> But the bandwidth used recorded by it doesn't seem too precise
How do you come to this conclusion? If there is somebody that should know how much was pushed though, it's the router...
> limited bandwidth (125 GB)
Limited datacap, or just a datacap of 125 Gb/month :)
> 4-5 GB per day which I am sure I'm not consuming
I tethered for about 2 hours and saw 1 youtube video and a few imgur pics and was at 600 mb for the day, 4-5 Gb a day doesn't seem that improbable, especially.
The disparity is kinda strange, and getting 3rd party program might settle who is wrong.
Not sure if this will work for you, but check for free monitoring tools so you can monitor directly on the machines. It is more of a pain in the ass, but it allows you to doublecheck the figures.
If you're using a Mac and your router supports SNMP, have a look at this app:
Provides real-time monitoring if your router's connection in the menubar. Really handy for measuring your ISPs performance or for seeing how much your Internet is really being used.
...later...
If you run a Mac (I do!) you can use a great piece of software called PeakHour 3, which connects directly to the router and gives you a nice graph of incoming and outgoing bandwidth, as well as keeping a logfile. I'm hoping to use this to see gaps in the outgoing bandwidth, which is what I'm expecting. That'll be helpful, I think. It's free for the first week, and then it's something like $5.
Thanks also to the mystery Telstra guy, contacted me via a DM and confirmed that my actual connection looks good.
I see, I'll look into that. http://peakhourapp.com
Do you think this app will let me monitor not just my Mac laptop but with all my other devices connected to 1 router?.
EDIT: Looks like it can monitor multiple devices, will try the trial first.
Maybe not relevant, but if you are on a mac and are using snmp I would suggest http://peakhourapp.com/ then you can see the traffic live (1sec int) from several snmp targets.
