This is a must have program for people using LinkSys Cable/DSL routers. If you do not have said router, this program will be of no interest to you (except maybe if you need source code examples) This was developed to watch the broadcast data from a linksys router and report it back to you
Is this what you're looking for?

Hope it works.

Also, try this Google search (that's where I got the link above)
