We have been away for the last few days - returning on Friday evening. I happened to check the usage on our broadband account and it showed data usage for the days we were away Tuesday through Friday of 2.77GB (Tue), 2.87GB (Wed), 2.55GB (Thur), 2.87GB (Fri). The house has been empty, no computers have been left switched on, but the router was left on. I can believe that there is a small amount of data interchange between the Plusnet Servers and the router irrespective of whether there is any user generated traffic. But 2GB plus every day, seems to suggest something else is going on. Any ideas from anyone as to what?
