I need to know which user in my LAN is using up my DSL bandwidth. I only have limited DSL bandwidth (1.5Mbps) and have 10 users. I could not setup the users' computers to block torrents or video downloads. I have to control it from the router. I tried blocking off high numbered ports and also using OpenDNS.
But still, it seems someone seems to be hugging the bandwidth. Thus it would be great if I find out who it is and just talk to the guy.
Anyone knows an app that can find out who in the LAN is hugging the bandwidth?
