[Résolu] Lenteur résolution DNS sur Livebox + Wifi + Ubuntu 13.10

Bonjour à tous,

La résolution DNS en Wifi sur une Livebox est particulièrement lente (env. 10s) voire inopérante. Cela coïncide avec la mise à jour de 13.04 vers 13.10. Ce pb n'apparaît pas avec une autre box SFR que j'utilise régulièrement.

dig www.google.com

; <<>> DiG 9.9.3-rpz2+rl.13214.22-P2-Ubuntu-1:9.9.3.dfsg.P2-4ubuntu1 <<>> www.google.com
;; global options: +cmd
;; connection timed out; no servers could be reached

J'ai configuré ma connexion en DHCP automatique. En spécifiant les DNS Orange dans l'interface des cnnexions réseaux, la résolution DNS fonctionne un temps seulement (10min en moyenne). Dernier point, la résolution DNS est OK avec mon mobile en wifi sur la même Livebox.

Avez-vous une idée de ce qui ne va pas ?

Voici qqs infos supplémentaires :

Re : [Résolu] Lenteur résolution DNS sur Livebox + Wifi + Ubuntu 13.10

@nam1962: Je ne veux pas crier "Victoire" trop tôt, mais tout semble être revenu à la normale depuis l'upgrade du noyau Linux de 3.11 vers 3.12 ;-) Merci nam1962 pour cette réponse express et redoutablement efficace !

J'attends quelques heures avant de marquer le sujet comme "Résolu".
