In the grand scheme of things it's insignificant but I'm curious as to what may be causing the activity.
The router is left switched on, but the PC is off. Clearly it's possible that someone outside the church is using it for their own purposes but as the usage is so small I'd wonder why they bother.
I'm wondering if the router itself creates some traffic, if so what for and would it be enough to account for this?
We have more and more laws, and less and less enforcement
