Commande PING OK mais internet HSRésolu/Fermé

Question

Bonjour,  



Bonjour à tous, 

Je suis en dual boot Win7 et Ubuntu mais mon problème est que internet ne fonctionne pas sous Ubuntu, cependant un ping www.google.fr fonctionne. 
De plus, le wifi fonctionnait bien un moment puis d'un coup il n'a plus fonctionné, j'ai réinstallé Ubuntu, toujours le même problème désormais. 
Je précise que j'ai bien recherché sur le forum, j'ai trouvé des sujets ressemblant à mon problème mais ils ne l'ont pas solutionné... 

Voici le résultat des commandes dont vous aurez sûrement besoin :

Bonjour,
A mon avis, tu as mis trop d'info...
Lorsque tu fais un ping de www.google.com tu as une réponse correcte.
 - C'est bien ce que tu dis ?

Cela signifie que ta configuration réseau est correcte et que tes dns sont bien configurés.

Fais un ping sur un autre nom de domaine pour vérifier.
Par exemple 
$sudo ping www.commentcamarche.net

Si ça marche aussi, il faudra voir la configuration de ton navigateur...

- Est-ce que sur ton réseau un proxy est configuré ?
Si oui, il faudra que tu l'indiques.


Vu ton IP : inet adr:172.20.10.2  Bcast:172.20.10.15  Masque:255.255.255.240 
A mon avis tu es dans une société, donc tu as peut-être un proxy.

Bien cordialement.

Salut,

Aucun souci au niveau du ping, meme avec un ping commentcamarche.net ou d'autres sites.

Aucun proxy étant donné que je suis chez moi. Cette IP est bizarre car quand j'ai exécuté la commande j'étais connecté en 3G avec l'iPhone.

Merci pour ta réponse.

dubcek · Answer

hello
quel est le message d'erreur du navigateur quand tu ouvres une page ?

Mickou95310 · Answer

J'ai aucun message d'erreur, je vois juste en bas de la page qu'il y a écrit "en attente de google.fr" par exemple.

Bonjour,
Je vais te donner un petit truc à essayer.
Ouvre un terminal et tape exactement ce que j'écris en dessous, à la lettre près :
$ cd /tmp
$ rm index.html
$ wget http://www.monip.org ; grep -i "IP : " index.html | grep -o " [0-9]*\.[0-9]*\.[0-9]*\.[0-9]*"


Explication :
En premier lieu, un fichier index.html va être téléchargé.
Ce fichier index.html contient ton adresse IP publique, la commande grep la recherchera et si ça fonctionne ce sera la dernière ligne qui apparaitra.


Cordialement.

Bonjour à tous,

Je viens de remarquer que lorsque j'ai des déco/reco avec mon wifi sur Ubuntu, j'en ai aussi avec tous mes autres appareils connectés sur mon WiFi comme mon iPhone, mon PC portable...

J'espère que ça pourra vous aider.

A bientôt !

Résolu en changeant la clé compatible seulement avec la norme G, Ubuntu fait la gueule avec la norme N.

Commande PING OK mais internet HS
