Bonjour,

lance depuis une console : dmesg
Est ce que tu as installé le iwl4965-firmware ?
Oui, j'ai installé iwl-4965 firmware.

Je n'ai plus de message d'erreur au boot et ma carte wifi a même fonctionné une fois ... puis plus.

Je mets mon dmesg ici :

je vois pas de raison pour laquelle le wifi ne fonctionnerai pas... (hormis un bug du kernel ?, tu confirmes qu'il fonctionnais avant ou sur un kernel précédant ?)
Oui, il fonctionnait (et fonctionne toujours d'ailleurs) sur le kernel d'avant la mise à jour.
De toute façon, je vais faire une installation de Werewolf depuis 0 la semaine prochaine. On verra alors ce que ça donne.

Et alors ?
Cela donne quoi ?

Merci
Plus aucun problème sous F8. Tout marche à merveille.
Il est parfois possible dans le cas de ce chipset que le hardware scan soit instable...
Il est possible de desactiver le hwcrypto voire le disable_hw_scan dans les options du module/
Cela donne dans le fichier /etc/modprobe.conf

J'ai testé, mais le problème subsiste. j'ai toujours une déconnexion, aléatoire avec le message : "Feb 10 23:09:55 localhost kernel: iwl4965: Microcode SW error detected. Restarting 0x2000000."
