WiFi not working in Backtrack 5r3 Acer Aspire V3-571 Laptop having “Broadcom Corporation NetLink BCM57785 Gigabit Ether” integrated wireless card

I have installed backtrack 5r3 in one hard disk partition alongside with windows7 in another partition in Acer Aspire V3-571 laptop having "Broadcom Corporation NetLink BCM57785 Gigabit Ether" integrated wireless card. My problem is I could not make WiFi working in my laptop even after trying a lot of command and methods found by googling. I downloaded tg3 driver from broadcom website and hopefully installed it but all in vain. In some forum I found that some guys having the same issue with Broadcom 43XXX seriers wireless card had fixed their issue by using some sta driver package by broadcom specific for 43XXX series, but I noticed I have 57XXX series wireless card not the same. I could not find any working solution for BCM57785 wireless card. Here's what I did...... root@bt:~# cd /lib/firmware root@bt:/lib/firmware# unzip linux-3.133d.zip Archive: linux-3.133d.zip creating: Server/Linux/Driver/ inflating: Server/Linux/Driver/ChangeLog inflating: Server/Linux/Driver/README.TXT inflating: Server/Linux/Driver/tg3-3.133d-1.src.rpm inflating: Server/Linux/Driver/tg3-3.133d.tar.gz inflating: Server/Linux/Driver/tg3_sup-3.133d-1.ISO.tar.gz root@bt:/lib/firmware# root@bt:/lib/firmware# rpm -ivh tg3-3.133d.src.rpm The program 'rpm' is currently not installed.
