It sounds very nice but there is still one problem. It doesn't matter if it is Wi-Fi 4,5 or 6 there are still big problems in high isolated houses or rooms. Also WI-Fi 6 will not change anything on this point. Cable is still the best solution.
And reliability is the biggest issue. None of the popular manufacturers seem to be able to produce a router that both works well, is easy to use, AND is reliable and long-lasting. When I get ready to buy a Wi-Fi 6 router, my #1 will be reliability, #2 will be price, #3 will be performance.
