we have a mixture of machines which consume internet, the hungriest of them runs Linux Mint most of the time. The others run various strains of Windies and a couple of phones run Android. I guess one solution won't fit all. Our ISP is Sky, which we just got dropped on when o2 got out of the ISP business, they have just sent us a new WiFi/modem/router. Possibly it or they can supply the usage info. I'll check when I get it connected.
Thanks for the input,
