Given that Rogers upgraded you router I assume now you have better speeds? Given that is true your household can likely stream much better than before?
I do not think the Xbox gaming is the issue, we have Xbox, Wii, PS3 and all get used online when grandkids are over. Barely blips on the usage radar.
As I said before 6GB in a day is a lot. She (or someone connected to your router) is streaming video/music almost for sure. I'm sure you can leave certain devices off for a day and check your usage, likely can narrow it down that way. Is she perhaps streaming on her phone while playing Xbox?
Only other alternative is to pay for unlimited bandwidth.
FYI, surfing the web, etc (non media streaming) would likely not even use a GB in 24 hours so use that info to help you determine source.
