Just a quick FYI for those *true* WiFi packet analysis junkies out there – I installed OmniPeek Professional 5.1.4 on my HP 6910 laptop.  The software “works” with embedded Intel wireless NIC, but reports invalid data rates for 802.11n traffic.

The work around that I came too was to purchase a 3rd party, dual-band 802.11n USB adapter that has a supported API within the OmniPeek software.

I also have an AirPcap Nx device from CACE Technologies that I like *very* much – USB form factor that allows for wireless packet capture in Windows.  AirPcap integrates directly into Wireshark, which is nice since I “grew up” taking wireless captures in Lib PCAP format under Linux and looking at them in Ethereal.
