adhoc doesn't work with centrino

[jqdkf at army.com]

Hi,

My wireless card is "Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter".
With ndiswrapper, it works fine in BSS mode, but I can't make it work in
adhoc mode. Here is my configuration:

$ ifconfig ndis0 inet 10.0.0.1 netmask 255.255.255.0 \
        ssid CACTUS mode 11b mediaopt adhoc up

ifconfig shows that

ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet6 fe80::204:23ff:fe60:9df1%ndis0 prefixlen 64 scopeid 0x4 
        inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
        ether 00:04:23:60:9d:f1
        media: IEEE 802.11 Wireless Ethernet autoselect (autoselect <adhoc>)
        status: no carrier
        ssid ""
        channel 1 authmode OPEN powersavemode OFF powersavesleep 100
        wepmode OFF weptxkey 1

With wicontrol ndis0, I can see that

Port type (1=BSS, 3=ad-hoc):            [ 0 ]

I don't know how to change the port type to 3. There seems no documentation
on that.

Also I noticed that, after I configured it to adhoc mode, the mouse doesn't
move smoothly, which doesn't happen in BSS mode. Is there anything that I 
can do to make it work?
