WiFi pour HP 17-y020ca sous Ubuntu 16.04 toujours désactivé ou "pas prêt"
J'ai récemment acheté un ordinateur portable HP 17-y020ca et installé XUbuntu 16.04. Ce portable est équipé d’une carte sans fil Broadcom Corporation BCM43142.
Cette carte sans fil n'a pas été détectée à l'origine (mais la carte Ethernet a bien fonctionné) et j'ai suivi les instructions à l'adresse suivante:
Est-il possible d'utiliser le wifi Broadcom BCM43142 dans Ubuntu 16.04?
et maintenant la carte semble être généralement détectée, et "Activer le WiFi" est donné comme une option active (non grisée) dans mon menu Réseau de XFCE.
Lorsque je clique sur "Activer le WiFi", ce menu change souvent le statut pour indiquer qu'il est activé via une coche en regard de "Activer le WiFi". Cependant, lorsque cela se produit, l'une des deux choses se produit plus haut dans le menu. Soit il dit:
"Wi-Fi est désactivé" ou "Wi-Fi non prêt"
J'ai couru le script wireless-info.bash et l'inclure ci-dessous.
Je serais vraiment reconnaissant pour toutes les suggestions que n'importe qui pourrait donner. J'apprécie beaucoup votre considération!
Cordialement, Nathaniel Osgood
