My network has about 60 PC.
Internet has a SDSL 4Mo
In normal conditions (and at night when no one is connected) PING to www.google.com
is between 20 to 30 ms
During a download operation it can go to 60 to 150ms and then is goes back to normal 20 to 30 ms
SOmetimes, and that is my problem, it goes to up to 250 to 400ms (saturating Internet bandwith for many hours) and I cannot find the reason. I am sure it comes from a "IP device" (PC, smartphone, tablet..) since when people goes home at 18h and turn off the computers everything is back to normal
ANtivirus is Sophos and uptodate on all PCs
IS there and way, a tool (hardware of software) to point to the IP address while bandwith is saturated (Ping around 250 to 400ms) ? That will help me find the "culprit", the PC which is saturating bandwith
Is there another way to held me identify which PC is saturating the Internet Bandwith?
Can a Smartphone, tablet (connected in WIFI to the Network) saturate the Internet Bandwith?
Thank you for your help
