Salut à tous,
J'ignore ce qui se passe, et c'est bien la 1ère fois que j'ai un souci de wifi avec ubuntu que j'utilise à 100% depuis 12 ans !
Je pense que c'est dû à une mise à jour récente de ma 20.04, mais j'ignore laquelle car le problème, bien que très gênant, n'est pas binaire ça fonctionne, ça fonctionne pas, mais plutôt ça fonctionne très mal 😉
Mon wifi accroche bien la box, mais je n'ai aucun débit, avec des temps de ping indécents. Insurfable ! En connexion ethernet, aucun problème par contre.
Dans les pilotes additionnels, j'ai bien coché utiliser iwlwifi
Je vois :
