DIscrepancy Between Orbi Traffic Monitor and ISP's Reported Bandwidth Usage
Is anyone else noticing a discrepancy between what the Orbi Traffic Meter reports versus what your ISP (specifically Comcast) is reporting? Before I complain to Comcast I was hoping to see if anyone ...
It does appear to be working as expected with the latest firmware, or close enough within fault tolerance. Monthly, Yesterday, and Today records seem to fall within acceptable expectation.
April:
Orbi - 610GB
ISP - 588GB
Tap - 540GB
I expect the Orbi to have the highest record since it should actively track every bit of data running through it at full line rate.
I expect the Tap to have the lowest record since it it limited to USB 2.0 Bus speed (Raspberry Pi) and therefore will not fully record any traffic exceeding ~300mbit/sec.
I expect the ISP record to sit between the Orbi and Tap as a general guideline due to the previously mentioned reasoning as well as being on an expected slight delay.
The firmware running at the time was V2.2.1.210
I found and executed the manual firmware update process of V2.2.1.210 --> V2.2.1.212 --> V2.3.0.32
After these three firmware updates on both RBR50 and RBS50, the Orbi found and updated to the latest firmware V2.3.1.44
The router is directly and solely connected to my personal owned ARRIS SURFboard SB6190. This modem is the only device connected to coaxial cable at my house.
Orbi Traffic Monitoring has been running for several months and the start cycle is very close to the ISP cutoff. I want to say Comcast switches periods at 10pm EST on the last day of the month while the Orbi meter is set to 12am on 1st day of the month. I believe I read this switchover somewhere, but cannot find corroborating information at this time. The time period still seems close enough to question such a large discrepancy.

Meter accuracy
Keep in mind that the meter is not in real time, there is a lag between a traffic event and when the meter will actually display it. Also, the meter operates on universal time (UT or GMT). This means that the "new month" which will show a meter reset to zero appears in the evening of the last day of the month across the US.
Well never have had great confidents in ISP meter readings.
Has a factory reset been performed then setup from scratch? Something you might want to try on or near the day the ISP sets up a new cycle for you. Then setup TM again and start to track data and see how each one does like after a week of tracking.

I did perform the factory reset upon finishing this latest set of firmware updates. I"m going to continue monitoring through this month, but April will be the best test period given the limited visibility into Comcast's metering.
I've also acquired a network tap to install between modem and router and going to run Wireshark on another device (laptop or Raspberry Pi) for an additional view into bandwidth consumption; hopefully this sheds further light on the situation.
Ok sounds good. Please let us know your findings when you have them collected.
FYI about your ISP modem:
Funny you mention this.... I just so happened to look at mine last night and realzed all historical information was gone. I have not done any reset etc. The only signficant thing done has been firmware update to .44.
Anyone else see those logs get zapped on FW updates?
