@antuf , We checked your signal and the values are fine. Did you have a switch or router in between? If so, remove all your own devices and run a speed test by connecting your computer directly to the Connect Box using a LAN cable.
I have no router connected in between but I tried what you suggested and have the same results. Meanwhile your support group sent me a new router but there a still no changes.
I luckily got someone from support today and after doing all his checks he agreed that there is something very wrong so he has turned this matter over to the experts who should contact me sometime. I hope to get it solved soon because it's getting annoying.
@antuf , can you please follow this instruction? https://www.technology.pitt.edu/help-desk/how-to-documents/pittnetwired-configuring-windows-10-wired...
