Tu as un support d'installation d'Ubuntu (DVD ou clé USB) ?

Pour appliquer la procédure > amorcer_sur_cd_ubuntu#amorcage et arriver à cette étape : essayer_ubuntu_sans_rien_changer_dans_votre_ordinateur et tester le wifi avec le noyau initial.

Je viens de tester avec un boot sur une clé USB de ubuntu 20.04 et la connexion avait l'air correcte a priori

Il faudrait avoir, pour comparer :

lspci -k -nn | grep -A 3 -i net

lsmod | grep cfg80211

rfkill list all

iwconfig

uname -r -m

ip -c a

dmesg | grep iwlwifi
