3. Regards the mesh, well is the 2 proposed router set up above not classed as a mesh?
also what about double NAT?
do i need to be concerned with DHCP, DCP etc?
Can I turn off IPV6 or do i need that running?
Is there any more data on me adding the 3rd router/AP via wireless connection please?
4. 150mb download speed
Possibly about 15 to 25 devices i would estimate yet i dont know for sure until i get the full set up sorted so i can observe whats going on as theres always complaints about the speed issues yet im sure someone is consuming excess bandwith as only 6 people there yet if you was to say 6 people with laptops + phones = 12 devices + IOT = 6 more devices + a couple of guests and that should be full load on the network.
