In my network there are around 450 users. We have taken a 4 MBPS RF connection for internet .Whole Lan is 100 MBPS and class -A network Id
But there is problem in network. People are not able to get good internet speed . But my router shows , full 4 MBPS usage .
there could be 2 reasons
1) some virus ..which is clagging the networkign with some unnecesaary packets
2) Few people are sucking the whole speed by somehow using torrents ,DAP etc..
Kindly help to identify the problem
Any software which can give me usage by each ip . Right now i am using Suid on Windows as my Proxy server
then one firewall is there . and last is Cisco router
