Couple month back my internet data usage went up about twice, I though because 4K programs became popular on netflix and such. last month I received warning from comcast that my 1Tb tier has been reached so I started investigating.
2days ago I switch off mt router yet 6hours later 4more gigabytes has been recorded on my account.I went to bestbuy and bought new cable modem with build in router . as of this morning 11 gygabytes appeared on the counter.
SSID and password has been reset twice and I don`t see any unfamiliar devices on my network.
I don`t ability to track what exactly every device doing on the network but I can see that all 2 smart TV is off. I only surf internet on one device and no big files downloading nor uploading.
Comcast suggested to use their modem/router instead that data usage can be traced to particular device.
I disliked the idea of additional change but was told on xfinity xFi app that new compatible router is on them.
Is there anyone else who has too much data usage?
