Homeowner baffled after washing machine uses 3.6GB of internet data a day

As someone else already posted, the 3GB was incorrect, it was a router reporting incorrect traffic.

But that doesn't seem to stop everyone here from continuing to post how the thing that didn't happen in the first place is ridiculous...

I'm sure this got posted before and the most likely reason was that it was downloading some sort of update and failing to apply it repeatedly.
