excuse me.
im using BT 5 R1 G64, and my wifi card is Broadcom Corporation BCM43225 802.11b/g/n (rev 01).
I have checked the Wiki http://www.backtrack-linux.org/wiki/..._working_cards, that my Wifi card do support wifi connection.
but, i can not detect at wifi at all
i have ifconfig -a, buat there is no list for my wifi card.. there are only lo and eth0. eth0 is for my LAN card.
i have tried the
1./etc/init.d/networking start buat it gave me a warning like this

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service networking start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start networking
networking stop/waiting

no problem at connecting wired connetion at all, i can connect easily @ gui wicd.

can you guys tell me the solution is? or from where exactly i must start searching?
i have been trying installing the ndiswrapper due to install the broadcom driver but got error such Error: unable to find a version of ndiswrapper!

thx in advance
