So i've been following a few youtube guides along with forum guides on obtaining the wep key from a router. I use a Windows 7 Home Premium 32bit, and I just downloaded Windows Virtual PC to run with Backtrack 5. My laptop is a Compaq CQ40 and has an internal Broadcom 4322AG 802.11a/b/g/draft-n Wi-Fi Adapter. I read somewhere that USB adapters are needed (?) so i bought a Realtek RTL8188SU Wireless LAN 802.11n USB 2.0 which is a wireless usb network adapter. I have also modified the settings so Realtek and Broadcom are both detected using Settings in Windows Virtual PC.

I run startx in Backtrack 5, Launch Konsole, and as i type airmon-ng, i see 3 columns Interface Chipset and Driver. however, nothing appears under interface or chipset or driver, as is demonstrated in the videos. Would anyone please direct me to my mistakes?
