My internet has recently been going VERY slow, so I called my ISP. They said that we have over-used our 60GB monthly allotted data plan, and have used 160GB that month. I would really like to know WHAT has used up all my allotted memory for the month. My Wi-Fi network is password protected. I have NEVER gone over before, so when my average jumps from about 40GB to 160GB it concerns me. I would like to know how I can see what has used up all of my monthly bandwidth, as well as what device (and who) has used it all. In our house we have an iMac, a few windows XP computers, as well as 5 iPhones/iPod touch's. Could 1 iPod touch do all of that, or would it have to be some application on my mac that is somehow running overnight? Sorry if I confused you, and please correct me if I am using the wrong terms. Any help is appreciated.
