Bonjour,
Problème survenu soudainement en cours d'utilisation : coupure de réseau (ce qui arrive fréquemment), je vais pour reconnecter mais plus moyen d'activer le wifi dans network-manager (ligne du menu contextuel griséee).
Après redémarrage, plus du tout de connexion wifi dans le menu contextuel de network-manager.
Voici quelques retours de commandes, issues de mes premières recherches :
~$ lspci | grep -i network

Merci de votre aide.
