Hi Deco XE75 Pro specs seems missing IoT network & Device Isolation -feature on the specs list on your pages (link below), while Deco XE75 does have this feature mentioned. https://www.tp-link.com/fi/

I have been planning on updgrading my cordless network from my ISP providers cable modem WIFI to tp-link system. I need both 2,4 gHz and 5 gHz WIFI bandwiths in use and also wired cable for my desktop
