Wifi encore et toujours

sualtam

Bonjour à tous,
la carte wifi reconnait sans souci les différents réseaux disponibles mais je ne parviens à m'y connecter que rarement et lorsque c'est le cas il arrive que la connection s'interrompe et que je ne parvienne plus à me connecter. J'ai regardé un grand nombre de messages sur ce forum qui me semblaient répondre à mon problème mais je n'ai pas trouvé d'issue.

Je suis sur Ubuntu 16.4 avec un Dell Precision M3800 - Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)

J'ai modifié le fichier /etc/NetworkManager/NetworkManager.conf (device] wifi.scan-rand-mac-address=no)
Désactivé le sécure boot

Sans résultat, si quelqu'un peu me venir en aide...
Merci

Bonjour,

Il faut donner, en se servant du : Retour utilisable de commande, ces informations : Configuration wifi ou un [doc]wificheck[/doc]

Essaye d'installer le pilote wifi :

sudo apt update

sudo apt-get install bcmwl-kernel-source

sualtam

J'ai tenté mais sans résultat, il continue à chercher à se connecter au réseau sans succès.

Tu as un routeur ?

Est-il configuré en chiffrement WPA2 seul ?

Voir au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier

sualtam

Non pas de routeur et ça ne concerne pas un wifi particulier. Pour lors, je tente de me connecter via mon téléphone et la 4G et je n'ai qu'un seul chiffrement WPA2.

xubu1957

Tu as vérifié les paramètres > configurer_de_nouveaux_reseaux_ou_modifier_des_reseaux_existants ?

sualtam

Merci mais je n'ai pas bien saisi ce que je devais modifier dans les réseaux existants :/

xubu1957

Tu as regardé si les informations sont correctes ?

xubu1957

Tu n'as pas un pilote propriétaire proposé ?

Doc > [doc]gestionnaire_de_pilotes_proprietaires[/doc]

sualtam

Le mot de passe est bon d'ailleurs actuellement la connexion est passée.

xubu1957

Tu avais passé :

sudo service network-manager restart

sualtam

Oui à plusieurs reprises. Cependant j'ai l'impression que la connexion est plus stable je vais tenter de voir demain sur d'autres réseaux ce que ça donne. Merci en attendant.

xubu1957

Fais voir :

Bonjour,

Tu peux tenter un canal 1 ou un canal 6 > quel-canal-wi-fi-choisir-pour-optimiser-son-debit

sualtam

J'ai beau creuser je ne vois pas comment changer le canal à partir du partage de connexion wifi du smartphone en 4G. Je n'ai malheureusement pas accès à une box en ce moment. La connexion fonctionne un peu mieux depuis hier mais elle reste un peu instable et lorsque cela fonctionne le pc met du temps à attraper la connexion.

xubu1957

Tu n'as pas accès à une notice de ton smartphone ?

sualtam

Je n'y parviens pas j'attends donc d'être en lien avec une box pour vérifier
