I just installed Crunchbang 10 to my Laptop in dual boot with win7. My wlan card is a Intel(R) Centrino(R) Wireless-N 2230. I saw I had no wifi, so I tried to install the driver from here by extracting them and typing:
sudo su cp iwlwifi-2030-6.ucode /lib/firmware
After that, I rebooted and still had no Wifi. Why?
