most of the time you won't be able to update the driver and are stuck with whatever 3 year old driver Dell has released. I refuse to use HP products, so not sure if they're still as bad as Dell for that.

@Frankthetank wrote: So with this new licencing structure what exactly happens if you have 5 active devices on a network and 1 of those devices licence expire and the 30 day grace period runs out but all other devices on the network have current licenses? Will you shut all devices down in that organization? As a network administrator I recently had this happen due to a issue with a camera license and our entire Meraki network was taken offline due to 1 expired camera license which wasn't stated very clear that that would happen and is in my opinion ridiculous. @Frankthetank In co-termination, we do deactive/shutdoewn the entire organization, but in per-device licensing, only the device that has the license issue will be deactivated. You can read more here.

Also make sure every single access port (connecting end devices) on your switches in your entire network is running in portfast/edge mode. If you don't every time a device turns off or on you will get a TCN flood in your network causing shortened MAC address lifetimes.

I have several MS425's in production and not experienced anything like that. I have; however, experienced where one particular one seems to go offline briefly and randomly after we had big power outage on that side of town. I had thought it to be a power issue with the switch, or potentially a power supply...but after verifying I have good power and swapping power supplies I have wondered if it were something to do with a Cisco switch in this network and PVST (see other thread about all this). Never did I have to do a hard reboot though, so doesn't sound like this is your issue.

Sorry I forgot to update this. i guess I found the issue, at least for us. I only have MR42’s so could not test with other models; however, I tried multiple boards, aps, rooms, schools, etc to no avail. same symptoms as you describe with the particular model board. The only thing I found to make it work was to set my channel with to 20Mhz for that SSID and I Haven’t seen it return—-I’m surprised you say it returns for you after that change. we just started getting in new boards with a google device powering it and no issues at all. Ironically the new boards have a built in android hardware and the issue is on that hardware, but not the attached google hardware

Well 26.6 is stable release candidate now as more people have deployed it. If several of you upgrade to it then it will be stable...

For me the Meraki DHCP is great, easy to use, and pretty fail safe from my experience. However, no P2P means some Apple functions (and others I'm sure) will not work.

I have the same situation (although on a much smaller geographical scale). 40 separate buildings with people sometimes traversing between them. One organization, 40 'networks' beneath them, an SSID configured identically between all 40 buildings to allow those folks to roam.

If the comparison is "apples with apples", you you use SmartNet and DNA licencing with the same terms as the Meraki licences - the Meraki solution usually works out wayyyyyyyyy cheaper. I haven't done a WLC for a while now. I think DNA licencing is compulsory on them now, every if you don't have DNA Centre.

As was said, and also how much do you really want to support. I have roughly 900 seat auditorium (2 stories) that I have to support in the school system I work for but its not a priority room, meaning if we can reasonably support guests then its fine. If 900 people crowd the room and they all have at least one device and they want to stream a 4k video, well we just simple don't feel it necessary to support that. I have 5 access points in there, 3 serving the bottom floor and 2 serving the top floor. No, it would not support everyone all the time but it adequately handles what is mostly in there.........which is an occasional event with a percentage of people on their phones playing on facebook on my guest account. We did have a teacher event one time where we had a large crowd full of tech savvy teachers showing off their new tech toys (and I have pic to show this) and they complained about some 'slowness', but they all managed to do what they needed.

There's definitely no need for as many as 8. It's me getting it down beyond 5 is the big concern. We have to have separate ssids for Students, Guest, Teacher/School Assigned Faculty, District Staff & Non School Assigned Mobile Devices (Each have different access levels regarding Content filtering and bandwidth). I think 5 will be a good start for me at least.

This topic is similar: https://community.meraki.com/t5/Dashboard-Administration/Chromebook-DNS-names-in-dashboard/m-p/61008?search-action-id=12499492061&search-result-uid=61008 And @chuyendang shared a nice google sheets script in there. That may help. I haven't tested it though.

I use the Google authentication method for our BYOD devices and for some reason lately some devices (phones mainly since that is what usually is on it) just randomly disconnect. Not to mention each time a user enters a new building (which is a separate 'network') they have to re-authenticate. I'm not sure if that's a problem on my end or Meraki, but it would be more frustrating if that were the authentication method for essential devices.
