[résolu] Problème d'accès à certain sites

Bonjour

J'ai depuis longtemps un Pc sous Linux 16-04 qui fonctionne très bien en wifi. Depuis quelques jours, je ne peux plus accéder qu'à certains sites (google, korben.info, ...) alors que d'autres donne une erreur : vous n’êtes pas connecté à internet (lemonde.fr, ubuntu-fr.org, accès imap, accès dropbox, ...).

Ce site est inaccessible

http://www.voilesetvoiliers.com/ est inaccessible.
Effectuez une recherche Google sur voilesetvoiliers.
ERR_ADDRESS_UNREACHABLE

et ce avec Chrome ou Firefox. L'accès à internet avec une connexion filaire ethernet fonctionne très bien.
Le seul événement entre avant et après : je me suis connecté en Wifi via mon mobile mis en mode modem !!!

J'ai fait quelques recherches dans les différents forum, je n'ai pas trouvé de réponse.

Merci de votre aide.

Re : [résolu] Problème d'accès à certain sites

Bonsoir

Si je comprends bien tu accèdes à l'internet par la 4G de ton mobile. La première explication qui vient à l'esprit est l'interdiction qui te serait opposée par ton opérateur mobile d'accéder à certains sites. Le problème ne provient certainement pas de ta configuration.

Re : [résolu] Problème d'accès à certain sites

Bonsoir

J'ai été pas clair :
J'accèdais avec le Wifi de ma livebox, ça fonctionnait très bien
Je fais une connexion avec le wifi de mon mobile 4G, ça fonctionne très bien. Et je l'ai fait plusieurs fois
Depuis peu, ma connexion avec le wifi de la livebox ne fonctionne plus pour la plupart des sites.

Les autres ordinateurs de la maison (aussi sous linux) fonctionnent normalement.
Le seul fait que j'ai trouvé est que j'ai utilisé le wifi de mon mobile entre le moment où ça marchait et après. Mais il n'y a peut être pas de corrélation.

Merci de votre aide.

Re : [résolu] Problème d'accès à certain sites

Salut,

ta connexion via le mobile a peut-être mis la zone au niveau des DNS
donne le retour stp de

nmcli dev show |grep DNS

ainsi que

 nslookup lemonde.fr

compare avec les autres PC linux reliés à la même box.

Re : [résolu] Problème d'accès à certain sites

Le PC qui fonctionne en wifi a ça en plus

nmcli dev show |grep DNS
IP4.DNS[1]:    192.168.1.1

l'adresse de la livebox en IPV4.

je propose 2 solutions :
Supprimer la connexion wifi à la livebox (via network manager) et la recréer
ou alors voir du coté de network manager et la partie dhcp IPV4:
tu as quoi dans cette fenêtre ?

Re : [résolu] Problème d'accès à certain sites

Bonsoir à tous

Mystérieusement, ça remarche ce soir en rallumant mon ordinateur. Je l'avais pourtant fait plusieurs fois...

Le DNS en mode wifi s'est transformé tout seul en :

nmcli dev show |grep DNS
IP4.DNS[1]:                             192.168.1.1
IP6.DNS[1]:                             fe80::f282:61ff:feca:ebe2

Merci de votre soutien.
