           Summary: ambiguous value for radiotap datarate
           Product: Wireshark
           Version: 1.1.x (Experimental)
          Platform: x86
        OS/Version: Windows XP
            Status: NEW
          Severity: Major
          Priority: Low
         Component: Wireshark
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: iodavide@xxxxxxxxx


Build Information:
Paste the COMPLETE build information from "Help->About Wireshark", "wireshark
-v", or "tshark -v".
--
If you select to display a custom column with parameter "radiotap.datarate"
from "preference --> column" menu, the displayed column shows values exactly 
double than value shown in "packet details" pane inside "Radiotap Header".

For example if "Datarate" value shown in the "packet details" pane 
inside "Radiotap Header" is 3.0Mb/s you'll see 6 in the column

The value in the packet details pane is probably the accurate one.
If you see in epan/dissectors/packet-radiotap.c that the call for adding the
datarate to the protocol details pane divides the value rate by 2.
The custom column code is probably confused by this.
