Hello, yes I am new to backtrack and I'm having problems with my linksys AE1000 usb wireless card. It falls under Ralink RT2870 and is recognized by my Backtrack 4 R2

lsusb Bus 001 Device 006: ID 13b1:002f Linksys AE1000 v1 802.11n [Ralink RT2870]

I have found threads here similar to it but they are all on Backtrack 4 R1 and are a bit old.

The firmware is up to date as well.

I find on threads to enable it by typing the command "ifconfig ra0 up" but I get:
ra0: ERROR while getting interface flags: No such device

I'm not really sure where to go from here.
Thanks for the help.
