Roku or Amazon Fire....

Also look into what streaming quality you have your services set at. If a new device changes it because it has higher capacity or it got changed some other way, that’s your likely culprit. But if you are looking at a usage report and you see a particular device hogging, then you can just turn that internal IP address off in your router and you will find out pretty quickly what that device was.

I'm pretty sure the hog is the Firestick. I back tracked my usage to the day I installed it....up until then I averaged less than 10G per day, starting the day I installed it, I haven't been below 16G in a 24 hour period. I changed my video resolution in the FireStick from Auto to 1080, I'll check that for a few days and see if there is a difference. I'm also going to do some other things like spend an entire 24 hour period without using the FireStick and compare all of the data.
