Does anyone know of a free bandwidth moniter that is easy to use? I just want to put it on one computer connected to a router, that shows overall bandwidth usage by each computer connected to the network. I'd like something like this http://traffic-counter.digitbyte-studio.qarchive.org/ but you gotta pay for that and I'm not sure whether it will work for networks. Mainly I want to use it so I will know whether I have gone over my download allowance. Apparently 3 computers in my house are using over the 40gb cap. Oh and also what sort of internet activities aside from actual downloading uses up the most bandwidth?
