Yeah your right, but..... wifi 6 is a game changer baz, alot of new boxes coming out have wifi 6, new laptops, phones, tablets ect... have wifi 6 and my god is it fast, its great for solid wifi all round the house. But obviously means upgrading routers, devices if you want that, not everyone can do that but if you can then I highly recommend.Wired is always better in some instances as it’s direct from router to device and right ethanet cable and port from router.
It’s a kind of swings and slides things as what works for some won’t work for others personally I use an Ethernet all time on most things.
WiFi will be better for some and better speeds but no doubt about it there will be a black spot where signal is weak so ethanet maybe required.
I’ve Amazon original ethanet adaptor and works really well out of 35mbps I get 33.2mbps give and take the loss in speed.
But no one has asked the op what speed test he is using to test his speeds whether it’s ookla one from the IPTV app been used or that analytics I think it’s called which I find that more reliable then others mentioned 😅😅
