After my lasst STABLE upgrade it sseems that service has problems starting the wpa_supplicant.wlan0 daemon at startup. I have to start it by hand with:
service wpa_supplicant start
The werid thing is that in /etc/init.d I have two identical scripts: wpa_supplicant and wpa_supplicant.wlan0, but the latter (that is the one started during boot), fails with:
erro /etc/in : no such file or directory.
