I have a Mac Mini hard wired into my linksys (wired/wireless) network. I live in a close, urban neighborhood, and I would like to see which other neighbors are using are using my wifi, and possibly what they are doing since it is my network. (We don't have the best relationship.) It isn't illegal to spy on those piggybacking on your network, is it? I know you can look at router logs, but I'm not sure how on my WRT54G. I know about WEP and WPA and stuff, and turn it on when I need it. However, I have a 1Ghz TiBook that does not seem to be able to use Wifi with WPA enabled, so I can't leave it on. Any thoughts on this also? Thanks.
