mine is garbage atm, something like 45Mbps downstream and 11 upstream with ~20ms ping (the crappy router IS bottlenecking it a bit, roommate confirmed that router before this one was at least giving 60Mbps downstream which is still garbage)
to some extent it's the ISP being a shitter, but I've confirmed with multiple sources that the wiring in this building is also fairly shit - no word yet on whether the property owner is willing to run newer wiring, or to allow the fiber ISP to run new lines through the building or anything but I know for a fact that my ISP has decreased my speeds over time while steadily increasing monthly cost (and that's not even getting into all the other shit they've tried to pull)
