Monitoring internet usage? Programs using the internet
Lately, my internet has been slow. I'm on an unsecured network, but I never had problems in the past. How can I monitor what programs are using the internet or my internet usage? I want to see if someone is using my connection or if a program in the background is using the internet.
wireless or wired, because the majority of the devices use switching you will not be able to capture all the packets on your LAN without an intermediate device, or a switch capable of port mirroring. So in essence you need to be able to monitor between the router and your modem(DSL, cable). You can do this with a smart switch set to mirror, between the two and use wireshark to monitor the mirrored ports. Or put a pc with two nics between the to to bridge the network so you can monitor whats moving across the bridge.
People are probably using your connection to connect themselves, if you are using an unsecured network I recommend that you secure it. Your internet speed should be faster after this - if not, check what programs are running / using the internet.
If you are using a wireless connection - check your signal strength, if it is low, move closer to the router (so no walls are in the way).
