Promiscuous mode is still a thing on wifi, but in order to capture traffic intended for other stations you need to capture the key exchanges between the other stations and the AP when they handshake, otherwise you will not be able to decrypt the traffic. It also uses WinPcap to capture network traffic; WinPcap does not support monitor mode (unlike libpcap on some UN*Xes, which does support monitor mode in newer versions), and, while WinPcap supports promiscuous mode, it doesn't do so if the driver doesn't support it, and few if any 802. The problem is that tcpdump itself turns promiscuous mode on so ipv6 starts working immediately and until the reboot.
