Excessive uploads gobbling your data allowance?

If your uploads are higher than your downloads, some things to check are

  • You need to isolate what device is uploading all the data. Turn off all devices and only turn one on for 2 hours and monitor your data usage. Keep doing that until you find the culprit.
  • Login into your account with your service provider and see if you can pinpoint when the uploads are happening. Your RSP will only have hourly data keep for the last 24 hours.
  • Do you have a Network Attached Storage device? If so, turn it off and see what happens. The software on them can phone home for updates.
  • Your router may have been ‘hacked’. Try bypassing the router and plugging your computer directly into the NTD and see what happens.
  • Your computer maybe ‘talking to friends’ in the background. Here is how you can turn that option off.

Apple: Most often BitTorrent, iCloud, Dropbox, or some other cloud-data application is involved in cases of mysterious bandwidth use by a Mac. If you use iCloud, uncheck at least iCloud Drive in its preference pane and see whether there’s any change. If you use third-party network backup or file-sync software, disable that. If you use a torrent client, remove it. https://discussions.apple.com/thread/7314385?start=0&tstart=0

If you have tried all the above suggestions, and still can’t control the uploading of data you will need to contact your service provider and ask for help. They will be able to monitor in real time what is happening over your connection (best done when the uploading is actually happening)
