Hi, I have some questions about Wireshark that I hope I get answers for.
Can Wireshark be used to view whatever is being sent in a WiFi network? In other words: If I installed Wireshark on my computer, can I view whatever other users on the same WiFi network are doing? Can I record their Skype calls and videos? If so, Isn't there an application other than Skype that Wireshark can't get its data (text, voice, video)?

Yes, you can record everything that is sent over the air, as long as you have your WiFi adapter(s) tuned to the channels the others are sending on (usually the channel used by the access point(s)). You can record all applications that send packets.
Sounds too good to be true? It is. Because all of those packets will be at least encrypted once, since most applications use encryption like HTTPS/SSL by now. Twice, if the WiFi is encrypted, too. So yes, you can capture it all, but reading it in clear text is another matter entirely.
