With regards to the B818-263, it was a good speed bump over the CAT6 TP-Link Router. Limited interface and not many options to tweak. It had an annoying habit of flicking between masts at its own choosing. It took me into ~160Mbps download territory though. I've recently moved over to a new Zyxel 5G Router, and depending on which mast I connect to (as you can control the bands in the Zyxel) I can go from 250 - 400Mbps download (on NR 5G). Upload varies between 20 - 30Mbps. And that is using WiFi, if I was cabled, I may get a bit quicker.
