Subject: [Wireshark-dev] Wrong FCS in 802.11 capture

Can anybody verify the attached live capure I did just now?
All the frames in the capture seems to have wrong Frame Check Sequence

numbers. The capture was done with latest AirPcap on a Win-XP SP3 box running

the latest svn version of WireShark. Also verified with tshark.

They definitely look like junk... did the capture contain *only* such errored frames?

Which AirPcap adapter are you using (Classic, Tx, Ex, Nx)?

Have a nice day
