I'm not a 1337 hacker or anything but when I check my LAN info on my router I see a couple people on my network that I don't know. Before I change my WPA password again, is there anything I can do to mess around with these guys? I don't even know how to kick them off the network or view what kind of traffic they are viewing. I have Wireshark but have no idea how to get the packets to make sense to me. I have dd-wrt firmware, if that matters.
