Bonjour à tous,
J’ai un problème assez étrange et qui m’inquiète un peu. J’ai jamais eu de soucis particuliers pour utiliser le wifi sur mon PC portable, un Dell G5 avec un debian buster et un noyau 4.19.0-5-amd64.
Ma carte wifi est une Intel Wireless AC 9560 et fonctionnait sans soucis avec iwlwifi.
Sauf que depuis hier l’interface wifi n’apparaît plus. Je n’ai pas fait d’intervention sur le hardware ni même fait de mise à jour software. Le soir il marchait bien, et le lendemain en rentrant du boulot plus rien.
J’ai eu un peu peur que se soit un problème matériel mais la carte est toujours détectée physiquement par le système.
Voila les infos qui pourrait être utile :

Il y a bien des erreurs avec le module iwlwifi mais j’ai du mal à identifier d’où elles pourraient venir.
