On most WIFi cards you need special drivers that promiscuous mode can be enabled.

Make sure you run Wireshark with administrative privileges by holding CTRL + SHIFT when you run it, or right-clicking it and pressing "Run as Administrator".

Promiscuous mode is used to make the wireless card listen to everything that it can understand, not just information that is addressed to it.
