I’m using this http://forum.mikrotik.com/t/using-routeros-to-qos-your-network-2020-edition/66683/1 QOS2020 Optimized script, it works out of the box but I have two bridges: one for main network and other for guest wifi. I’ve tried to adapt it but when the bridge identifier mangle rules are enabler the other rules stop maarking packets thus making the queue tree useless.
