Perte sans fil de la capacité d'utilisation de 5 GHz (PCE-AC68)
Adaptateur PCI-E sans fil double bande AC1900 PCE-AC68, Ubuntu 15.10 entièrement mis à jour.
Ceci acheté l'année dernière, installé et utilisant certaines ressources en ligne, a réussi à activer la vitesse 802.11ac (donc ne vous souvenez pas des étapes, mais ce n'était pas compliqué).
Je me connecte à un routeur de 5 GHz et de 2,4 GHz.
A bien fonctionné pendant quelques mois, mais depuis quelque temps déjà, 5 GHz ne figurait plus dans la liste. Je ne peux pas non plus l’ajouter, même en spécifiant manuellement le SSID. Le téléphone et la tablette continuent d’utiliser la fréquence 5 GHz comme avant, de sorte qu’il reste toujours là.
J'ai essayé tous les redémarrages, etc., auxquels je pouvais penser.
Couru le script wireless.txt, et en ce que je peux voir les canaux 5GHz, et quelques informations supplémentaires, bien que je ne puisse pas vraiment interpréter les résultats.
Toute idée de ce que cela pourrait être/aide s'il vous plaît en regardant ma config. :)

J'ai eu le même problème que vous et je viens de le trouver. Le réseau 5Ghz était configuré pour choisir automatiquement le canal. Un jour, il est devenu un canal avec un numéro élevé et ma carte n’était plus en mesure de trouver le réseau.
Il suffit donc de vérifier dans votre routeur si le réseau a un canal avec un nombre élevé et de le remplacer par un autre (maintenant je suis avec le canal 40 et cela fonctionne bien) et vérifiez si vous pouvez maintenant retrouver le réseau.
J'ai également ouvert un rapport de bogue dans la page du paquet bcmwl. Si tel est le problème, cliquez sur le bouton "Ce bogue vous concerne" dans cette page
J'espère vous avoir aidé.
