Hi. I am getting my Zen Wi-Fi XT8 mesh system with 2 routers by tomorrow and it will replace my existing mesh system which is an AC5300 and an AC68U connected via Ethernet forming a mesh system. My question is that once the new Zen wifi xt8 system gets installed can I add the existing AC5300 wirelessly to this mesh system to fill in dead spots ? For example the zen wifi system routers will be placed at 2 corners of my home connected via Ethernet (backhaul). In the Center of our home is the kitchen where I wanted to place the AC5300 router but it would be connected wirelessly as I don’t have the provision to run an Ethernet cable. Will this system work together as a mesh and would there be any issues using the Zen wifi 6ghz system and the ac5300 5ghz system together ? Hope my question was clear ? Illustration attached for clarity.Thanks.
