I think I've managed to get my atheros to work, the iwconfig command show the wlan0. I had no luck using the wpa_supplicant though, my passphrase is something like "Hir Noue Frig Wasc"; and when I type sudo wpa_passphrase mynetwork mykey it says "passphrase must be 8..63 characters. I remind you that I'm really new to this, thank you for your help and patience.
