Does your router have the capability of restricting access to authorized MAC addresses?  My usage spiked high until I changed out the comcast modem, turned off xfinity access, and restricted access by MAC address.  I have used 83GB this month down from 300+ ... View more

I used 142GB in December (102GB the first 3 days), 295 in October and 350 in November.  Exchanged the Comcast wireless modem, turned wireless on that off and started using MAC filtering on my wireless router.  Not sure what worked but something did.  ... View more

I had 102GB of data usage the first three days of December.  At that time I exchanged the modem/router.  I also started using MAC filtering on my router and turned off the comcast wireless.  Since then I have used 40GB of data.  I suspect that there was something wrong with the previous comcast equipment. ...

My data usage went back to my normal low usage after I exchanged the modem,  turned off wifi on the Comcast modem and setup tight security on my wireless router.  Went from 102GB in first three days of this month to 1 to 2 GB per day since. @H8Datacaps wrote: @vshoang wrote: Wow! 600GB a month is a lot, but it is going to add up if Comcast counts your data usage 2 times.  That is exactly what I saw them doing after monitoring them for the last 3 weeks. For the old data usage, you should be able to compare the last 3 months if you login to their desktop apps or website.  Though you can't find out much beside looking at those bars comparison.     It's been 600+ every month since I installed the security system.  We only stream one or two movies a month.  My 2 kids do watch YouTube like every kid for an hour or so every day but we use 300 GB in 10 days.  I don't believe that I'm really using all that but despite my hours on the phone Comcast cannot tell me what is using all that data.     I truly wonder how many Comcast customers use less than 300 GB according to their gauges.   ...

I have a modem from Comcast - Make & Model: Arris Interactive, L.L.C. TG862G  Phone and internet with four GB ports and wireless.  I have wireless turned off and only wired connection is to TP-Link GB wireless router.  Settings on router are as secure as I can mkes them.    Tom @vshoang wrote: Hi Tom, Do you mind sharing the type of modem that you have and had.  My modem is Motorola 6121, and the issue is quite interesting because the Data Usage Meter still reported 6GB to 10GB after I power it off at night.  if it is a modem then I am happy to give it a try.  I thank you for sharing the experience with us.  Btw, the data usage meter has not been refreshed since this morning.  I wonder how much they are going to deduct from my cap once it refresh later :)   ...

@vshoang wrote: All, If your router is capable then I suggest  that you enable your router traffic meter to monitor the amount of data that you use.  This will help you to compare the usage against Comcast Data Usage Meter.   Without having your own traffic meter, Comcast can report inaccurate usage due to 1. programing change, 2. data collection process change, 3. wrong data manipulation etc..,   This is evidence in the TN area.  Comcast made a reporting change in the Data Usage Meter, and raised the amount of usage jump from 61GB monthly to 347GB monthly in my case.  How do I know the reporting change?     If you do a 3 months data usage comparison on Comcast website then you will find out September, and October reported in two different categories.  But, there is only ONE category starting in November.   Like many of you already experience.  According to Comcast, my data usage jumped from 44GB in september, 61GB in October, 347GB in November and 130GB in the second week of December.  I even shut the cable modem off at night, and Comcast still shown there were 6GB to 10GB.  I spent a lot of time to research and monitoring my network usage base on the diagram provided by NetForecast aka Independent Auditor for Comcast.  I found out that Comcast reported 2 times the total data of my network usage.   I reported this case to their Quality & security Team yesterday, and they are currently research my case.  In the meantime, I continue to monitor and gather all of the evidence and proof to prepare for the next step.  Please feel free to contact me you experience similar issue, thanks.   Vincent & Vincent Group  I have a similiar problem.  Low usage of 30 to 50GB through September then 295GB in October while I was out of town the first two weeks, 350GB in November while out of town the last 10 days and 102GB the first three days of December.  Did exchange modems after that and usage has dropped to previous low levels.    Tom ...

Late to the discussion but having the same problem in Memphis area.  Over 100 GB in 3 days.  Lots of data while out of town last month.  Have swapped xfinity modem and will see if that helps.  Wireless has new password and is secured to allow only specific MAC addresses.  Other that pulling plug don't know anything else to do. @jckrell wrote: Memphisdata, i'm in the same area as you. Wondering how many others are having this problem in this area?   ... View more
