why is my new smart hub using 95 mb every few minutes?

[Unfit1]

we just purchased a new smart hub and in 2 days have used almost 3 gigs of data and have watched no movies and only half a dozen 4-5 minute youtube videos...when i checked the usage it shows 95.35 mb being used every 2-3 minutes....is this happening to anyone else?

What devices do you have connected to the hub? There are many applications running in the background of devices that check for mail, updates, new posts, etc. that you may not be aware of. The problem isn't the hub, it's your devices.
