Unusually high data usage megathread

OK...I have read ALL the complaints about data usage.  This is an Xfinity site!  Outrageous!  They have still not answered all this outrage.  Simple.  My wife and I are retired.  We are NOT computer people, gamers, or big smartphone users.  6 Devices in our house.  We followed all the guidelines for usage when we cut the cord last August.  I set up a spread sheet and monitor daily.  We go over a TB every Month!  Two OLD PEOPLE!!!  

After calls and calls I was finally told to go on their app that gives me usage by device.  The numbers aere simply wrong.  We have to believ their numbers or go away.  Yes, I believ it is a scam and so many times I have been tempted to do the %0.00 extra and go away.  It really isn't about the money.  It is SO typical of the Canle Industry mentality since their inception.  "MUST increase usage by customer to increase profits".  I will get out f this some how, even if I have to drink more often. LOL...However it isn't really funny...the cable and internet compaines are indeed out to get us.  I guess we are all in on the conspiracy.  I do know one thing...changing to internet only and cutting the cable has only made me HATE COMCAST more!

My internet usage for December 2019 shot up from 800GB on 12/26 evening to 1.6TB on 12/27 morning, and got a call from Comcast automated system that I have exceeded my limit. My Internet usage has not changed. This is the third month where my usage has hit close to 1TB and I am seriously considering alternate options. Comcast does not have a clear answer on why this is.

My usage has been the same and hovering around 600-800GB / month. Why will my usage double in 24 hours?

I have been using almost no internt the last four days and am still getting charged for 5-7 GB of data per day.  In fact, I even unplugged the moden entirely yesterday for about 24 hours and just now plugged back in and it says I used 9 GB of data in that time.  Basically 200-250 GB of the 1024 GB I am almost maxing out every month is being stolen by Comcast.  Don't expect that you'll get ananswer from them, they know they can stay hidden like cowards and keep lying to people and stealing from behind the internet... because they think lying and stealing is what the people paying for the internet are doing.  There's nothing you can do about it because they're hiding behind the internet and remaining anonymous and the only way to get at them is through the internet anonymously.  

Vando22,

I think you got your test almost right, except for the fact that Xfinity says their meter may not include data used in the last 24 hours.  So, you don’t know if that 9GB really happened while the modem was off or sometime in the previous 24 hours when it was on. 

So, to improve the test, try it like this: Turn off the modem for at least 24 hours.  Check usage (preferably via another method such as a phone so you can keep the modem off the whole time.) Use this as the baseline number and leave the modem off for at least another 24 hours. Now check again. If data went up on the second 24+ hour period, then something is going on. 

I've been using unlimited internet for over 20 years, since 14.4k dialup modems.  Recently, Xfinity lobbied to have Net Neutrality killed.  Now there are data caps!  By having a data cap of 1024gb, Xfinity has crippled my ability to utilize media sources that are not their own.  I can watch unlimited cable TV with Comcast, but I can't watch unlimited Sling or Netflix.  In casual use, my household reaches this 1TB data cap every month.  Additional service of "unlimited" internet now means more than DOUBLING my internet cost!  If I want to use a media source that's not Comcast for the same duration each month, such as Hulu or YouTube, I'm forced to pay up, which I can't afford.  The President cannot legally block me on Twitter.  And yet, an internet provider can now block me and force me to pay fees for the data of viewing that same information if I've already met a restrictive data cap.  This is shameful.  Comcast / Xfinity is the worst company I've ever known.  I'll be glad to be rid of them forever.

Have never approached the level, hit it 2 months ago, scanned my computer, found 2 suspicious items, no big deal but maybe that caused it.     Hit it again last month, now my 2 give me months are up.   Now here we go again.   Come on xfinity, there is a problem here.    There is 2 people in the house and we use the net in the evenings but that is it.    Something is up.

My monthly data of Internet usage has never been above one terabyte per month prior to Sep 2019, and the monthly average for June, July and Augusts was 842 MB, but all of sudden the monthly usage of data for Sep, Oct, Nov, and Dec (still two more days to go) skyrocketed to more  than 1.20 terabyte (an increase of more than 40%). We have been using the same number of electronic devices all year long and used Internet the same way we used before. Nothing has changed, except that Comcast decided to raise the bar from their end. It seems that the loyal customers of Comcast are forced to pay monthly bonuses to Comcast ten times a year and consequently do what Comcast wants them to do; buy unlimited data for an additional $50 a month. This policy will leave me no other option but to leave this company and try AT&T.

Our Data usage this month about 91GB remaining of 1024GB,  Some of it legimate usage of PC updates,  Clean install of my Desktop due to getting newer hardware at Christmas, 

Antivirus scans ran, nothing found  (1 PC running Avast Free Antivirus/Malwarebytes 4.0 Free, and 2 Most used PC's running Windows Defender, and Malwarebytes Free--Willing to make changes there if need be) 

Usage is normally a little Youtube here and there,  internet browsing,  Some Amazon Prime video not much, very little Netflix,  even still approaching going over the cap once again

Did check our Gateway Modem Arris TG1682G, even reset the wifi password eariler in the month

Your system is still giving us alerts about us being over a terabyte of bandwidth despite me signing up for the $50 surcharge to get the internet package I paid for so long ago.

Fix your service, and stop harassing us.

Glad i found this thread and i am not the only one. In last 12 months i was over 1 tb limit 2 times. usually around 900GB or below. Today i faced a really weird thing. My billing cycle is from Dec 1st to Dec 31st. Till Dec 19th i think i used around 700GB of data. From 20th morning to 30th morning our family is out of town for vacatio. Today after returning from the trip i casually checked my account and i see i have used something around 730 GB out of 1024 GB limit. So i thought i should be good as there are only 2 days in my billing cycle and almost 300 GB of data cap left to use and by my usual usage i will be using 60 GB in the next 2 days. 7 hours later i am over my monthly cap limit by 77GB. So that means i used almost 377GB of data in 7 hours. I am out of words. Today the things we did is probably 2-3 hours of Netflix and 2 hours of browsing in my desktop and 8 hours of VPN connection to my work which hardly takes may be 500-600 MB in those 8 hours. i didn't even downloaded any netflix movies for offline watching or any other games from my xbox store. after i got the 90% usage alert email from xfinity i contacted the customer service and they told me to chage the password for my wifi and install anti-virus on my devices and told me to contact them once i am over the 1024GB datacap limit so that they investigate the spike in data usage. i don't understand why should i wait till i get over my data cap to report it so that comcast can investigate it. And one more thing is comcast says the data usage may not include the last 24 hours usage data. But i saw my data usage chage in the online account 3 times today : afternoon i saw some 279 GB left in my cap, 5 hours later 77 GB left, another hour later 11GB left, couple of hours later i am over the data cap by 77GB. This clearly seems very very unusual.
