Usage depleted overnight. All updates set during free time.

Lea if you insist on leaving the router hooked up at least clear the traffic monitor and write down what time you did this and clear Glasswire and then take a scree shot of the status meter then in 24 hours take a screen shot of the status meter, traffic monitor and glasswire and post the screen shots here and we maybe able to see whats doing it. I would also change the password for the wireless in the router just to make sure no one else is using it.
