A very very important note about @mikrotik CAPsMAN.
There are two different WiFi "stacks" for RouterOS: wireless and wifi-qcom. Both provide CAP/CAPsMAN but they are not compatible. A CAP device using wireless package can't talk to a CAPsMAN device using wifi-qcom (and vice versa I guess).
For example, cAP Lite runs on wireless package and to control it from RB5009 you need to install the wireless package on the latter!
