Bonjour,
Tout est dans le titre, mais je vais détailler.
Déjà en 17.10 j'avais eu le même genre de problème, que j'avais résolu grâce à votre aide, mais aujourd'hui sur Focal Fossa, il semble que les manips ne fonctionnent plus, et j'aimerais quand même ne pas avoir à repasser en 18.04 pour avoir une LTS.
Pour résumer le problème, le WIFI s'active et détecte comme il faut pendant quelques secondes, puis plus aucune détection, un message d'erreur et plus rien.
Voici le retour de mon wificheck et quelques pistes explorées :

Voici enfin un extrait de mon dmesg :

C'est ce qui apparaît quand l'erreur survient, ce qui m'aiguille vers l'ASPM, mais je ne m'y connaît pas du tout assez.
Merci d'avance pour votre aide!
