I have Backtrack4 installed as a dual boot with Vista in my Acer Aspire 5315 laptop. I can connect to my access point with my inbuilt wireless Atheros AR5007EG wireless adapter by starting services/network and WICD. The problem I have is connecting my Alfa network RTL8187 wireless through WICD or wireless assistant. My Alfa network adapter works fine as I have used it with Aircrack-ng in BT4.
Thanks
