Has this behavior changed recently? e.g. Has a patch been sent recently which will correctly enforce the rule mentioned above, but has not yet appeared in wireless-dev? I have removed the IEEE80211_HW_WEP_INCLUDE_IV flag from rt2x00 because hardware encryption is not implemented and the result seems to be that WPA connections will fail. I have already confirmation from 2 users who reported that with the flag set WPA software encryption will work, while without the WPA the encryption will fail. I have CC'ed Mattias, so if you need debugtraces he will be able to provide them. Another thing that is odd in this case is that the name suggests that only WEP is affected but apparently can break WPA. :S Ivo - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
