We have users experiencing disconnections or roaming issues. Attached is a sample from one user.
APs are CW9166I, and clients are a mixture of devices (iPad/Apple TV/MacBook/HP Win11)
The environment is 2-story middle school with an AP in every classroom or office/media center. Students have iPads, but again, this is not device or OS specific.
The 29 APs are running two 5 Ghz radios, and many of the roams are between the two radios on the same AP.
We experience a high number of unexplained disconnections, too.
The environment is RF clean, and the Meraki dashboard indicates that channel utilization and interference are low.
The APs are new, and we had been running MR42 or MR52 since 2018 without issues.
The first thing I check these days is whether the customer has an "RF Profile" configured. It solves about 90% of the issues immediately by creating one.
I mostly use the "Open Office Profile", but in your case the "Classromm Profile" might be best.
Make sure you make the profile the "default", or apply it to all your APs.
And while you are there, make sure you turn on AI channel planning and "busy hour".
