Unusual data usage

[AndrewM75]

Hi,

I am hoping someone can help here as I am lost for where our data is being used.

I activated a new mobile data package about two weeks ago and we have apparently used 85% of 200gb in that time. My system setup is Netgear LB2120 LTE modem set to Bridge mode and Netgear D6400 router. I have been through all the checks I know to do and changed all passwords/security/ etc. I have also switched on the traffic monitor included with my router.

The strange part is that the D6400 traffic monitor shows that we have used 10gb this week but the LB2120 and Telstra site are showing more like 10gb/day. I also notice that even when everything is turned off Telstra Tools is showing logs of 117mb begin used roughly every 4-5 min??
