I am glad I am finally talking with someone that does have ideas and does know about technology as it has been very frustrating trying to get people to understand what is going on.
With that being said, to answer your question, yes, both other location I have tried are both Rogers customers, both on the exact same package as me (i.e. 250 fibre - 250 up - 20 down) and both have the exact same modem, Hitron CGN3. This is one of the main reasons I am thinking there is something specifically assigned/throttling my particular account.
I know about the ISP disputes and of course the software/service provider disputes (i.e. Netflix, etc.) currently going on but you would think if that was the case it would not just happen at my place but also at the other two locations I have tried. On top of this, if this was also the case, I wouldn't think my home would be consistently slow and the other two location consistently fast (both locations always show between 180 - 200).
I honestly don't think Rogers is performing any throttling on my account on purpose, however we all know they used to do it as they were order by the CRTC to stop doing it. The main area they used to do it was P2P (which XBox Live technically is). I have been a Rogers customer for over 10 years I am wondering if they have forgot to remove something on my account.
My XBox Live speed has never been over 30Mbps (download) for years (used to have a 360) but it was never that much of a concern as I did not have such a great package at that point. Now that I have a fibre package, it is not only the fact that it is not faster, it is now way more unstable and sometimes even unusable.
