First of all I would check the MAC address table entry for this port several times, especially when it is dropping to understand if the issue is related to changing VLAN or something else.
Is there any SSID running on VLAN 226?
The log messages could be the root cause if your issue but also the result of something else for example AP disconnecting.
Is the AP powered by external source or PoE? What is the AP?
RSTP or STP would normally erase MAC table entries when TCN BPDU messages are received by switch. You may want to ensure all end devices' ports are configured as edge device for STP settings so less TCN is generated.
Thank you for the reply. When I logged into the switch and did a mac address table entry It stays there. I used my mobile phone to test this. And after the drop its not there. And as soon as there is data again the phone is connected to wifi.
