Problème de connexion internet WiFi et filaire
Bonjour,
Cela faisait environ 1 mois que je n'avais pas allumé mon ordi avec Ubuntu. Est voilà que je me rends compte que je n'arrive plus à accéder à internet, que ce soit en WiFi ou filaire. J'ai exploré plusieurs pistes mais rien ne marche. Une aide serait la bienvenue ! Vous trouverez ci-dessous le résultat de plusieurs commandes que j'ai testé lorsque j'étais en connexion WiFi.

Re : Problème de connexion internet WiFi et filaire
Je n'ai peut-être pas été clair. Le pc trouve bien la connexion, mais impossible d'accéder à un site internet ou de faire un ping.
Les commandes que j'ai écrites correspondent donc bien à ce que j'obtiens avec mon pc sur Ubuntu.
Pour rappel, le retour de nm-tool et sudo rfkill list sont (mais je ne suis pas sûr que ce soit très utile dans mon cas) :

Re : Problème de connexion internet WiFi et filaire
Bonjour,
Aucun ping ne marche ? Par exemple, donne le retour de :
ping 8.8.8.8
Sinon, je vais peut-être dire une connerie, mais je trouve bizarre que le DNS soit une adresse locale (192.168.1.1). D'autres pourront donner leur avis ?

Re : Problème de connexion internet WiFi et filaire
Le ping 8.8.8.8 marche bien.
Tu ne m'as pas donné le retour comme je t'ai demandé...
Donc tu as certainement un problème de DNS. Il faut voir dans tes paramètres de connexion ipv4 comment c'est paramétré : DHCP entièrement automatique, adresses automatiques uniquement (DHCP)... Si c'est la première option, change pour la deuxième et entre à la main les DNS primaire et secondaire de ton FAI (ou utilise OpenDNS par exemple).
Il faut faire la même chose pour les 2 connexions (filaire et wifi).

Re : Problème de connexion internet WiFi et filaire
Pour le ping, voici ce que j'obtiens :
$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8 icmp_seq=1 ttl=55 time=284 ms
64 bytes from 8.8.8.8 icmp_seq=2 ttl=55 time=50.1 ms
64 bytes from 8.8.8.8 icmp_seq=3 ttl=55 time=49.8 ms
...
Sinon j'ai essayé de suivre ton conseil et d'utiliser OpenDNS mais sans succès. J'ai toujours les mêmes soucis, même après avoir rebouté ma machine.
Voici comment j'ai modifié la connexion :
As-tu une idée d'où peut venir le problème ?

Alors là, je sèche, mes connaissances en la matière sont assez réduite, j'espère qu'un costaud va pouvoir t'aider.
