Hello again. I thought it would be cool to see what other people were doing on their internet-capable devices for fun, so I Googled for what packet sniffer I should download. I wound up downloading several, all of which had the same problem: They would not work. The field where it shows you what it found was blank in every program I tried. We have my Mac, a PC, and two iPhones on our WiFi. Absolutely nothing gets through from any of them. I have the network interface set to en0 for all of them, does that make a difference? I have also rebooted and reinstalled. Please help! Thank you!
