Measuring Data on Router
My router reports Tx Data Packets and Rx Data Packets for my WAN port and it has a standard setting of 1500 for the MTU.
So, if I keep a running total of these packets I can then multiply by 1500 to get the maximum value of the data that has been handled on the WAN port.
That should be the same or close to the data usage recorded by Xfinity.
Am I correct?
