802.11n 108Mb/s radiotap packet
Build Information:
Running on Windows XP Service Pack 3, build 2600, with WinPcap version 4.1.2
(packet.dll version 4.1.0.2001), based on libpcap version 1.0 branch 1_0_rel0b
(20091008), GnuTLS 2.8.5, Gcrypt 1.4.5, with AirPcap 4.1.1 build 1838.
Built using Microsoft Visual C++ 9.0 build 30729

using wireshark for wlan sniffing I noticed that some data rates from the
radiptap header are not reported correctly.
I used different wireshark versions from 1.2.x up to 1.4.x on windows xp and
linux (CentOS). All showed the same problem.
The attached packet was send using a datarate of 108Mb/s. The corresponding
byte in the radiotap header is 0xd8 hex, which is 216 dec.
The rate is given in multiples of 0.5 Mb/s.
The interpretation by wireshark of this rate is 13.0 Mb/s.
