The most cost effective way to get consistent and fast internet is over a wire. My rule is that if it doesn’t move, and if it has an ethernet port, it gets a wired connection. TVs, gaming Consoles, the laptop that lives on a desk/table…this stuff. Then the stuff that does move or can’t be wired to a switch can have the wireless bandwidth it needs. So, OP, you need a box of Cat5e spec UTP cable, a bunch of ends and the tool to put them on the cables you make, and a switch or two with 8 or more ports each. Next is to find wireless access points that are wifi6 and capable of covering your home. 2000sqft can usually be covered by a single unit of any top tier routers from most manufacturers. I’m partial to Asus for home use. After this, it’s a matter of configuration. If you have many neighbours, turn off the 2.4GHz band radio (if possible for the wireless-only clients). If you don’t have wifi coverage where you need it, add another WAP (NOT a mesh node) - it’ll be easy to deploy with a wired backbone infrastructure already in place.

I have made Brave the default browser on my phone and it integrates pretty darned well with other stuff

Run the ethernet cable, add a switch to connect your two machines over 2 more wires and you will never experience internet problems, except perhaps with your phone.

Do you have an old router kicking around? If you do, it’s possible it may be reconfigured: Asus calls it a Media Bridge, where it becomes a wired switch with a wireless connection to a router. I did this for an old laptop whose wifi card died, and the user is thrilled with the speeds being ~3x what they were. No holes or fishing cable through walls required.

Sigh. There’s no way you’ll ever get 1Gbps wirelessly. None, ever, period. If you’ve a Cat5e cable run from the modem location in the basement, run a 2nd one. Place the AX router on the main floor (first ethernet cable) and then back down to a switch in the basement (2nd), and run more cables around the house from there. For a few hours and a couple hundred bucks, you’ve just added a few thousand dollars of resale value to your home in modernizing it to be networked.

Telus Fibre? I think you need to take a step back and tell us how you’ve got your network configured. Telus ONT to their gateway to your Archer? Is this a double NAT scenario? Have you tried taking their hardware out of the path and having your archer handle the authentication?

I’ve been having tons of fun in my place running and terminating UTP. It wasn’t fun until I figured out that everywhere I wanted/needed an internet drop was somewhere that either had an RG-58 cable run or 300-ohm twin lead run to it. Following those (and in the case of the twin lead, replacing it with modern infrastructure cabling) has added value to the home and taught me a new skill that I’m quickly gaining confidence in using beyond my walls- I’ve even helped a cousin put a few new drops in at their place too!
