[Résolu] Pas de détection de Wifi après le démarrage, Ubuntu 16.04
Bonjour !
Je viens d'installer Ubuntu Studio 16.04 sur mon ordinateur portable (Asus N55S, carte wifi : Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak], chipset : PCI). J'arrive à me connecter au wifi mais seulement si le wifi est déjà en route lorsque je démarre mon ordinateur. Si j'allume le wifi après mon ordinateur, iil n'apparaît pas dans la liste des réseaux possibles et je suis obligé de redémarrer mon ordinateur. J'ai essayé de désactiver /réactiver le réseau, et là je n'ai carrément plus aucun réseau possibles (alors que je capte habituellement une bonne vingtaine de réseux wifi de mes voisins). Du coup, rien ne marche sauf au démarrage, ce qui veut dire que mon matériel est reconnu... Je mets ci-dessous le résultat des commandes habituelles pour la section wifi :

Salut,
Dans ces cas là essaye de relancer la connexion : sudo service network-manager restart
