Hello everyone, i am new to linux and backtrack but quite proficient with technology. I just set up my dual boot system and acquired an alfa usb wireless adapter. My internal wireless adapter has already been deemed wlan0 leaving my alfa card as wlan1. But, for some reason when I try, iwlist wlan1 scanning, it comes back with no results saying that the interface doesn't support this...

I tried googling the problem but didn't find much so i decided to come here. Any help would be appreciated, thanks.
