J'ai ajouté net.wlan0 à mon runlevel default, et quand je démarre, je peut ensuite acceder au réseau. J'ai tout de même un petit warning :
* WARNING: netmount is scheduled to start when net.wlan0 has started.
Pas bien compris sa signification... Le problème vient du fait que quand j'essaye de démarrer (si je ne la met pas dans le runlevel) / redémarrer (si ca connexion plante) l'interface wlan0, j'obtient des erreurs :
# /etc/init.d/net.wlan0 restart * Unmounting network filesystems ... [ ok ] * Stopping wlan0 * Bringing down wlan0 * Stopping udhcpc on wlan0 ... [ ok ] * Shutting down wlan0 ...

Et bien sur, aucun accès au réseau :/ J'utilise le driver ipw3945, wpa_supplicant, un portable samsung Q35 et j'utilise la configuration suivante :
cat /etc/conf.d/net modules=( "ifconfig" "!iwconfig" ) modules_wlan0=( "wpa_supplicant" "!iwconfig" "udhcpc" ) wpa_supplicant_wlan0="-Dwext" wpa_timeout_wlan0=60 config_eth0=( "dhcp" ) config_wlan0=( "dhcp" ) dhcpcd_eth0="-t 3" preup() { if test ${IFACE} = "wlan0" ; then /sbin/ipw3945d modprobe ipw3945 sleep 5 elif test ${IFACE} = "eth0"; then modprobe b44 sleep 5 fi } postdown() { if test ${IFACE} = "wlan0" ; then /sbin/ipw3945d --kill fi }
Merci d'avance, NaPs.
