Wired and Wi-FI speeds are 2 very different things. NFtoBC nailed it, has nothing to do with Telus really you are getting gig to the router, if you are able to wire in you will get full speed.
I use the Actiontec for Optik and a Netgear Orbi for my wi-fi and it works great, so you can still use your google mesh system for wi-fi and keep the Actiontec, I have had zero issues and been using it for over a year.
