Thank you for your reply. I was measuring total traffic over 24 hours. But it's a shared home network, so I could have had a number of interferences. I know it uses only kilobytes per share, but if you go through a thousand or so per hour, that becomes megabytes. Accumulate that over a month and it adds up to enough that it gets in the way of other uses I'd like to share my bandwidth to... Educational purposes, you understand.
