Tracking of Internet usage

[sunnyblueskies]

Hi again,

Router/Modem: MBR1210 on Bell Mobility, Windows 7.

Question: We have about 7 different devices on our 'Home network', the MBR1210 serves right now as internet access point and router for our home network.
It has built in tracking software that I can enable, but I would like to track each device separately from each other. Is there a way that I can do that on the modem/router? Or would I have to get a third party program. Can anybody suggest a good program? Freeware preferred.

Thanks.
