[wifi] carrier lost

rafmav · Message par **rafmav** » mer. 09 mars 2016, 10:31

Bonjour

"carrier lost":

Problèmes de connexion sur la ligne wifi du modem fixe qui jusque là marchait très bien depuis des années avec netctl.
Je n'y comprend rien, d'autant que si je me connecte sur la ligne du smartphone par son point d'accès wifi, ça marche très bien et c'est très stable, excepté la lenteur de la 3G

Ci-dessousi ce que ça m'affiche, désolé, c'est long, mais c'est pour faire remarquer que c'est cyclique: "carrier lost": ça se connecte puis déconnecte et reconnecte... pour quelques secondes.

J'ajoute que je n'utilise pas wifi-menu, ni systemd-networkd; ni network-manager que j'avais désinstallé il y a longtemps, car bien trop "manager" et ça n'a jamais marché avec network-manager, donc désinstallé !

Des pistes ?

PS: le modem marche très bien en wifi avec d'autres appareils (sous windows ou android), et ça marche tout seul en filaire avec le laptop archlinux: il suffit juste de brancher la prisse éthernet... mais ça fait cordon ombilical !

Bonjour,
Travail de sagoin, ne sachant pas où chercher...
Donc j'en suis toujours au même point !

La connection éthernet fonctionne correctement dès le branchement du câble, sans attendre que je fasse quoi que ce soit...
La connection wifi fonctionne en me connectant via smartphone, pas via modem...

J'ajoute quelques éléments: un extrait de "dmesg"

Donc 2 types de messages d'erreur: "denied association (code12)" et "disassociated from AP (Reason: 14)"

Une aide sur les codes de messages d'intégrité:
http://www.aboutcher.co.uk/2012/07/linu ... son-codes/
donc là il s'agirait du code 14 pour le "disassociated" :
14 Message integrity code (MIC) failure

j'ai fait ça, via "wpa_cli":
https://forums.gentoo.org/viewtopic-p-4 ... 1a26026bfd

ça a marché plus plus ou moins au début avec wpa_cli qu'il faut laisser ouvert sans faire "exit" avec un peu moins d'instabilité... et je suis déconnecté et reconnecté en permanence, et j'ignore totalement pourquoi !

Bonjour,
Essaye de changer le niveau de sécurité coté Routeur. Tu as quoi comme possibilité ?

rafmav · Message par **rafmav** » dim. 13 mars 2016, 12:43

Un grand merci: ça marche ! Et efficace en plus !

J'ai, par l'interface graphique :

192.168.10.1
security configuration:
None
WEP
WPA
WPA2
WPA/WPA2+TKIP/AES

J'étais en WPA ; je suis passé sur la dernière ligne: WPA/WPA2+TKIP/AES
A priori ça marche, et même très bien.

Ce que je ne comprend pas: ça fait 1 an que j'étais en WPA sans aucun souci; en fait ça déconne depuis que j'ai un nouveau smartphone, même celui-ci éteint... très bizarre et étonnant.

Aussi, j'ai désactivé avahi et mdns, en ce moment inutiles; j'ignore si ça a un rapport.

PS: Je mets en "résolu" dès que je suis sûr que ça marche sans souci; et peut-être changer le titre ?
