Unexplained data use
My wireless router (ASUS) has a Traffic Analyzer which shows real time and historic data usage by device and by APP. It's very impressive.
Seeing my data increase lately prompted me to try to understand this.
I isolated one device, an HDTV in a living room. With all my other devices turned off, I turned the TV on with Roku and watched one hour of live local news on HULU.
The data showed up on my router exactly at 1pm which I switched on the device at a rate of 3.5GB/hr. I turned off the device at 2pm.
I checked the router data a few hours later for that device continued to use data at 4GB/hr from 2pm to 5pm, when it the data chart dropped to zero.
I have repeated this result on two other HDTVs on our network.
I have contacted HULU, Netflix, Roku, Comast, ASUS, and Akamai.net.
No one can explain why this is happening.
If data were free, I wouldn't care, but aside from the cost, I am curious what causes this to occur.
I was told by Roku that when the power button is pushed to turn off the device, that stops the data feed to that device.
Any idea from the community? Anybody else experience this?
