Can anyone help me to figure out how to use Wireshark to monitor all Internet traffic on my home wireless network? We use a Verizon MI424-WR FiOS Router to serve several laptops via Wifi. My son is on one of the machines, and we need to monitor his online gaming and make sure he is honoring our agreements. It has already resulted in him failing out of college and we are getting desperate. I have used Wireshark to monitor my OWN activity, but cannot figure out how to capture other IPs on the network. A coaxial cable connects to the router and we just use the wifi to get online. I am a networking newbie, but understand the basics. Can you please help? I am running Lion on a MacBook Pro; the kid uses a Windows machine. Keylogging software is not an option; he's too crafty for that.
