We have a wireless connection to our ISP which has been fine for the past few months. Over the last two months, however, our bandwidth has increased 500% resulting in extra charges from our ISP. I can’t figure it out – we have a linux gateway and firewall – doesn’t show any hacking – lots of outgoing activity on a Sunday’s though when our plants are closed.
I suspect either someone is stealing our signal or a user has downloaded Kazza or something like it. We have an internet monitor, but nothing has been detected.
Anyone have any suggestions?
