I don't agree. I had a Wi-Fi 6 router. I tried several WiFi 7 routers and the speed in my home network doubled.But if you need WiFi 7 over 6E then those routers won’t suffice. WiFi 7’s real world benefit is only noticeable in heavily congested wireless networks.
If you think you need WiFi 7 at home, just stick to 6E and have a professional advice you on hardware and placement. That will perform infinitely better than a random nerd installing an all in one router.
