FWIW, if you have the Gigabit Pro (fiber based / FTTH) 2 gigabit speed tier, there is no data limit. Only the Gigabit (coax based DOCSIS 3.1) 1 gigabit speed tier has the data limit in some areas.

Re: Data Usage

You are still saying that with the loss of 1 son that played xbox and the rest staying the same, ( I always kept track prior to the  1TB kicking in, when things were unlimited, not enforced) we used no more than 640 GB every month. So your math is (640GB- 1 son-1 xbox-1 phone = over 1 TB ) ?????

Re: Data usage

Mine did the same thing! I jumped from 463 to 895 in one month without changing the way we did anything. Now it’s the 3rd day of Dec and I’ve use 66GBs of data. We’re a two person household and no one was home one of the three days so everything was paused!

Xfinity reporting wrong data usage

I was using my own Motorola Surfboard modem connected to a Unifi USG router.  The USG router is connected to a switch and 100% of my traffic goes through the USG.  2 ½ months ago I started running into, and then over, my 1T monthly data usage.  The controller for the USG provides detailed data for my activity and there was no way I was even coming close to my data cap.  By my esitmates I was averaging less than 10gb per day versus the 30-50 per day being reported by Xfinity.  I called to explain something is wrong on their end but kept getting forwarded to an overseas data security group who will only repeat thay there must be a problem on my end.  On one of my many calls I was fortunate to get a representative based in the USA named Josh who pointed out that if I were using the Xfinity XFI modem/router, then Xfinity could identify for themselves which one of my devices was causing the issue.  The XFI modem router is rental only for about $10 per month.  I decided to try it as I could always return the rental.  

 

The results were astounding.  I connected to XFI and kept my downstream setup intact.  Low and behold all of a suddent my data usage being reported to Xfinity went down to below 6gb for the first two days!  It would appear Xfinity is forcing me to rent the XFI device otherwise there is no remedy to the over-reporting of data usage.  This reminds me of what Volswagen did  when it concocted a scheme to have diesel emmissions reduced whenever one of their cars was connected to a state emissions testing system.  

 

For those of you using your own modem with data unexplainably high, you too may need to pay the $10 monthly tax to rent the XFI in order to remedy the problem.

Re: Data Usage Increasing by More Than I'm Actually Using.

Did you replace your modem?  I had the problem with overage and it took a month and half to figure it out.  I replaced my modem, sold the old one.  The old one was still on my account and the new owner was somehow able to use it under my account.  Get Xfinity to check out the mac address of your modem and if there are more than one set up on the account.  Have them delete any that you are not using.

Re: Surpassing data usage limit

I had the same problem after switching modems.  Finally figured it out.  I sold my old modem but it was still on my account and I got charged for it's usage.  Have them check how many modems are on your account.  Verify the MAC address.  Delete any old ones.

Re: Surpassing data usage limit

I would have them delete out your current modem and add it again.  I never thought my modem was still on the account until we reviewed the MAC addresses.  My usage was going up about 2gb per hour.  Usage stopped after they deleted my old modem.   I just hope it does not start up again.

Monthly data usage has increased by 1000% (ten times) and I am being threatened with overage charges

I have an unlimited data plan with Comcast. Usage historically has been about 200GB/month. In November it went up to 2075GB and in the first 2 days of December it is almost 300GB. (all passwords were changed in mid November and we were away for the last week. ) Nothing has changed - no new apps/streaming services, etc.

 

I talked with Customer Service and they could not help. A tech came out in mid November and had no suggestions. So I am using about 150GB/day. I spend about 1 hr/day doing emails, reading news , etc.  

 

Any ideas how to sort this mess out?? Thanks

Re: Data usage

There's a long discussion thread over here where people have described various culprits they've discovered and how to deal with them. 

 

The most common things we've found are:

 

  1. Online backup services (Carbonite, Backblaze, Amazon Web Services, One Drive, Google Drive)
  2. Malware (rogue software installs, viruses and trojans, hacking tools, browser addons, cryptomining)
  3. Torrenting (BIttorrent and related apps)
  4. Online video streaming and uploading (Netflix, Amazon Prime, Hulu, YouTube, Xfinity Stream)
  5. Game consoles (XBox Live, Twitch)
  6. X1 Cable Box streaming (any internet app on the X1 platform counts)

Since nobody has exactly the same hardware and network configuration, people are just going to have to monitor their usage and troubleshoot individually. 

 

Some good tools to have:

 

  1. Network Traffic monitoring apps such as Wireshark and GlassWire.
  2. Xfinity xFi
  3. Individual router bandwidth monitoring applications if you have a personal router.
  4. For Windows 10 users, the OS has built in Usage Monitoring and Metering. 
  5. Malware scanning tools like Norton Secuity Online, which is free to Comcast customers.
  6. Remove any browser extensions you don't use, and keep a close eye on those you do. 
  7. Update your software regularly.

Re: Data usage

Been there. Done that. (And no tee shirt)

No set top box apps used. Backups throttled

Point is router sees all traffic and categorizes it by DPI. I know exactly how much data I use streaming and backup and social media. And the total is 1/2 to 1/5 what Comcast reports.

