What wireless NIC are you using? Is any security in place? what do you get with iwlist wlan0 scan?

yes this is a secured network.

 lspci | grep Broadcom\ Corporation gave the following result
03:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

debianuser:/etc/init.d# iwlist wlan0 scan gave the following result
wlan0     Interface doesn't support scanning : Network is down

I have downloaded the following driver
CARD: Broadcom Corporation BCM4312 802.11a/b/g (rev 02)
Driver: sp36689.exe from the url ftp://ftp.hp.com/pub/softpaq/sp36501-37000/sp36684.exe located at the site

As far as I know the most broadcom NIC's are supported directly by Linux. So there is probably no need to use ndiswrapper for this.

Use apt-get or if you are using a GUI the package manager GUI tool your are used to use and search for broadcom, then install what it finds and reboot. Also install wpa-supplicant, as that is required to connect to secured LANs (but first try connecting with no security set on the router to test the system). If you get a connection, re-enable WPA on the router and configure WPA_Supplicant to work with your router. Check the readme's on how to setup the configuration file (there are also examples you can copy, modify and use).
