The exact same sequence of operations with a (Dell OEM) Lucent gold card works correctly. The equivalent sequence of operations under Windows 2000 with the Netgear card works correctly. I can only conclude that the code to set a 128 bit WEP key on Prism2 cards under FreeBSD is incorrect. wicontrol reports the correct value for the key, so the ioctls to read and write the keys at least are reading and writing the same bit of data. Traffic snooped off the Ethernet segment connected to the access point show corrupted frames that seem to match up in length and time to transmissions from the machine under test. That tells me the key is not being set properly. >How-To-Repeat: ifconfig wi0 wepmode on weptxkey 1 wepkey 1:0x00112233445566778899aabbcc on a prism2 card (with your access point similarly configured, of course). >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
