Are you useing wpa_supplicant (i.e. ifconfig_ndis="WPA DHCP") for this
wireless connection?

If you are using wpa_supplicant, then try to run it manually:
# wpa_supplicant -B -q -i ndis0 -D ndis -c /etc/wpa_supplicant.conf -P

You should get this error:

NDIS: Failed to get adapter list (PacketGetAdapterNames)
Failed to initialize driver interface

This error is caused by the MFC of wpa_supplicant to version 0.4.8.
And the wrong return values being returned by PacketGetAdapterNames.

In usr.sbin/wpa/wpa_supplicant/Packet32.c, the PacketGetAdapterNames
routine should be returning boolean value, but instead it is returning
a zero, EIO, ENOSPC, and ENOMEM.

  You need to replace the return(0) with return(TRUE), and you also
need to replace return([EIO,ENOSPC,ENOMEM]) with return(FALSE).

After you have made these changes, just do a make clean ; make ; make
install ; make clean to rebuild and install wpa_supplicant.  Then use
the above command again to start wpa_supplicant.

No electrons were mamed while sending this message. Only slightly bruised.
