[RESOLU] Wifi non fonctionnel au demarrage

Bonjour,
j'ai un DV9000 et une carte wifi integrée de type broadcom4312. Le wifi est configuré avec ndiswrapper et fonctionne correctement quand je le lance manuellement.
Par contre, j'ai un probleme au demarrage :
La carte wifi est bien reconnue mais la connexion ne fonctionne pas, j'ai le message :
ADDRCONF (NETDEV_UP) : eth0 link is not ready

Je suis obligé à  chaque démarrage en mode console de taper :
sudo ifdown eth0, puis sudo ifup eth0

Comment résoudre ce probleme ?

Merci !

Re : [RESOLU] Wifi non fonctionnel au demarrage

Re-Bonjour,
je m'auto reponds, donc pour ceux que ca peut interesser :
Sous Gnome, avec Network manager pour une connexion securisée en WPA en IP fixe(wpa_supplicant), mon probleme etait que la carte wifi broadcom 4312 (bcm43xx) etait bien configurée, mais que la connexion à mon routeur wifi n'etait pas operationnelle. Je devais par conséquent à chaque demarrage executer successivement (eth0 est mon interface wifi):

sudo ifdown eth0
sudo ifup eth0

ou

sudo /etc/init.d/networking restart

Après des recherches sur les forums et aucun résultat avec WICD (instable, connexion réussie au démarrage mais pas de résolution de noms...), j'ai trouvé la manip ci dessous pour qu'au démarrage ma connexion fonctionne (avec wpa_supplicant) :
1 - Créer un fichier wpa_supplicant.conf dans /etc
2 - Y placer (et adapter selon votre configuration) :

ctrl_interface=/var/run/wpa_supplicant

ap_scan=1

network={
    ssid="<votre_SSID"
    scan_ssid=1
    proto=WPA
    key_mgmt=WPA-PSK
    #psk="<Ma_clef_en_ascii>"
    priority=5
}

2 - Dans /etc/network/interfaces, en admettant que votre interface WIFI est eth0 :

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
wpa-conf /etc/wpa_supplicant.conf
address 192.168.1.9
netmask 255.255.255.0
gateway 192.168.1.1

et voilà... Maintenant en bootant ubuntu (sous gnome), ma connexion wifi est configurée et directement associée au SSID de mon routeur wifi.
pour ma part, j'ai l'impression que c'est wpa_supplicant qui ne devait pas être lancé avant la configuration reseau et du coup, l'association ne se faisait pas (ou etait rejetée...)

Bref, cette configuration à l'air de fonctionner parfaitement pour une carte broadcom 43xx associée à un routeur en WPA et une configuration ip fixe.

N'hesitez pas à me poser des questions ou a expliquer vos probleme du meme type dans ce post.

La prochaine etape est de savoir pourquoi j'ai des deconnexions intempestives (mais là, je seche...). si quelqu'un à la réponse ;-)

Re : [RESOLU] Wifi non fonctionnel au demarrage

ndiswrapper ou pilotes proprio?

a noter que networkmanager ne supporte pas les ip fixe!

Re : [RESOLU] Wifi non fonctionnel au demarrage

Salut,
c'est avec ndiswrapper. Par contre j'ai toujours des problemes au demarrage :
Tout parait ok apres un

iwconfig

. je vois bien la connexion active, mais un

ping www.google.com

est non résolu... un simple

sudo /etc/init.d/networking restart

permet d'avoir une connexion OK.
