The problem is that when the card is in sniff mode the transmitter is disabled. So I don't let the card go in sniff mode. In theory and probably with slow performance we could bounce the card between sniff mode and then not sniff when we transmit a packet but I don't know if it is worth it. This bug has confunded people debugging a Aironet network with tcpdump etc. I've implemented WEP in the driver and ancontrol. It supports the various WEP modes and setting the various keys. Similar to the setup options in the Windows WEP config utility. It works with a bunch of cards that I have access to. Other people have successfully used this. >How-To-Repeat: >Fix: http://www.ambrisko.com/doug/an.patch.wep Apply at the base of the src tree (ie /usr/src). >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
