Connexion WIFI

folepy · Le 21/06/2009, à 12:14

Bonjour à tous,
Depuis 2 jours maintenant impossible "d'attraper" une connexion wifi. Je vois des réseaux mais impossible de m'y connecter. Je n'arrive entre-autre pas à me connecter en WPA à une freebox. Tout marchait très bien avant. La il me demande 2 ou trois fois mon mot de passe puis rien. Il mouline! Pour le réseau Freewifi sans mot de passe, idem il mouline sans jamais s'y connecter.
Tout fonctionne en Ethernet!
Vous vous voulez un retour de commande pour voir ma config?
Merci

Hello, j'ai exactement le même souci sous jaunty 64bits, tout fonctionnait impec out of the box niveau wifi, j'ai réinstallé et là plus moyen d'accrocher un réseau.
J'ai fait une manipulation qu ia failli marcher :
1) Installer wicd (ne fonctionnait pas mieux)
2) Désinstaller Wicd et réinstaller network-manager
3) Rebooter
4) Se connecter
5) Sauf que si je reboot après retour à la case départ...

hello

Si tu as la possibilité de relier l'ordi au routeur, par cable, le temps de faire ce qui suit:
[Mise à jour de tout]
{à entrer dans un terminal, une ligne=une commande}.

sudo -s
aptitude update && aptitude safe-upgrade
aptitude full-upgrade
aptitude install build-essential linux-restricted-modules-$(uname -r)
aptitude install linux-headers-$(uname -r)
aptitude autoclean && update-pciids && update-usbids
reboot

Merci pour cette réponse...
Sinon une question bête...comment booter sur mon ancien kernel?
Merci

folepy · Le 22/06/2009, à 23:29

Bon j'ai trouvé pour le kernel (oui ce n'était pas trop dur)!
Et oui le wifi marche en bootant sur un Kernel plus vieux... Bizarre comme mise à jour!
