I have attached a file that contains my monthly usage since Jan. I can only get the detailed daily usage for the time since the last bill. As you can see in the attached file that my problem started last month actually about 10 days from the end of last month. Having not resolved the problem nor really being able to see how much data I was using I was pretty much turning my computers off so that is what you are seeing for the first part of this month except I forgot on the 3rd and did not shut my laptop down that night when i was through with it. I got laxed and kind of forgot until Aug the 10th when I received the "you have used 75% of your data" email from my provider again warning me of overage charges and wanting me to up my plan and buy more data. So I called my internet provider tech support again trying to find a way to get some real time knowledge of my data usage so I could trouble shoot what piece of equipment was the culprit. I have a dvd player that connects wifi and a TV that connects wifi in addition to my laptop and I live alone. I also have a desk top computer but I had stopped using it because I had my laptop so it stayed off and was actually not even connected at the time because I had moved it and just never set it back up. Talking back and forth to her finally convincing her that I wasn't using the data myself so she had me change the wifi password on the router which I did but talking to her I needed internet access so I put the password in my laptop only. SHe called me the next night but really could not do anything because we could not see the results for 2 days. When I logged in and saw the usage for the day that I had changed the password, I then turned off my laptop. I don't remember which day I did it but the next day or two I decided to leave the router on with none of my equipment connected to it. I had not put the new password in anything but my laptop and my laptop was powered down with the wifi antenna in the off position. When I checked that day there was no data usage. So in my mind leaving the router on with nothing of mine connected and having the data usage back down to null ruled out the neighbor hacking into my wifi. At that point I just started leaving the router off and only turning it on briefly when I need to check something on the internet. That is when I went looking for some freeware to let me see my data usage real time. I think I downloaded bitmeter on the 15th and connected the deskside back and installed bitmeter there too and I went looking for some help on the internet. I found this site and posted my question here on the 20th and literally those data usages that you see (except for one Netflix show on Sun.) were accumulated during my correspondence with you and downloading the utilities. I slide the wifi antenna to the off position when the laptop is on unless I am downloading another tool or uploading the output file. That is the data that you see from the 20th until today. Ok enough background tech support did not have me change my admin password on my router only my wifi password so I just went in and changed the administrative password on the router (the password was "admin"). I also changed the wifi password. I am not going to put the new password on any of my equipment and I will shut this computer down and remove the physical cable to the router. In two days when I can see it on the provider website to verify that the data usage for that day was zero. If it is zero I will again change the passwords on the router but i will turn on my laptop and that is the only thing I will put the password in. I will leave it on for several hours and then in two more days I will look to see what the data usage was for that day. Does that sound like a good way to pinpoint whether it is outside my house or on my laptop?
