Since the last two updates of my Deco XE75 Mesh network with 3 pods the WiFi network is quite unstable. It constantly dropping WiFi clients from the network and after a few seconds they are connected again. This is very annoying because my AppleTV and HomePod Mini are part of this Mesh network and HomeKit constantly report that these devices are not available anymore and within a few seconds message pops up that they are available again.

I switched to 2.5 Ghz for these devices and disabled beam-foaming and fast-roaming. I also switched of Mesh functionality for these two devices. But with no result, these devices keeps dropping connections from the Deco XE75 mesh network.

Created some notifications in the Deco app to send an e-mail when one of these clients disconnect and connect to the WiFi network. I received the following mails from the Deco network:

14:45 TP-Link Cloud, Device Disconnected, AppleTV is disconnected from the AirMax network.

14:46 TP-Link Cloud, Device Connected, AppleTV is connected to the AirMax network

15:21 TP-Link Cloud, Device Disconnected, AppleTV is disconnected from the AirMax network.

15:22 TP-Link Cloud, Device Connected, AppleTV is connected to the AirMax network

When looking into the log file i see the following messages at the time of disconnect and connect of the AppleTV (EC-A9-07-1F-17-59)

It seems that the device is not in th arp table anymore and when the disconnect_counter reaches the value 2 the device is marked as disconnected.

Does anybody has similar disconnection/connection problems with their Deco XE75 with wifi devices or any advice what to do?
