how much data are you using?&nbsp;
Any recent additions to your network such as a smart tv? device?&nbsp;
You'd be surprised how fast data can be used with a smart tv.&nbsp;
another thing to check is malware/virus/etc.&nbsp;
I've been hit before with a virus that was using data and used almost 600gig in 2 days.&nbsp;
Most windows and android device have a data usage monitor you can check.&nbsp;

Thank you for your response. &nbsp;I was using less than 400 GB a month then in January it began spiking up to 1,407GB in Feb. &nbsp;We do have a smart tv, but do no streaming, downloading movies, etc. &nbsp;No other new devices have been added since last June when we purchased the TV. &nbsp;I do have a ticket in to Xfinity security who will help me change the wifi password tomorrow (I hope! ). &nbsp;Have a great evening.

Try checking on your android and windows devices to see which might be causing it. It could be something malware/virus related.&nbsp;
