any app to track what apps are using wifi?

I am having issues with my home wifi and when I check the DD-WRT logs I am seeing that it is my mobile that is causing the problem.

So I was wondering if there was a way to tell what app was using the wifi connection at a given time. This way I can correlate the network errors to the app. I could disable each app one at a time but that wold take a long time.

I've never done this myself, but maybe a logcat would capture the information you need. Maybe someone can add some additional info.
