5GHz frequency range supporting 100Mbps Ethernet connectivity
It looks like the router’s high speed isn’t fully used because it only has two Ethernet ports, each limited to 100 Mbps. The 5 GHz band and 867 Mbps peak speeds are more for future-proofing or testing than practical daily use.
You're asking if you really hit those speeds using a 5GHz network, but your experience was only about 80 megabits—especially far from any signal.
I'm not sure if I can fully use the 867mbps bandwidth, but I believe I could reach around 300+mbps with a 5GHz connection. In such scenarios, only about 200mbps might actually be usable.
I've only noticed such low speeds on mediocre routers like the BT HomeHub 5, which lacks a strong enough CPU for good AC performance. On my laptop I consistently reach over 300Mbit and up to 500Mbit when using FritzBox with OpenWRT. For routers featuring 100Mbit ports, it's highly unlikely their CPUs can handle full-speed AC; however, in theory you could still gain from WiFi speeds being faster than LAN, even if that sounds a bit silly.
