The usage meter is a bunch of JUNK. It only shows the usage total for the month, It does not show usage for the day, it does not show the URLs that the data comes from. I check my usage last night, Unpluged the router, got up this morning Plugged it back in. I used 3 GB of data last night with the router unplug. How is this possible ?
Comcast will not provede support to answer this questio. They will charge you $10 for every 50 GB over 1TB, But will not provide the infomation to verify the usage.
We have run into a similar issue, with frustrating results.
Our usage spiked ridiculously in September, from ~120-200GB/month to 1300GB. Obviously, something is wrong. When I reached out to customer service, after 46 minutes, two different people just said, "well, streaming videos uses data, so it must be that." But, we haven't changed any of our habits, except that our child went back to school. This means that there are fewer people in the house, so we would expect usage to drop if anything. Not helpful at ALL.
I checked to see which devices are using WiFi, and we recognize everything so far, so I do not feel that our network has been compromised. The website and app show device usage from "zero" to "very high", but no metrics other than that, so narrowing this down to a specific device hasn't been possible.
Yesterday (the 2nd of October), it showed that we had already used 79GB for the month. Last night, I restarted our modem, and today (Oct 3rd), it shows 3GB MTD.
We'll keep a close eye on this going forward, but I do not feel that my concerns were addressed in any actionable way. Disappointing, but not surprising.

If you have xFi with a rented gateway router https://internet.xfinity.com/devices will show individual device usage over time. Not as nicely as you'd like because it is just a low/high graph but you can see which things have high usage.
However, note that there are several threads here with many people seeing unreasonable usage numbers and some are now reporting that October has been reset so perhaps the error has been recognized.
There is no Xfi available on my purchased modem. Xfinity provided no support. I have had a ticket open for 5 days and have not received a return contact.
Xfinity is showing 4 times (400%) the amount of data usage as my asus modem. I have never used more than 400GB in a month.
Last night Oct 3 the meter for the month went from 48 GB to zero.
They are having real problems but not informing people.
