LM22 Plantage WiFi + freeze

[siphon]

Bonjour,
Depuis ma MAJ vers Mint 22, il m'arrive un souci étrange :
- tant que je suis en connexion filaire : aucun souci ;
- si je suis en WiFi :
1) le WiFi se coupe au bout de quelques minutes et disparaît du gestionnaire de connexions ;
2) le système se met progressivement en en freeze et finit par se bloquer, et je suis souvent forcé de l'arrêter en mode "bourrin".
Ces phénomènes arrivent beaucoup plus vite si j'ai le malheur d'aller sur google ou un de ses outils. Si j'arrive à ouvrir le Moniteur Système, c'est souvent le processus irq/16-iwlwifi qui occupe le plus le processeur.

Bonjour,
Si je comprends bien, c'est un problème avec le firmware inclus dans le noyau Linux ?
Est-ce qu'il faut que j'installe un noyau plus ancien, ou bien que je télécharge le firmware qui va bien et que je l'installe à la main ?

[siphon]

Bon, après plusieurs MAJ du kernel sans que ça change grand chose, j'ai fini par ré-installer le système à partir d'une clé USB (à la place de celui qui était issu de MAJ successives) et le WiFi semble fonctionner à nouveau normalement.
