I have a USB Wifi Antenna that includes a Realtek chipset rtl8191su (compatible with rtl8192su).
Unfortunately, the driver isn't included in BackTrack 4 even if this is a good widely spread chipset :

Single-Chip IEEE 802.11b/g/n 1T2R WLAN Controller with USB 2.0 Interface :Realtek

The Vista driver from Realtek website works perfectly.
The Realtek website doesn't offer any linux driver.

However, this driver is available on 2 websites :

The first one comes from Linux Headquarters - Kernel :

The 2nd one comes from Ubuntu :

I would prefer to run Backtrack 4 from a live cd.

Question :

I'm incapable of compiling and integrating this driver source into backtrack 4...

Can someone help, please ?

Thanks very much !
