Impossible de se connecter à des réseaux avec un dongle USB Intel Wireless-N 2230 ou ASUS
Je suis actuellement sous Ubuntu 15.05.
Intel Corporation Centrino Wireless-N 2230:
J'ai un mobo MSI avec Intel Wifi:
~ % lspci | grep Centrino
04:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)
Mais cela ne fonctionne pas sous Ubuntu (fonctionne sous Antergos Live USB). Je ne peux me connecter à aucun réseau.

J'ai essayé options iwlwifi 11n_disable=0/1/8, ne fait rien.

Adaptateur réseau 802.11n USB-N13 d'ASUSTek Computer, Inc.:
J'ai donc acheté un dongle USB ASUS n-13 qui annonce le support Linux (coûtait 40 $). C'est à partir de 2012, alors j'ai pensé qu'il devrait fonctionner avec Ubuntu 2015.

Si quelqu'un sait comment résoudre ces problèmes, aidez-nous.
Merci
En fouillant dans votre fichier journal, je vois deux possibilités.
1) Le routeur n'attribue pas d'adresse IP à Ubuntu. J'ai déjà expérimenté cela auparavant, où cela fonctionne avec une distribution et pas une autre - la même machine. Nous avons fini par attribuer une adresse IP statique qui résolvait le problème.
ou
2) Comme quelqu'un l’a souligné ci-dessus, avez-vous essayé une version live distro du 14.04.3 LTS? Si cela fonctionne (ancien noyau) et qu'Antergos fonctionne (super-nouveau noyau), alors je suppose que le problème pourrait être votre noyau. Encore une fois, ne suggérant pas une réinstallation, je souligne que vous devrez peut-être préciser la cause. C'est comme ça qu'on fait ça.
Mon instinct me dit que la version 15.04 est presque définitive. Testez le 14.04.3 LTS - juste pour le test.
Si cela échoue, mon argent est allumé, vous avez besoin d'un noyau plus récent pour la prise en charge.
Si cela fonctionne, mon argent est sur le noyau de la version 15.04 avec un bogue. La solution consiste à avancer ou reculer avec un autre noyau.
Si aucune de ces méthodes ne fonctionne, je reviens à mon propos concernant votre adresse IP attribuée. Mes deux centimes.
