[WIFI] wlan0 qui déconnecte

Support Debian
#1

Bonjour a tous,
Je vous écrit suite a un problème que je rencontre sur ma Debian 8 fraîchement installée.

En effet ma connexion internet passe son temps a planter (uniquement en wifi).
Lorsque je boot aucun problème, le wlan0 est bien connecté, je peux pinguer et accéder au web sans soucis, cependant au bout d’un temps (des fois 30min, des fois 2min) je me retrouve avec 2 ipv6 et plus de connexion.

Si je coupe les connexion réseau et le network manager je me retrouve des fois avec aucune adresse ip des fois avec seulement les deux ipv6.

Quand je retente de me connecter je n’ai pas de connexion réseau alors que quand je regarde les logs je suis sensé être connecté.

J’ai également testé avec wicd a la place du network-manager mais rien n’y fait, la seule solution qui marche est de reboot.
Quand je reboot tout refonctionne pour un certain temps puis replante, et plus je reboot moins longtemps le réseau tiens avant de planter.

Sur mon windows je n’ai absolument pas de problème et je retrouve ce problème sur mon Kali.
Je commence vraiment a sécher et a plus trop avoir d’idées.

En espérant qu’une ame charitable vienne me filer un petit coup de main :wink:

#2

Je n’ai pas compris le rapport avec l’IPv6.

#3

Je parle d’ipv6 parce que j’ai 2 adresses ipv6 lorsque ça bug et que ça me semble bizarre.
Après je sais pas si ça a vraiment quelque chose a voir mais je n’ai jamais eu de ifconfig de ce genre donc je précise au cas ou.

#4

Et tu ne les as pas quand ça marche ? Ou bien tu ne regardes que quand ça ne marche plus ?

#5

Quand je viens de booter j’ai juste une ipv6 mais l’autre apparaît seule des fois.

#6

C’est ce que je voulais te faire comprendre. L’IPv6 n’a rien à voir avec ton problème.

#7

Mais du coup pourquoi j’en ai deux? J’ai jamais vu ça encore.
Du coup je change le titre du post?

#8

C’est pourtant la norme.
Celle qui commence par fe80 est dite “link local”, elle est configurée automatiquement dès que l’interface est opérationnelle et ne sert que pour des opérations de bas niveau comme la résolution d’adresse IPv6 (l’équivalent d’ARP) ou la communication avec le routeur.
L’autre est configurée automatiquement suite à la réception d’une annonce de routeur IPv6, émise vraisemblablement par la box. C’est une sorte de DHCP simplifié. C’est avec cette adresse dite “globale” que la machine peut communiquer en IPv6 avec le reste du monde.

Je pense que oui, tu peux modifier le titre.

Tu peux aussi exposer les différences concrètes entre le moment où ça marche et le moment où ça ne marche pas résultant de tests simples comme :

  • la sortie de ifconfig wlan0et iwconfig wlan0 (pas besoin des autres interfaces - installer wireless-tools si pas présent)
  • résultat de ping/traceroute par nom et adresse IP
  • table de routage affichée par ip route
  • derniers messages du noyau affichés par dmesg
#9

Ok je vais jeter un œil a ça quand ça replantera (comme par hasard je poste et le wifi ne plante plus)

#10

Du coup j’ai tout regardé mais aucune config ne change dans le ifconfig ou iwconfig, pas de nouveaux messages avec un dmesg | tail entre le moment ou ça marche et ou ça plante.

Quand je ping ou traceroute par nom impossible de résoudre l’IP et quand je ping par IP impossible d’atteindre l’hébergeur.

Voila quelques résultats.

Si tu a besoin des retours pour quand ça marche je les ais sous la main

Peux-tu confirmer le résultat du ping 8.8.8.8, cela ne me semble pas cohérent ?

#12

Effectivement je me suis trompé de retour comme un boulet.

Salut
Les déconnexions wifi c’est souvent à cause du power management
As-tu essayé ?

sudo iwconfig wlan0 power off

#14

Le power management est déjà en off

#15

L’erreur “Destination Host Unreachable” de ping ou “!H” de traceroute émise par la machine elle-même indique que la résolution ARP de l’adresse du premier saut (le routeur) a échoué. C’est cohérent avec une perte de connectivité au niveau de la liaison. Le problème peut se situer au niveau du pilote de Linux pour cette interface wifi.

#16

Quels sont la carte et le driver pour le Network controller?

lspci -nnk | grep -i net -A2
#17

Salut,
Alors ma carte est une Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC.

Voila le retour de la commande lspci -nnk | grep -i net -A2

02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 10) Subsystem: ASUSTeK Computer Inc. Device [1043:200f] Kernel driver in use: r8169 03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] Subsystem: Lite-On Communications Inc Device [11ad:1724] Kernel driver in use: rtl8723be

Basiquement la carte wifi est pas fonctionnelle mais en installant rtlwifi depuis les dépôts non-free ça passe tout seul. J’avais exactement le même problème avec mon ancien Asus mais une fois le driver installé j’ai jamais eu de soucis.

#18

la fameuse carte qui merdouille toujours sous Linux
jette un oeil la dessus:

#19

Super !!!
C’était exactement ce dont j’avais besoin \o/
Merci beaucoup.
Je passe en résolu.
