Like compare your router's bandwidth monitoring numbers vs what your ISP (Bell/Rogers etc.) says you're actually using? Do they compare?

I use a WRT54GL with Tomato firmware, and it does not seem to compare. Just curious if anyone else noticed the same thing. Maybe its just my setup is incorrect.

If you search this forum for "tomato router" or similar terms you'll find plenty of previous threads on the topic. The only time there was a major error that I recall was when there was a "customer number" mix-up (two customers were getting each other's bills for example).

If any of the majors had errors in their usage, it'd be all over the news and this forum. Usually pretty easy to test by not using the router for a day (unplug) and seeing what the numbers are for that day - they should be zero for you and for the ISP. I occasionally check my Rogers daily usage and it always makes sense.

A good time to check daily usage is if you're away for a few days, on vacation, etc. Then come back to see what's there. Or if you've had a particularly busy day or two and can see the "spike" on both the ISP and your router.

Mine's always off by a little bit.
I've always chocked it up to
1) units BS (1024 vs 1000)
and
2) +/- a few hours capturing the value.
e.g. they may not cut off at exactly 0000, it might be +/- a few hours.
So traffic from the overnight that your router is attributing to one month or the other may not fully reflect the usage.

If that doesn't add up, something's fishy. Unless your router isn't the first point of entry (but why would you have it as a meter if that's the case? :p)

My Dlink router is too old so I have to use DU Meter and compare it with Shaw. So far Shaw's been pretty accurate.

Here is my analysis comparing Bell with the stats from my router running Tomato. Not sure if the router and Bell think the day ends at 11:59PM or if Bell is using GMT or some other time zone.

Pretty similar until about mid way through my billing cycle, then it seems that Bell got a little screwed up. In the end, Bell reported 6GB less usage than my router for the month. On day there was an overstatement than correction the next day which seemed strange.

Thanks, Larry. Great chart.

I think I know what I'm doing wrong. I changed my current save history from Ram (temporary) to CIFS storage. I created a folder for collecting CIFS logs, and set my Bandwidth monitoring to save it in the CIFS location. I'll check it over the next few days to see what the data gives me.
