Also the same issues (around 40% to 50% authentication failures) on MR42 and MR52 access points since few weeks. Users are complaining a lot and we can't do anything for the moment tried to change the access point with no effect). Seems that it affects access points that are having a lot of other "noise" around them (even if not overlapping on the channels used by the access points).

Hello, Thanks for your answers guys ! Regarding the channel utilization, it is always pretty fine on the channels used by the access points (40 Mhz), so it's seems not to be related to a high utilization of the channels currently in use by the access point itself.And if i replace the MR42 or MR52 with a MR32 with the same channels, i don't have the issue. So it's seems related only to these 802.11ac wave 2 models and not especially if the channels used are highly used but also if all the channels around are high used (even if not overlapping with the channels currently in use). I was not able to test many things since lockdown but i have seen that in the release notes of the 26.8 firmware, an issue fixed can correspond to my problems: -> MR would get into a state where it would cease being able to TX frames reliably in environments with sustained high channel utilization (802.11ac Wave 2 MRs) This corresponds to the fact that my issues are only seen on these MR42 and MR52 (802.11ac wave 2) and not on old MR32. I will upgrade and check how it goes. Thanks !

Hi Philip, Thanks for your answer. I am already with minimum connect speed 12 Mb/s. When the problem occurs, the speedtest using my.meraki.com show a result between 0 and 1 Mbps. So users can't do anything in Wifi. We are using the 26.6.1 firmware, we had the same issue in 25.13. This behavior is seen only on MR42/MR52 access point. I don't have this issue with MR32 access point. Seems something related to MR42/MR52 model My only way to solve it temporarily is to reboot the access point.

Hello, We have replaced our MR32 for a mix of MR42/MR52 and since this change, we can see that performance (bandwidth) slowly getting lower and lower and almost tend to less than 1 Mbps. Only a reboot of the device permit to have good performance back for some time. We are observing this behavior in environment where there is multiple other SSIDs broadcasted by other third parties in the buildings next to us. We are in 5GHz only, 40 Mhz width channel. The 5 Ghz Channels used are not overloaded in utilization by other third parties. If i put a MR32 at the same place, same channels, i don't have the issue. It's like MR42/MR52 have an issue when the environment is used a lot even if it is not on the channels we are using. And, a reboot solve the issue for some hours (and we keep the same channels, so it's not a question of channels overloaded). We have open ticket to support but upgrading to last firmware does not help. Thanks in advance.
