@NBAus I had same problem with controller version 6.1.0.19 ... after update to 6.2.0.17 serial numbers apeared on all devices

@memekritis I had eap connected to rb5009 directly before so yes it should work. I had no issue using it in trunk or access port. Also with eap in standalone mode and now with controller

Hi. I have rb5009 as router handling vlans and trunk or access ports works correctly with 2x eap and omada switch. So I would say its confing issue on mikrotik side.

@Vincent-TP Hi, My problem with mesh config is solved by support team. Flashed fixed firmware they provided and 5ghz works now.

Hi @Vincent-TP So I changed setting “None” to “external device” no difference My config for each VLAN dhcp pool address=192.168.10.1/24 interface=MAIN network=192.168.10.0 address=192.168.20.1/24...

Is it possible if signal from uplink device is weak lets say -66dBm than downlink device refusing clients on 5ghz network (mesh backhaul) ?
