I'm just a server support engineer so I have no clue in networking, so I need you help to assist me in what software or technology to find which IP address in my network is consuming the largest bandwidth ?
I have extended the network bandwidth for Guest wireless from 10 MBps to 20 MBps but it is still maxed out.
Note: all of the network switch and WLAN AP are Cisco brand, the Firewall is Juniper brand.
If possible the solution is the freeware ones or not more than $250 in terms of software license.
I have enabled that technology and then use PRTG in the past but don't know how to interpret ?
