I have a W/L AP set up on my home network and I really don't mind if some of my neighbors use it every so often as long as they don't abuse it. I think, though, that a lot of the time they don't know they're on my AP. I want to be able to have a message pop up on their computer when they tap into my signal that just tells them that they've entered so and so's network and outline what is and is not acceptable use. Is there a way to do this?
