Oh! That must have been it, thank you. I'm not very familiar, I just knew the cables were cat6 and cat5. Thought it might have something to do with the shielding.

Looking over the product page, it's marked as S/FTP

Yeah don’t use grounded cables if you don’t have ground to actually ground them.

Correct. More specifically, if a shield is not actually grounded, all it becomes is a re-radiating antenna for all of the EMI around it, as well as a means by which to directly transfer electrical noise from one device to another.
