If this is on Windows, then it might be a known issue, namely that the
drivers for wireless cards on Windows are sometimes rather uncooperative
with NDIS drivers such as WinPcap:

(see the item at the end:

	In the case of wireless LAN interfaces, it appears that, when
	those interfaces are promiscuously sniffing, they're running in
	a significantly different mode from the mode that they run in
	when they're just acting as network interfaces (to the extent
	that it would be a significant effor for those drivers to
	support for promiscuously sniffing and acting as regular network
	interfaces at the same time), so it may be that Windows drivers
	for those interfaces don't support promiscuous mode.)
