I don't have any set top box. Also no xfinity app. I have only one gateway modem. I monitored all MAC address. ... View more

yup...   Even though I physically disconnected the cable (2 days ago), the usage keeps going up. It's ridiculous.  Unless outsider physically hijacked the cable somewhere, there must be issue on xfinity metering or other security comprimising on them. ... View more

I disconnected cable itself from the gateway modem and i didn't use xfinity service for around 21 hours.  xfinity says the usage is 1092GB (at 9/06AM today), so >20GB usage even though I didn't utilize any (1069G at 6/38PM yesterday)   frustrated...                      ... View more

Thanks for the information,   There is no set top box and my netgear gateway c7100v has only connection with cable (isp) without any splitter.  (only me and my wife exist in home, who don't do netflix ever, no youtube recently; also no cloud based backup) What I assume is that no once can hijact from outside unless they physically split the wire, please correct me if I'm wrong.   I even disconnected cable from the gateway and now I don't have internet; I doubt it would help to narrow down the issue though. I will check the usage tomorrow from xfinity my data usage page...   Best Regards, ... View more

Hi,   2.5 days ago, i got notified I used 90% of 1TB. Yesterday, I got notifed 100% of 1TB limit. Since yesterday, I disconnected all wired and wireless device (except one pc for monitoring) and kept monitoring my own router,  NETGEAR C7100V. Since I heard 24 hours windows needed, I compared since yesterday. In my routher it says ~200MB traffic (both upload/download), but xFinity website says additional 30GB since yesterday. I've been talking with xfinity agent/security/techinition on the phone, and they keep saying xfinity does not have any problem on their end, even though I argued there must be something based on the big difference of usage between my router and xfinity side... No suggestion/resolution/help.   I would say goodbye to xfinity unless I get some knowledgeable explanation/suggestion/help. FYI, I'm computer consultant understanding networking/security on computer, and I've been using xfinity with no issue so far.   Could someone have similar issue, or any help on this?   Thanks in advance,     ...
