I just gotten this router today and setup according to the black tubi method
I got mine from taobao directly, so AX3 pro for just around rm200 ( the pro got better external signal amplifier do choose the pro version)
You will need a manged switch like Tp-link SG105E , or Mercury SG105Pro ( sub brand under Tplink ? look the same even the menu is a carbon copy but cheaper in taobao , around rm50)
following the guide of black tubi to setup the switch, however do note, if you plan to use the switch function, another cable from router need to be connected to the free port. This is due to different VLAN.
So my setup is port 5 to router WAN , port 2/3/4 as switch , port 1 from ONU. I skip IPTV port since i did not use it.
then connect port 1 to router , any port from router to pc , setup PPPoE (unifi acct + password) , setup Wifi as per normal and you are done.
the interface is rather simple , so there are not much mess around with. There are no CPU / temperate / client list like Asus , so its really basic. So I cannot tell how is the performance really like on high load.
You can translate to english after its connected to internet.
PS : there is the "user experience improvement program", like how facebook /google. It however state the data may be provide to government(china) if requested. Make sense in china , not in malaysia , so please turn that off.
thanks ...
