There is no reason wireless shouldn't work, but i know there was some issue with some wireless cards and winpcap driver -- was it intel wireless cards?
The winpcap people are the ones who may know about a workaround.
Yes. It's Intel(R) Dual Band Wireless AC3165. Based on WinPcap FAQ at
Q-16: Which network adapters are supported by WinPcap?
A: The WinPcap device driver was developed to work primarily with Ethernet (10/100/1000) adapters. Support for other MACs was added during the development, but Ethernet remains the most tested one.
The overall situation is:
Windows 95/98/ME: the packet driver works ok on Ethernet networks. It works also on PPP WAN links, but with some limitations (for example it is not able to capture the LCP and NCP packets). FDDI, ARCNET, ATM and Token Ring should be supported, however we did not test them because we do not have the hardware.
Windows NT4/2000/XP/2003/Vista/2008/Win7/2008R2: the packet driver works ok on Ethernet networks. As for dial-up adapters and VPN connections, read Q5 and Q6. As in Win9x, FDDI, ARCNET, ATM and Token Ring are supported, but not tested by us.
Wireless adapters: these adapters may present problems, because they are not properly supported by the Windows Kernel. Some of them are not detected, other don't support promiscuous mode. In the best case, WinPcap is able to see an Ethernet emulation and not the real transiting packets: this means that the 802.11 frames are transformed into fake Ethernet frames before being captured, and that control frames are not received.
For real wireless capture, CACE Technologies offers the AirPcap adapter, specifically designed to sniff 802.11 traffic, including control frames, management frames and power information. AirPcap at this time is the only solution for capturing raw 802.11 traffic with WinPcap. More details can be found on the AirPcap product page.
