Actiontec 3200 Slow Speeds

[wireless]

Seeing abysmal download and upload speeds with my gigabit fibre, started on Monday. Down is anywhere from 120-390mbit, up goes as low as 80mbit and as high as 300mbit.
Spent an hour with technical support on the phone the other day, and no resolution. At the time I had my dns set to 1.1.1.1 and 8.8.8.8 which the tech wanted me to change. That has since been changed, and unsurprisingly has not resolved my issue.
I have powercycled the actiontec 3200 router with no success, I am hardwired to the router using cat6. However from the attached screenshot you will see it is the speedtest at the router (so no computer involved) that is showing poor speeds, tech support didn't seem to be understanding me on that one.

Anyone have any ideas or how best to further escalate this?
