Why is my computer sucking up all my bandwidth? I have a 10GB cap per month and that costs about 80$. 20Mb per hour is 480Mb per day, which means after 3 weeks my cap of 10GB is used up idling. Some say "This is normal man, this is 2013 get with the times of the sophisticated internet". I don't think 15GB a month idling is normal. The proof of that is I closely monitor my usage through the "Show estimated data usage" in Windows 8 which has always been pin point accurate for me. I also double check with my Bell account to make sure. The point is up until I updated to windows 8.1 or so is when I noticed the massive spike, I thought maybe something in Windows 8.1 was more intensive than Windows 8. Pre Windows 8.1 I was idling at 1-2Mb per hour. If I was playing World of Warcraft and idling on Facebook in the background I was maybe running 15-20Mb per hour. Now with that same combination it's more like 60-70Mb per hour. It's almost as though everything is more intensified by how much data is sucked up by any activity I do. Things to note, I've formatted, I've gone back to Windows 8...somehow the issue still persisted so I went back to Windows 8.1, exact same thing. 20Mb per hour. I've shut off live tiles, I've pretty much uninstalled all the apps. I've looked through the task manager, processes running, app history ect ect. Nothing showing that my data was being sucked up by anything. I even went to the wi-fi section under performance in there and it shows everything is a big fat 0% for network usage. 0.00Mbps, yet when I mouse over the network name at the bottom right of the screen that number quickly enough adds up. Any thoughts would be well appreciated. I haven't found anyone who can figure this out, I mean it can't be a virus or malware because I had the same issue when I've formatted. The only other thing I've done lately that's different over the past 3 years I've been on this turbo hub for internet is I recently switched from a private IP to a public IP address so that my Nat type would be 2 and not 3 for my PlayStation 3 and for Call of Duty on the PC. Somehow I doubt that's the cause but at this point I'm willing to believe anything.
