ndiswrapper problem with Wireless

[macdowell.smd@dpf.gov.br]

I have hp pavillon tx1420us with
Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (recv. 03)
Broadcom 4321AG 802.11a/b/g/draft n Wi-Fi Adapter
-----------------------------------------------
I'd ndiswrapper installed but:

hp:/home/mac# iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.
------------------------------------------------
I'd checked:

hp:/home/mac# lsmod | grep ndis
ndiswrapper           216064  0
hp:/home/mac# ndiswrapper -l
bcmwl6 : driver installed
	device (14E4:4328) present (alternate driver: ssb)
hp:/home/mac# cat /etc/modprobe.d/ndiswrapper
alias wlan0 ndiswrapper
hp:/home/mac# dmesg | grep ndisw
[   17.473835] ndiswrapper version 1.53 loaded (smp=yes, preempt=no) [  
17.589837] usbcore: registered new interface driver ndiswrapper
hp:/home/mac#

---------------------------------------------
 also seems OK <modinfo ndiswrapper>

Any help?

Thank you
