Bonjour à tous,
Je fais de nouveau face à un problème avec ma carte Wifi sur la dernière version d'Ubuntu. Après un problème résolu sur ce topic
https://forum.ubuntu-fr.org/viewtopic.php?id=2052337 grâce à l'aide de xubu1957, le wifi n'est plus reconnu du jour au lendemain à la fois par Windows et par Ubuntu... Ma dernière mise à jour d'Ubuntu remonte à au moins une semaine et je n'avais pas de problèmes jusqu'à hier.
Voici le résultat de certaines commandes et on constate des message d'erreurs autour du module iwlwifi :

A noter que j'ai tenté d'effectuer certaines opérations pour résoudre le problème. En effet, avant avec sudo dkms status j'obtenais un WARNING! Diff between built and installed module! autour des modules backport-iwlwifi.
J'ai donc comme suggéré ici
https://forum.ubuntu-fr.org/viewtopic.php?id=2052337 et ici
https://askubuntu.com/questions/1202366/intel-wireless-9650-unclaimed-network?noredirect=1&lq=1 effectué un sudo dkms remove backport-iwlwifi/8324 --all et reboot. J'ai l'impression que le problème serait dû à un conflit entre la version du module que j'utilisais et une nouvelle version mais je ne suis pas du tout un expert. J'ai egalement tenté un sudo modprobe iwlwifi sans succès.
Je suis ouvert à toutes vos suggestions !!
Merci d'avance pour vos réponses !
