Hi,
  In the hardware support page, I found FreeBSD 8.2 suppots "Intel PRO/Wireless 3945ABG MiniPCI network adapters ( wpi(4) driver)", also in the "WPI(4)" page, I saw "The wpi driver provides support for the Intel 3945ABG Wireless network adapter wpi supports station, adhoc, and monitor mode operation."
  But after I had complied kernel according the wpi(4), the WLAN card cann't suppots adhoc.
  Please see below:

wpi0 at pci0:16:0:0:	class=0x028000 card=0x135d103c chip=0x42228086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel 3945ABG Wireless LAN controller (10208086)'
    class      = network
[root at fysky ~/tmp]# ifconfig wlan0 list caps
drivercaps=181e001<STA,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2>

  "IBSS" is not contained!
