Bandwidth Usage

Level 3

Is there any free software to messure bandwidth usage?


The usage that TPG gives me is always 2 days late.


So I purposely didn't use Youtube or look at any videos for 2 days now (during peak but I did look at videos during off peak), but TPG says I used 2 gig! during peak 2 days ago, which is immposible.


So I want to start messuring my usgae using 3rd party software.


Any ideas on free software?
