This new speed really made me discovered a lot of new stuffs about mesh system as I wasn't really active in reading up about Wifi6 and mesh and the latest technology.
After thorough consideration, this mesh thingy is not cheap to replace.
And not all Easy mesh certified by TP-Link or Mercusys can be pair with ethernet backhaul.
Initially, I thought by simply purchasing a good TP Link router and another 2nd hand used tp-link or mercusys router (function as satellite/AP) I will be able to pair up with ethernet backhaul with any easy mesh router or any AX rated router will do the job but unfortunately , after much reading, not only does it not support but is a case to case basis and firmware dependent kind of thing
So in the end, I choose to look at TP-link deco series, but also found out, those deco models doesn't link back with a TP-link router .
And with a budget of RM300, i think Fiberhome is my best option of a router/satellite/mesh with ethernet backhaul support for now.
TLDR;
Initial plan, get a new Mercusys Mr70x or TPlink Ax53, pair it up with AX10/20/23 with ethernet backhaul under EASYmesh to create a mesh network so that I can enjoy roaming and self healing. But ax20 doesn't supports easymesh on firmware, ax10 seems to be fairly limited and some commented when link up with ethernet will cause the device to hang.
When it comes to networking right now you kinda get what you pay for larh.
