Sure, I can retrieve the info from my cable modem. I also tried wireshark. I then decided looking at the console was much "quicker" for me. But if I'm in a situation where the guests are constantly created and there is a need for semi-automatic retrieval of guest's IPs, I would spend some time for that. Akemi
