Bonjour à tous, je suis vraiment nouveau dans ce truc Ubuntu. J'utilise maintenant le dernier Ubuntu et Windows sur le même PC. Les connexions sans fil fonctionnent bien sur Windows mais se connectent et se déconnectent sur Ubuntu.
Je suis sur l'ADSL avec un routeur sans fil (Belkin et adaptateur réseau sans fil Belkin).

Nous allons avoir besoin de plus d'informations pour pouvoir vous aider. Comme le type d'adaptateur sans fil que vous utilisez et la version d'Ubuntu que vous utilisez.
------ ESSAI 1: Échec
Une astuce générique consiste à System-> Administration-> Hardware Drivers. Vous devrez peut-être télécharger un pilote. Si votre carte sans fil est répertoriée dans la fenêtre qui s'ouvre, veuillez cliquer sur le bouton pour installer ses pilotes.
Mais avec si peu d'informations, ce n'est qu'un tir aveugle.
------ ESSAI 2: Échec
Merci pour toutes les infos. Belkin est célèbre pour utiliser différents chipsets dans le même produit, le F5D7050 utilise au moins 3 chipsets différents. Quoi qu'il en soit, les noms de fichiers du pilote de la fenêtre sont en or. Votre carte est probablement un rt2500.
Le problème le plus courant avec cette carte est que plusieurs modules (une sorte de pilotes Windows) essaient de l'utiliser, ce qui est conflictuel. Vous devrez faire quelques modifications de fichiers pour le résoudre.
Appuyez sur ALT + F2 ou ouvrez une console. Tapez ou copiez/collez:
gksudo gedit /etc/modprobe.d/blacklist.conf
Maintenant, à la fin du fichier, ajoutez ces deux lignes:
blacklist rt2500usb
blacklist rt2800usb
Et redémarrez, si vous êtes chanceux, cela devrait fonctionner après le redémarrage. Sinon, il existe probablement un autre type de conflit, modifiez à nouveau le fichier, supprimez les lignes, redémarrez, ouvrez une console et tapez:
dmesg | grep rt
Il semble qu'aucun module rt * ne soit chargé. C'est donc mon erreur. Mais si le wifi fonctionne (parfois), il doit charger certains pilotes et les pilotes Windows le font ressembler à un rt2500 ...
----------- ESSAI 3: Jamais testé
Un autre coup. Il y a quelques rapports de déconnexions avec des personnes utilisant des chipsets rt * avec le noyau actuel. Vous pouvez essayer de mettre à jour votre noyau.
Vous devez ajouter ce PPA à vos sources logicielles. Dans la page PPA, vous pouvez trouver des instructions détaillées sur la façon de les ajouter, mais en bref, vous devez ouvrir Système-> Administration-> Sources Sotware, cliquez sur l'onglet "Autres logiciels", cliquez sur ajouter et y écrire ppa : kernel-ppa/ppa.
Ensuite, vous devez installer le noyau mis à jour. La manière la plus simple est d'ouvrir le Centre logiciel Ubuntu, sous obtenir le logiciel, sélectionnez le nouveau PPA et dans le panneau de droite choisissez d'installer le Complete Generic Linux Kernel, si vous en voyez deux, choisissez celui sans pae en son nom.
Redémarrez et espérons que les dieux Linux nous souriront cette fois.
Si vous avez un problème avec le nouveau noyau, vous appuyez sur ESC pendant le démarrage pour un menu qui vous permettra de démarrer à partir de l'ancien.
----------- RÉSOLUTION: OP il suffit de construire un autre adaptateur
Habituellement, la solution la plus simple.
