Building or securing wireless networks can be a challenge when your tools don't understand radio waves. AirPcap enables troubleshooting tools like Wireshark (formerly Ethereal) and WinDump to provide information about the wireless protocols and radio signals. AirPcap's dedicated receiver can provide crucial information that other solutions can't. AirPcap is the first open, affordable and easy to deploy WLAN (802.11b/g) packet capture solution for the Windows platform. AirPcap comes as a USB 2.0 adapter, and it's been fully integrated with WinPcap and Wireshark: it enables you to capture and analyze 802.11b/g wireless traffic, including control frames, management frames and power information, using Wireshark on your Windows laptop. AirPcap supports the following operating systems: Windows 2000, Windows XP 32 and 64 bit, Windows Server 2003 32 and 64 bit.
