>Description:
    The machine running windows is set to adhoc mode. 
    ssid is cat

    On FreeBSD machine, I type:
    ----------------------------------
    ipwcontrol -f /usr/local/share/ipw-firmware/ipw-i.fw
    ifconfig ipw0 mediaopt adhoc
    ifconfig ipw0 ssid cat
    ifconfig ipw0 192.168.0.1 netmask 255.255.255.0
    ifconfig ipw0 up
    -------------------------------------
    the led of wireless is on. 

    then the windows machine says that it has detected a wireless network..
    I choose join..and it said that the signal is very good.

    But the windows machine can not receive any packet...and it was sending packet continually. 

    when I
    ---------------------
    sysctl net.wlan.debug=-1
    sysctl net.wlan.0.debug=-1
    --------------------
    the first tty said that:

    "discard frame, not to bss"

    continually
    -------------------------------------
    I am sure that my wireless card is good, and the windows machine's setting is right,
    because the wireless worked when I run Windows.

    My machine is 

    IBM thinkpad T42
    and my wireless card is 

    ipw0: <Intel(R) PRO/Wireless 2100 MiniPCI> mem 0xc0210000-0xc0210fff irq 11 at device 2.0 on pci2
    ipw0: Ethernet address:xxxxxxxxxx



>How-To-Repeat:
    The machine running windows is set to adhoc mode. 
    ssid is cat

    On FreeBSD machine, I type:
    ----------------------------------
    ipwcontrol -f /usr/local/share/ipw-firmware/ipw-i.fw
    ifconfig ipw0 mediaopt adhoc
    ifconfig ipw0 ssid cat
    ifconfig ipw0 192.168.0.1 netmask 255.255.255.0
    ifconfig ipw0 up
    -------------------------------------
    the led of wireless is on. 

    then the windows machine says that it has detected a wireless network..
    I choose join..and it said that the signal is very good.

    But the windows machine can not receive any packet...and it was sending packet
    continually. 

    when I
    ---------------------
    sysctl net.wlan.debug=-1
    sysctl net.wlan.0.debug=-1
    --------------------
    the first tty said that:"discard frame, not to bss"continually
