We have the same, we've started noticing it a lot due to change of our zero trust solution, when users 'lose' connectivity they see the disconnection pop up. I say lose, I've had it myself around 5 times today but we aren't seeing timeline showing disassociations in client timeline view, and the client itself doesn't show a disconnection (checked using netsh wlan show wlanreport.) It would appear it's a loss of Layer2 and above, the radio is up but no data across it for a brief moment which is tearing things down. Here's my own laptop for past 24 hours where I've had multiple drops but as far as Meraki eventlog and timeline is concerned all is ok We're around 99% confident rolling back to 28.X fixes on, on two smaller test networks, one with about 20 devices on firmware 29.5 on Monday had around 60 excess frame loss messages, but also a lot of "unspecified reason". Rolling back to 28.5.1 (for some reason 28.7 isn't available to us) that went to 3 for the entire day, which I guess will happen at times if users move far away from an AP with nothing to roam to We've tried client balancing on and off, with it on we see very erratic roaming, my boss was on 4 different APs in about 30 minutes, bouncing between two of them constantly. At one point, physically his laptop had 4 APs in a line from him, and it was associating with the furthest away at around 150 foot, but there was one 20 feet from him. Around 250 clients in building with 24 APs, 16 of them in the office areas in that example We have a mixture of models and site sizes, MR33, MR42, MR52 and MR44 (MR44 being the bulk) - 15 users, 30 users, 250 above, doesn't make a difference We see the issue across the all sites and sizes, personally us (the internal IT) have the issue, all Windows devices, to be specific Dell Latitude 7300/10/20/30 and 5420. But we see it for MacOS devices, Intel and Apple models, iOS, Android and some static devices such as HDMI sticks running display boards Planning to revert back Monday evening globally. Will update on what we experience in the few days afterwards, it will be pretty apparent to us if it fixes the loss of connectivity. Shame, the client balancing change in 29.X sounds nifty
