I have the 4G LTE wireless device with voice as my home internet. My computer was off over the weekend, and I checked my data usage on Monday morning and it used 3.2GB on Saturday and Sunday. I am trying to find out what is using so much GB data. I do use a VPN and intially thought it was that, but the VPN was disconnected on Friday night and left off all weekend. I checked my Direct TV connection, and my TV is not connected to the internet via wireless. Has anyone else had problems with a lot of GB data usage for no apparent reason? My wireless device is password protected, and I don't live near people to even be close enought to use my WIFI. I am wondering if I can figure out which IP address is using the data so I can track it down. I am up to 24 GB of usage in as many days, and I don't use the internet that much in the house - primarily my iPhone, which shows usage of only 400MB in the 24 days. Please help.