But Comcast refuses to investigate unless you pay for their xfi modem. Only other solution is to pay for unlimited data. Bottom line is “pay more”

Re: Data usage

WaldoMI:  I saw where you said you have a UniFi network from Ubiquiti.

 

I searched for: ubiquiti router traffic meter vs comcast

 

… and found a thread on dslreports where a guy's Ubiquiti router is reporting much less data than Xfinity.  Eventually he installs a different monitoring app and reports: "Just checked SNMP logging and it seems to be agreeing with Xfinity. So DPI is just broken." And another person responds: "DPI has been reported to on/off broken in various ways for years. Some firmware releases reportedly improved the accuracy, as did turning off smart queues, and rebuilding the database (to remove corruption)."

One possible solution from the UniFi forums is to turn of regular "speed tests" that UniFi controller performs.  Im trying that now and will check back in a few days to see if it solves the disparity in data total reporting.

Re: Data usage

The "speed test" solutions seems to have worked - in the last two days, my router reports 10.9 GB of data used and xfinity reports 12 GB of data used.  This is much much closer than the 2x-5x differences I saw before turning off the regular (every 30 minute) speed test in the UniFi router.

 

Thanks to everyone on the fourm for their suggestions and support.  Hopefully the rest of December will turn out to be uneventful.

Xfinity data usage meter inaccurate

I was Xfinity Customer Since i was in the school. I opened a new account since April 2017. The average data usage is about 300Gb every month which is totally OK. But somehow since Aug 2018. The data usage is abnormal. Per their records. I used over 1TB monthly. Obviously  Xfinity data usage meter inaccurate. In these markets, users that cross the 1 terabyte limit face overage fees of $10 per each additional 50 GB consumed.

 

I am not sure how they collect my data usage information, i did some testing when no one at home. Dec 1 2018. (see below). No one at home until 7PM. I streamed 2 hour youtube and then i check the data meter, wow, can you believe i used 18GB data for 2 hours youtube. Do not tell me this is true.  I tried to call billing department to waive the penalty, they said this is policy to charge me.  I called technician to solve this issue. However, there are nothing they can do.  

 

OK. Well. I am done.  Let me just switch to ATT. $40.00 included Equipment. IT IS JUST SO HARD TO BE A LOYAL CUSTOMER.

If not service issues, then billing issues used up so many hours of my time every month on the phone, I considered invoicing them for schooling their reps. AT&T PTSD seems conditional to their terms of service. Comcast calls to inquire about their quality of service to me run a ratio of 4-to-1 to my contacting them over the last couple of years. As one among many N. Cali Camp Fire evacuee survivors, Comcast continues to bend over backwards to ensure they come through no matter where or what our circumstances are. All my AT&T serviced comrads are linking up with Comcast's free fire disaster hotspots because a month into our recovery, AT&T's services are still down.

Extreme increase in data usage

I've exceeded my 1024GB data cap one month, quite a while ago, but it was a month of pretty heavy gaming and streaming. Usually I'm around 600-850GB usage. Which still seems high. I started this month out in the first 10 days at around 285gb. Now 3 days later I'm at 356gb. I keep reading on the Xfinity site how much you would have to do to get close to the data cap, but I seem to boost my usage really quickly. Is there something happening that I may not be aware of?  Me personally, I don't typically don't stream or game online that would use data. My son games online and watches Netflix, and my wife watches Netflix.  The past few nights she went from using Netflix through the X1 platform to just watching it through the TV (glitching issues).  She has only been watching about 3 hours of Netflix, and my son doesn't come home until 3PM. How in the world can we be using this kind of data in such a short period of time? 10 hours possibly of Netflix/gaming total and in 3 days used around 70GB.  And nothing is being downloaded, just streamed.

Frequent Visitor

Re: Extreme increase in data usage

Just wanted to add I do have the Xfi app, but all that does is tells me who is using the majority of the data. It is my son, but that would make sense because he typically spends more time on it as he gets home and jumps online.

Frequent Visitor

Re: Extreme increase in data usage

Another thing I just noticed. On my data usage page under the modem it says 307GB used, and yet under the amount used for the month it says 357GB (somehow went up 1gb since I just checked an hour ago), but why is there a discrepancy in these numbers?

Re: Extreme increase in data usage

The X1 box has its own modem/router that is used for apps like netflix.

 

As for ways to use data - there are really quite a few.  See the terrabyte usage thread for ideas. (This thread will probably be merged into that one.)  Some examples are Amazon Drive, Backblaze, BitTorrent, malware, various programs with bugs, etc.

One of us do [my set up's too out-dated or I would too]. You-Tube tends to skitter and drop, maybe due to low-end plan [internet essentials]. Or maybe something to do with the 5 extra "on-demand" hotspot riders discovered on my gateway's connected devices list while trying to figure out why internet performance all at once started degrading. DSLreports.com steered me to an interface page giving Xfinity customers option to enable/disable the hotspot feature. I just learned it only gives appearances of offering a consumer choice and short of a sledgehammer, the hotspot feature is always on no matter what you do.

