I have used 13 Gb in less than four days for two Mac desktops. We do not stream, we do not play games; we do not have auto updates; we do not watch shows. We surf for mainly news and do email. I do not understand how we are using more than 3 Gb/day. The six devices are two Mac desktops, 2 iPhones, and 2 wireless printers. I want to know which device is using the bandwidth, and which apps on the device are consuming the information. Can this be done with WireShark?
