Which STA firmware version are the cards using? Is it different between
the STAs that use RTS/CTS and that don't? If I remember correctly, there
were some changes to rate control algorithm in the firmware and it may
have involved use of RTS/CTS in some cases. If the firmware versions are
different, I would assume this would be reason for the behavior you are
