[ubuntu] Intel Centrino Advanced-N 6230 not recognized

view full story

http://ubuntuforums.org – I'm running Ubuntu 10.04 via Wubi and my Intel Centrino Advanced-N 6230 wireless card seems not to be recognized. I've found threads talking about this issue but I don't understand what I'm supposed to do. I can't find drivers for it. I did this: sudo apt-get install linux-backports-modules-wireless-lucid-generic because the internet told me to but it seems not to have had an effect. Please help!? I'd really appreciate it.
