My wireless usb network adapter is constantly using ~100bytes/s even when there is nothing I can think of that needs to talk to the internet. Is there a way to find out what programs are using the internet?

An easy to see what is going on would to use wireshark.


sudo wireshark

You might need to install it first with the package manager.

I could be wrong, but there is always a small amount of traffic in a wireless network, basically to maintain connectivity. For instance, there is the beacon frame:
