WPA Authentication times out/failed every now and then but after some time succesfull
I experience a for me weird connection lost and reconnect problem.
I've Omada AP contoller (V4.1.5) that's controlling 3 AP's: 2 EAP245 and 1 outdoor eap225.
The use of the Omage AP control program makes sure the definitions of the AP's are identical as they're applied to all AP's.
So SSID's and WPA2 secure string is all the same for all AP's.
As of the installation begin of this year but now as of the juni release more ofter the WiFi is instable.
While connected and working client it suddenly looses its connection and attempts to reconnect.
Reconnect takes some time.
In the logs i see "WPA Authentication times out/failed"
But after a minute or so the client does get connected.
All type clients experience this problems: android, windows, chromebook.
The AP's provide 2,4 and 5 GHz using the same SSID.
I've reset the most setting back to standard.
I did orginally use Fast Roaming and band steering. Did uncheck them for now, that improved it a bit but not enough.
When checked these I noticed the client kept conencted but lost internet connectivity.
On android changing "using mac address to random mac" speeds up the relinking.
What could cause this behaviour and what to change here in the conguration ?
The DHCP is delivered using an Edgemax router. The DHCP logs do not reveal much here. Looks like the AP handshake somewhere fails within the alloted time.
DHCP is very busy, but seems the message does not pass:

I'm reading on the subject "WPA Authentication times out/failed" discussions on changing Beacon interval of DTIM period. Do not feel comfortable with this yet to start experiments.
In the mean time the customers on the site are getting upset on this instable WiFi.
Any thoughts?
