You're the only video I've seen so far that actually tests it. This video should be on top of search results. It was 10 videos down.

We got the 1gb frontier plan and instead of giving is the erro we got their own branded one which was terrible range/speed. Ended up not using it and bought a tp link deco e75 pro with wifi 6e and a 2.5GB WLAM and LAN port. Plugged it in the ethernet port on the back of frontiers black ONT much much better getting over 700 to 800. While it is a bit pricey its worth it

Honest thorough Review ❤

Hi Jonathan, (well let's see if this comment gets deleted) Great review and information video on the wifi 6 eeco extender 👍. I have Spectrum cable Internet with wifi access point 200' away (pole barn) and get very good signal and speed no dead spots. Ranch house with full basement. Thank you for all your great videos help, information and reviews. Al

Try leaving the wifi extender upstairs but on the other side of the house away from the router
