I work in a small office with a single ethernet connection into a wireless router. We've noticed that the data usage is much higher than expected and I'm trying to figure out why.
We've changed the password to ensure (as much as you can) no-one that is not supposed to be is connecting.
What I'd really like to do is buy a new router (the old one's about 5 years old) that allows for reporting on data usage on a client per-IP address.
Does anyone know of such a thing?
