Bonjour,
Je crois avoir un problème avec la cate réseau de mon PC: il détecte le wifi de tout le voisinage mais pas le miens. Je précise que j'arrive à me connecter en borne wifi avec mon téléphone.
Comme j'ai installé Kubuntu hier et que ne m'y connais absolument rien j'ai du suivre quelques tutos, donc j'ai installé le paquet "firmware-b43-installer" ma ça n'a rien donné.
Merci à vous d'avance
voici un wificheck:
