Sudden huge increase in internet data usage

Past 2 months I’ve noticed increase usage of data on my internet. I have read all comments regarding this issue . I have lower speed internet and no Cable with xfinity .  Nothing changed in the house in terms of usage of internet . I feel xfinity is targeting the customer that doesn’t have unlimited data and no cable with them . It’s pretty sad that this company is playing this game durning a pandemic. 

Just had the same problem!  Xfinity claims we used our entire data plan in 3 days.  Insane!  The person on the phone says it is just the way it is.  Time to switch providers.

In the last month (December) Xfinity has noted a significant increase in data usage that I believe is incorrect. I've been a customer for 10 yrs, and never had hit my data limit or been even close.

I don't live stream or play games, and there's been no change of behavior that would explain the massive increase in data usage.

Additionally, I was out of town over the holidays, but somehow Xfinity computed 150GB used when the home was absolutely empty. This has to be an error. 

Please help.

I have never come close to the 1.2 terabyte cap before 

What is going on? My new contract increased my download has increased 

my monthly garage if data by 50% .

How can I fix this probkem?  Can a setting change fix it.

In dec, my cost was increased by 1/3 and my de facto data available decreased 25%

Fix the problem ..or tell me how to fix it. 

Your monthly over charges are excessive ..$10 plus tax every 50 mg ...

I usually use less than 800 mg per month ...

Hi,

In about three hours overnight xFinity said we used over 1.5TB of wi-fi data. The data usage detail statistics on the offending computer for the last 30 days only add up to about 140GB.

I received a 90% message on 1/3/22 2:31am (CDT) and a 100% message at 3:31am.

Can you give me any more detail on what happened? Thanks.

I thought I'd  update my situation. It  says my monthly limit  is 1229 gb. Apparently  for Dec. I  used 1228 gb, which is an unbelievable number compared to my  usual  500 or so, and also super suspicious? It seemed to be on an upward trajectory towards the sky when I made my post, and then....slowed  down considerably. So far on morning of Jan 4 I'm at 65 gb, which sounds about right. Maybe they're paying attention to this thread? I don't  know what's going on, but  I'm going to keep an  eye on  it. 

Since November I have been double my normal usage. I have worked from home for 2 years and NEVER had this issue. I cannot find any source as our technology has not changed. There has to be something wrong with Xfinity but the tools provided to look at the devices does NOT allow you to see what is using the most data. You also cannot speak to a human ever so I am almost to the point where I can cancel service online and go elsewhere. Anyone else have this issue with a Comcast router at home?

I am in the same boat as of December.  Rarely hit 500 per month and now in Dec hit almost 2,000 and 4 days into January already matching my average month with my devices disconnected.  I have spoken to tech support twice and sales once.  Been a customer for over 20 years.  Fortunately I have att fiber as an option with unlimited data.  I will not be scammed to pay extra money for data I am not using.  What a poor business model and I hope they lose a large portion of their customer base over their lack of awareness or ability to address the issue from their end. So much for customer loyalty and honest support.

So I've had two calls from Xfinity regarding the data usage.  I did everything one rep suggested except to disconnect everything for 48 hours because I know that too will be futile as I disconnect everything for 2 hours and the meter still went up.  We do not have a smart home, no mysterious devices, no gaming, nothing to support already using 222 gb as of this morning (January 1-5).  So from 200 or less for all prior monthly usage before October's rising increase.  The rep that called yesterday stated that Xfinity does not believe what the customer's are saying.  We have to come together and get this resolved since it is clear Xfinity is not about to solve this problem which is not a new one.  

I have been having the same data issues as well as EVERYONE else! I too am a 20+ year subscriber to Xfinity and have never used that much data before. I spent hours on the phone as well with no REAL answers other than, "I'm just using more". I am in the area that got the "extension" until 2022 on the overage charge and have been trying to upgrade to unlimited data for the $30 that they state is the rate. The strange thing is that it is "temporarily unavailable". Why is that?? It is now January 2022 and my area will now be subject to the overage charge. According to their fabricated data usage number for me I would have to pay close to, if not the "max" charge of $100 EXTRA per month! So of course, it's "temporarily unavailable" to me, that way thy get an extra $70 per month from me instead of $30! This is a scam and with this many complaints about the same issue I do not understand why Xfinity has not been investigated. I am now going to start the process of finding a new provider and also find out why they are able to do this to their customers.

I am ready to switch companies if this continues. I haven't gone over the 1229 gig limit yet but this month (January) I could go over the limit. There have been so many comments from so many people but no answers yet. I have Ziply fiber in my area. I could switch for 200 mpbs for $40. I will wait awhile. Keep complaining.

Haven't seen anything definite, but Xfinity must have identified a major, major bug in their system to track internet usage. They also may have corrected their problem, but I am keeping tabs on a daily basis.

Background: During the last week of December 2021, I received a warning that my usage was close to 1 TB with only 229 GB remaining in my monthly allotment. This is many, many times over my normal monthly usage, over the most recent 6 months. I also received the standard "offer" to go to unlimited internet for an additional $11 per month. I declined and finished December at just over 1 TB usage. I know something was wrong and began monitoring our phone and other device usage.

Well, I just went in to check the usage site and lo and behold, my TOTAL usage for December is now reading 102 GB....  uh???? I'm glad to see usage cut by a factor of 10, but this sounds like it was an Xfinity workaround. I hope Xfinity has actually found and corrected their bug. In any case, if anyone does get billed for overusage (or notified they exceeded and received the "free" one time pass), challenge Xfinity and insist that they fix what is clearly their own problem.

I showed about 90gb of monthly usage as of this morning. By end of day I am showing 410gb used. No way I used 320gb all by myself in one day. I am growing tired of this [Edited: "Language"].

Im Having the same issue, did you get this resolved?  I'm having a hard time reading this thread.  Thanks for your help.
