I want to check my bandwidth usage in details incoming and outgoing if it's possible site wise ? Do you guys know any good tools for this ? Preferably free but any trail versions are fine too. It seems somethings not right about usage.
I want to find out who's the culprit ) Only I use the router and Wi Fi pretty well password protected. I don't think anyone stealing from it. So it has to be a software or a website I use.
