hi... looking to grab either a ax6000 or ax9000,
need a vpn able router than the singtel ac plus router.
(bought a china set roborock which is too new.. no unlock mod online. i read might need a pptp to get pass the region lock)
am using samsung connect home as mesh but it shhhiiiitt..
2 storey approx 140sqm.
can advise if i should get 2x6000 or 1x9000 (maybe near future can add additional 6000 for extension?)
should i get the china set or local set?
No idea what kind of VPN you need for your Roborock model. I highly doubt PPTP (or L2TP) based VPN can work. In fact, you may have to buy VPN solutions like Transocks or Malus if you need to get IP address from mainlan China. And these types of VPN will not work on normal router, rather you have to use your Windows machine to bridge the wifi connection, which may be a bit complicated.
As for Wifi mesh solution, are you able to use Ethernet backhalu? If not, a pair of Xiaomi AX9000 (triband) is recommended. You should go with global version with local waranty in that case as a pair of Xiaomi AX9000 is not cheap.
If you are able to use Ethernet backhaul, then it depends whether you want local waranty or not. Xiaomi AX6000 does not have global version. I will recommend to get a pair of Xiaomi AX3000 (or Xiaomi AX3200) local version first. If the coverage is not that good in certain places, get more units. Or you can get Xiaomi AX9000 (main router) + Xiaomi AX3000 (mesh node).
