perte connexion réseau, suite intervention Orange sur le réseau

bonjour

sans souci avec Kubuntu16.04 (sur un disque externe en USB), j'ai récemment un problème d'accès Internet, Wifi ou filaire, avec une Livebox, suite un souci matériel (appel hotline orange, et intervention de leur part)

avec NetworkManager, je me connecte bien à la box en wifi (OK icône), mais pas d'accès réseau
ping 8.8.8.8 ne marche pas,
j'arrive à me connecter à la box, depuis 192.168.1.1
REM alors que depuis win7, je me connecte bien

je ne trouve pas de config concernant mes interfaces eno1 (filaire) et wlp2s0 (wifi), du genre:
auto eno1
iface eno1 inet dhcp
ou
auto wlp2s0
iface wlp2s0 inet dhcp

je n'ai pas fait de modif, en tout cas volontaire, de la config DEPUIS cette intervention

voici la trace wificheck.log

Connecte toi sur l'interface d'administration de ta box et change moi cela pour
  soit que du wpa1 TKIP,
  soit que du wpa2 AES
(ne pas oublier d'enregistrer les changements sur ta box),
Une fois que ce sera fait, tu ne devrais plus avoir de déconnexions

Re : perte connexion réseau, suite intervention Orange sur le réseau

bonjour,

merci, j'avais testé cette solution mais sans succès
seul WPA1
seul WPA2

le souci n'est pas des pertes du wifi, je n'ai pas d'accès du tout :
je ne me connecte pas à Internet, le ping ne fonctionne qu'en local (192.168.1.1) mais pas en extérieur (autres adresses, par exemple DNS de Google, 8.8.8.8)

j'ai tenté un accès filaire (eno1), mais sans plus de succès, il manque quelque chose dans la conf réseau?

Re : perte connexion réseau, suite intervention Orange sur le réseau

salut,
tu es bien connecté à  la box puisque tu as une @ip
wlp2s0    Link encap:Ethernet  HWaddr a0:a8:cd:ae:71:6c 
          inet adr:192.168.1.10  Bcast:192.168.1.255  Masque:255.255.255.0

peut-être un pb de DNS

que dit

cat /etc/resolv.conf

Re : perte connexion réseau, suite intervention Orange sur le réseau

bonjour
oui, en effet, la connexion est OK
j'ai trouvé l'origine du souci : dû à une erreur de PGL (Peerguardian Linux, pare-feu), qui avait perdu sa blocklist (vide)
en stoppant PGL, et retour arrière sur iptables, ça fonctionne!

merci
