I am currently using a Linksys wrt54g wireless router along with a ARRIS CM550A Cable Modem that provides 12 MB/s download speed and upload speed of 1 MB/s.
The Internet connection is functioning well; however as soon as one of my roommates connects to the WiFi it gets extremely slow. I think that a torrent application is causing this; I am not sure though.
So I am wondering: is there a way to find out which IP address / MAC address is consuming the most bandwidth? Or which application is using a certain amount of bandwidth?
