Test on another device and always ensure you’re using Ethernet to test with also.
I can't stress this enough. Telstra + Opticomm fibre have only just released 1000mbps/50mbps profiles over here (previously on 250mbps/25mbps). I had a Ethernet over Power as the ONT is in a really poor place. The Ethernet over Power supports gigabit ethernet and in theory 2gpbs over power lines.
Didn't notice any issues when on the slower profile however noticed that I was maxing out at 300mbps/50mbps after the profile upgrade. Put in a 30 meter ethernet cable and now I'm at 950mbps/50mbps over ethernet. I did some speed testing on Wifi in various rooms and found that it was maxing out at 600mbps/50mbps.
