I saw something strange.
My network speed is not ideal, since no client can get more than 54 Mbps, on 2.4 Ghz, and 5 Ghz.
The access point is in an open space, and all clients are in the 5 m range.
My modes on the access point :
2.4 Ghz >> a/b/g mixed
5 Ghz >> a/n/ac mixed.
In attachment you can see that the connections are good.
My controller is version 3.0.5 (updated from 2.5.4 to 3.0.2 to 3.0.5)
My EAP 245v3 has firmware version 2.0.0 Build 20180601 Rel. 52885
Anyone an idea?
Server/controller and access point are already restarted.
