I'm thinking of setting up a mesh network in my home. It's a single storey bungalow home with an L-shaped garden around the house. The main router will live in the garage at the front left corner of the house.

I pay for 50/20 nbn (Australia) broadband fibre to house. The TV (n maybe even my ps4) will be connected to the router via ethernet cables and it's only dead zones I care about n mobile tech like phones and laptops that exist in the house (like 5 devices only).

I don't really know how fast I need my router to be? I did a speed check and I get like 30mbps download speeds from my current 6yr old router. Will getting an AX3000 be any different to an AX1800 or lower given my speeds?
