There are new Asuswrt features causing issues with excellent add-ons from the past.
I'm sorry, but Guest Network Pro may be propagated to... some nodes, but
YazFi was much easier to use, simpler and with more useful features. Not to mention how many people praised
FlexQoS for gaming, streaming, etc., how much time the developers invested to make it better than ever and... now Adaptive QoS is just broken on the new routers. This work-in-progress building of "pro" features on top of limited and unpredictable compatibility "mesh" black box caused disturbance in regular user base, custom firmware users and scripts ecosystem community.
