@Jeff74 -- is your computer running something like BitTorrent? Higher the bandwidth package, the more that B.T. will use.
Is there more than one computer/device on your private network? iPhone? Teenagers gaming full-time during the school-break?
Hello Grand Master mdk. No BT, generally only download updates on my mobile devices, and zero teenage gamers. I game, but not online/multiplayer. When I was on lesser plans and I wasn't in school, I was gaming online and my usage never went over 150-200 GB's. I was also downloading movies and music on the regular. I had 500 GB's used in October, when I wasn't downloading/uploading anything of consequence.The only thing I do now is stream YouTube and the occasional Zoom meeting. Not a huge deal at the moment b/c I'm on an unlimited plan, but a curious anomaly non-the-less.
Thanks for your response. Happy Holidays 🙂
