Bonjour,
Je viens d'installer Unbutu 16.04 sur le PC Portable de monépouse. J'ai réussi à installer le Firmware de la carte Wifi avec le peu de connaissance Linux que je possède.
Mais je rencontre le problème suivant:
En utilisant le cable Filaire et le navigateur Firefox, je n'est aucun problème pour me connecter à Internet et ouvrir des pages Web.
Le problème se pose avec le Wifi. En utilisant Firefox je ne peux ouvrir aucune page web.
Je teste la conexion avec mon terminal sur l'URL ou l'IP de Google, j'ai le résultat suivant :
syl@syl-HP-Pavilion-dv7-Notebook-PC:~$ ping 209.85.229.94

C'est apparemment OK
syl@syl-HP-Pavilion-dv7-Notebook-PC:~$ ping
www.google.fr
ping: unknown host
www.google.fr
Apparemment cela ne fonctionne Pas.
Selon mon analyse, il semblerait que j'ai un problème de DNS.
Qu'en pensez vous? C'est d'autant plus étonnant qu'en filaire je n'aurait pas de problème de DNS.
Y aurait-il quelqu'un pour m'expliquer ou solutionner mon problème?
Je suis allé sur le forum. J'ai testé avec un autre navigateur (Chrome). J'ai modifié les 3 propositions sur la configuration du serveur Proxy pour accéder à Internet. mais tous ces tests ne fonctionnent toujours.
Je vous joins mon fichier Wificheck.log pour procéder à l'analyse éventuelle.

CORDIALEMENT
SOLUTION TROUVE EN UTILISANT LA DOCUMENTATION DNS
J'ai utilisé l'interface graphique "network manager" et j'ai suivi la procédure rappeler dans la page documentation DNS.
https://doc.ubuntu-fr.org/dns#par_interface_graphique
* Clic droit sur l’icône de NetworkManager puis : cliquez sur Modification des connexions.
* Choisir quelle connexion est à modifier (par câble ou par Wifi), puis cliquer sur Modifier.
* Cliquer sur l'onglet Paramètres IPv4.
* Dans Méthode sélectionner Adresse automatique uniquement (DHCP).
* Dans la case Serveurs DNS, entrer la ou les adresses DNS souhaitées (si plusieurs adresses, mettre une virgule entre chaque adresse).
J'ai rajouté les adresses IP des serveurs DNS public de Google 8.8.8.8 et 8.8.4.4.
* Cliquer sur Enregistrer.
* Si connecté en wi-fi : se déconnecter puis se reconnecter.
Le problème a enfin été résolu.
NB : j'ai quand même contrôlé avec "network manager" les informations que j'avais sur la connexion filaire. Je n'ai vu nulle part les adresses IP de renseignées pour les serveurs DNS public de Google 8.8.8.8 et 8.8.4.4. Et pourtant dans cette configuration cela fonctionne parfaitement.
Cordialement
