Are you trying to break your own network? So you know the real WEP key? If your 64 bit key is for example AA:BB:CC

D:EE do this:

./weplab -r ./pcap.log --debug 1 --debugkey AA:BB:CC

D:EE ./pcap.log

and try also the same with --fcs, --prismheader or both

./weplab -r ./pcap.log --fcs --debug 1 --debugkey AA:BB:CC

D:EE ./pcap.log
./weplab -r ./pcap.log --prismheader --debug 1 --debugkey AA:BB:CC

D:EE ./pcap.log

./weplab -r ./pcap.log --fcs --prismheader --debug 1 --debugkey AA:BB:CC

D:EE ./pcap.log

The one that gives you the message "Key correct!" is the one that has the right commands.
You can also use ethereal with your captured file and see with it if it has the prismheader.
