Videotron themselves tell you not to use their own site, because it can't provide enough bandwidth to reach giga speeds. I used various servers on speedtest.net, and then tested indepedently by downloading files from gigabit servers to a single device, and then to multiple devices (aggregating the total speed)
> Also, the browser you use can make a difference and any Antivirus / firewall program will also affect the result. I did a few tests on my computer and I found out Firefox is usually less affected by my antivirus program than Chrome or Edge.
The issue is not browser or PC (CPU)-related - confirmed by Videotron techs
My particular issue is 100% that the modem cannot reach gigabit speeds at the moment, at least not in my house it can't. That's why I was looking for proof of someone with the same service having actually reached gigabit speeds
