As mentioned in another thread by @AnythingHosted 27.3 has been released and has the below fixes and issues:
I received an email from Meraki support at 17:03 (UTC+1) saying that all my 27.2 networks would be upgraded over the next week to 10 days, so they must be pretty keen to bin 27.2!
Wow I thought I was going crazy. Ever since 27.2, all sorts of Apple devices have been doing this while connected to my MR42 but not my MR56.
Overall though the 27.x series seems golden if you have WiFi 6 APs. The MR56 easily got 20-25% faster aggregate throughput with my devices compared to 26.x, which is making them perform more comparably to consumer high end mesh routers like the 8x8 Orbi.
(I know in an enterprise world we might laugh at those devices, but those expensive consumer products seem to perform extremely well)
Excellent @CptnCrnch , it has gone smoothly for us so in summary it has been installed on:
Not bad I'd say 🙂
I got the same problem with 5x MR52 and one MR84 thinking that my Apple devices was hardware fault, changed motherboard on one MacBook Air Retina explaining at the Apple store that the physical wireless layer link speed between my Apple device and the Meraki AP was random dropping less than 13mb/s...
Back from the Apple store with a new Mac and same problem, crazy....
Did 27.3 fix it for you? I was surprised because the release notes made it sound like a small set of legacy devices but I saw it across 3 of the latest generation Macbook Pros, the behavior went away after the 27.3 update.
That seems like a different problem. The bug I was seeing was that these devices would totally stop passing traffic, not just slow/intermittent performance.
