I don't know if the MikroTik hAP ac3 has been addressed with an issue. I picked one up. Its setup to mesh with OTA nodes. It will not start working the mesh to other nodes till you his scan wifi.To detect other nodes after a power cycle it will not detect other nodes till you hit wifi scan. Then it works fine to the next reboot.
Im running the lates nightly build.
