Depuis quelques temps (je ne saurais être plus précis), j'ai des soucis avec mon wifi. Quand j'allume mon ordinateur, le comportement est assez aléatoire : parfois il met très longtemps à se connecter, parfois même ça échoue (et dans ce cas, je ne trouve plus mon wifi dans la liste des connexions proposées), à peu près tout le temps, la connexion est également très lente.
J'ai essayé de chercher une solution mais ça n'est pas évident vu mes très faibles connaissances en informatique. J'ai en particulier essayé quelques trucs que j'ai trouvé ici :
https://forum.ubuntu-fr.org/viewtopic.php?id=377104 sans succès (après, je ne saurais dire si ça ne marche pas ou si j'ai juste mal appliqué ce qui y est expliqué).
J'ai aussi vérifié ce qui est mentionné ici :
https://forum.ubuntu-fr.org/viewtopic.php?id=2003167 Ma connexion est bien seulement en WPA2. Pour ce qui est du secure boot, je n'ai pas trouvé la commande dans le bios.
Voici les informations
