Also a good note on my own journey, is that don't use speedtest.net (or shaw speed test) in a browser use the app instead it's more accurate at high speeds.
Ookla (speestest.net and shaw's speedtest) don't recommend using the browser with speed close to Gig and more. The say use the app.
In a browser I get 549.10Mbps down, on the app I get 848Mbps same computer same server (Shaw Calgary).