"...short of a sledgehammer, the hotspot feature is always on no matter what you do."

 

Correction - the person telling me the enable/disable interface settings do nothing to disable the hotspot just clarified that it only applies to Comcast's security services which are "always on". The person advised that the interface settings DO work to disable the public hotspot feature on Xfinity-branded gateways, and can be found here:

https://customer.xfinity.com/#/settings/security/hotspot

I set it to disable last night and thus far, still have "on-demand" hotspot customers listed as connected devices through my gateway. Takes 24 hours to have effect, so it says.

Re: Extreme increase in data usage

I have had the same problem, a sudden jump in data usage that put us over a terabyte the past 2 months. There are only 2 of us here, my husband has an xbox but he rarely uses it, the television is off all day until the evening. I've had a tech out that says there's no way we are using that much data, I've called and followed all suggestions except to download the xfi app because I have my own modem. I was told our problem was "escalated" but there's been no call backs, no emails, no anything and my data usage just keeps going up. Comcast doesn't actually seem to care, they will just charge us for data we aren't actually using until I finally give up and go to AT&T. I'm almost to that point.

Re: Extreme increase in data usage

Many non-Comcast routers have traffic monitoring and analysis of their own (to varying levels of detail.)

 

Check the terabyte usage thread for more tracking ideas.

 

Recently, someone in that thread found that it was his owned router itself that was consuming lots of data.  It had a feature to automatically do speed tests, so he turned that off and that seemed to fix it.

Re: Extreme increase in data usage

Yeah, I had a chat last Thursday and was told the same thing, but no emails, no call. I'm using the Comcast provided Gateway that also costs $11 a month to rent. This is ridiculous that suddenly I'm using 3x more data than normal and no explanation. The day I used 70GB it was no more than 10 hours of streaming netflix. And not in 4K.  No video gaming or downloading video games.  I personally don't play much online (my son does), but whenever I decide to, then I see a huge spike in usage too, so I monitor it nearly every day to make sure I don't go over. This month there's no excuse for why it is so high.  For some reason, it actually used much less this weekend, even though we've spent 15 hours or or more per day streaming and actually playing video games. Again no explanation as to why we would have used less these last couple of days even though our time online went up.

Internet overages

I am suddenly  going over my 1 TB data plan.

 

I’ve done nothing different the last few months, but two of the last three months I’ve either approached or gone over my 1 TB  plan.

 

Can someone explain to me, when I’m doing absolutely nothing different,  why am getting close or going over my 1 TB plan with Xfinity? This seems like a rip off. It seems like a scam.

Data usage looks off...

I track my data usage on my router, yes I am tracking both uploaded and downloaded data.  Over the past 3 days I am showing 23gb of data over my router, but when I look at my data usage on the Xfinity site, it shows almost 90gb of usage for those same days.

 

I've read too many horror stories about Comcast and data usage disputes so I am trying to get in front of this as it is the 8th and I am at 300gb, which seems...very questionable to me.

 

I run a secure home network and work in network security so no one is leaching my bandwith and I have tight control on what uses my network and how.

Re: Data usage looks off...

Check the terabyte usage thread for known ways to consume more data than you think you are.  Ways include not accounting for cable boxes, routers with built-in scheduled speed tests, and relying on router metering that is already known to be inaccurate.

Data Usage Soaring

Suddenly my data usage is soaring.  I've averaged about 300 GB/month previously but suddenly am consuming 100 GB/day!  I changed my router name and password, rebooted the router, turned off my cameras, disconnected my Internet-connected switches but still the data usage continues. There are only two people using this account and we watch an average of an hour or so of streaming video.

 

 

But, actually, our Internet behavior hasn't changed over time. I see other complaints but no real solutions.

 

I've called support who couldn't help. They referred me to CSA Data Escalation who provided absolutely no assistance. I don't know where else to turn except to simply leave Xfinity for another ISP.

Re: Data Usage Soaring

It sounds like you may have some errant software running that i consuming bandwidth,

 

First, do a full scan with your AV program to make sure your system is clean.

 

Then check running processes that consume bandwidth via the Task Manager.

Re: X1 Data Usage

My XFi app was telling me our "household" profile was using 80% of our internet data (and we go over the cap every month so that's a lot of data). At first I thought someone was piggybacking but higher security and password changes didn't alter it. I finally unplugged the wireless X1 box (even though it had been turned off and no one had used it for days because it's always been frustratingly glitchy) and the high usage stopped. Everything I saw on the internet claimed the box doesn't count against our data unless we're watching an app like Netflix, but if I unplug it the high usage device disappears, if I plug it back in the device data skyrockets even if we don't turn the box on. I assigned the device hogging all the data it's own profile and paused it and that makes the box stop working so I know the device using up so much data is the wireless X1 box. I've left it unplugged for weeks and the data stays down, then plugged it back in (but didn't use it) and had the profile start using all the data again.
