```

J'ai installé un kernel alternatif qui est sencé embarque les dernier drivers intel : [Xanmod](https://xanmod.org/) qui monte le kernel en version 6.1.0 mais sans succés.

J'ai essayé également de rajouter le firmware en suivant les instructions d'[Intel](https://www.intel.fr/content/www/fr/fr/support/articles/000005511/wireless.html), j'ai toujours les mêmes soucis.

Donc je demande a plus expérimenté que moi ;)
Avez vous une idée ?

Bonne journée
