Hello,
I installed NetWorx a couple of days ago and after a quick view of my summaries I see that on the 5th and 6th Sept I uploaded 532 TB of data and downloaded 40 TB. I looked at my uTorrent, it shows a couple of hundred of Gb (130 + 40 + etc..) this should add to about 400Gb and I view some online streaming and forums...
I still think this is off... I'm on fibre... but seeing these numbers my modem should be burned by now.
