WIFI Intel(R) Wireless-AC 9462, REV=0x318 Ubuntu 18.04 fonctionne pas

LaurentDelaon

xubu1957 a écritTu as ton 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 en session-live.

Ça ne marche pas avec le livecd. Mais je précise que cela a fonctionné.

xubu1957

Enlève le support.

Essaye alors avec le noyau 5.4.0-56.

Le 29/05/2017, moko138 a écrit
Démarrer sur un noyau précédent

- redémarre en tapotant les touches Majuscules ou Echap
- à l'apparition du menu de grub, descends avec la flèche bas, sur la ligne :

Linux previous versions

Advanced options for Ubuntu

- valide
- choisis un noyau autre que le plus récent.
- valide et laisse le pc poursuivre son démarrage.

LaurentDelaon

j'ai testé 4.15 ,5.56 bref : ça marche pas

xubu1957

Que renvoie :

dkms status

?

Tu as vu au #20, la réponse de Nico ?

LaurentDelaon

Oui mais je ne sais pas trop comment faire pour avoir une version ancienne ?

LaurentDelaon

Je suis d'accord mais est-ce plus ancien ?

xubu1957

Au #3, on voyait une itération 9000-pu-b0-jf-b0-46.ucode :

[    6.358621] iwlwifi 0000:00:0c.0: loaded firmware version 46.6bf1df06.0 9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm

LaurentDelaon

J'ai remis code

cp iwlwifi-9000-pu-b0-jf-b0-34.ucode /lib/firmware

bon toujours rien.

Pfuiiii.

xubu1957

Avec redémarrage de l'ordi et de la Box ?

LaurentDelaon

Rien.

Il n'y a pas d'interface wifi genre wlan0.

xubu1957

Tu n'as pas une clé wifi ?

LaurentDelaon

non sinon j'aurais fait un test ; je peux en acheter une mais il ne me faudrait ne pas retomber dans les mêmes problèmes ...

xubu1957

~~Tester un noyau 5.8 hwe-edge ?~~ Ou tester la version 20.04 ?

merci à toi pour toutes ces infos.

je reprends demain...

LaurentDelaon

Je pense avoir du nouveau:

 dmesg | grep firmware

apparemment il n'a pas eu assez à manger...

Après cela semble logique de ne pas voir wlan0.

Bonjour,

Je vois dans > forum.endeavouros.com/t/iwlwifi-issue

Le 20/06/2020, onyxnz a écritAfter trying 5.6.14 and 15, and getting the same result, I wondered about the kernel parameters sent by grub, as they were not active with the MXLinux.
On this laptop I had found that the parameters : quiet irqpoll loglevel=3 pci=nomsi,noaer
had to be passed in order for the hardware to be happy. At a guess, I removed the pci=nomsi,noaer
and found that booting now dmesg | grep iwl gave a vastly different result, and no lockups;

Après avoir essayé 5.6.14 et 15, et obtenu le même résultat, je me suis interrogé sur les paramètres du noyau envoyés par grub, car ils n'étaient pas actifs avec le MXLinux.
Sur ce portable, j'avais trouvé les paramètres : quiet irqpoll loglevel=3 pci=nomsi,noaer
pour que le matériel fonctionne. Au hasard, j'ai enlevé le pci=nomsi,noaer
et a constaté que le fait de démarrer maintenant dmesg | grep iwl donnait un résultat très différent, et pas de blocage ;

Mais moi et les paramètres du noyau ! 🙁

bonjour

j'ai installé une clé usb wifi tp-link TL-WN725N.
Je pense (?) quelle est bien installée.
