Réseau wifi devient extremement lent

gueulderack

Bonjour à tous,

Depuis 3 ou 4 semaines, je constate un sérieux probleme de wifi. Tout fonctionne très bien, puis au bout de quelques heures, le réseau wifi devient inaccessible. Je ne perds pas la connexion mais les débits sont de l'ordre de quelques centaines octets/seconde seulement. La seule solution qu'il me reste est le reboot du système. Lorsque je reviens quelques versions de noyaux en arrière, çà ne se produit plus. Quelqu'un a-t-il dejà rencontré le probleme. Et avez-vous une piste pour diagnostiquer plus serieusement le probleme?
Je précise que le probleme ne se produit pas avec une connexion filaire.
Je suis sous fedora 16 64 bits.

Merci beaucoup.

MarbolanGos

Quand le problème commence :

dmesg | tail -10

Ensuite on aimerait plus d'informations... Distance, adaptateur wifi....

Le réseau est un réseau d'entreprise. Les antennes sont directionnelles et sont proches. Mon signal est excellent, même quand çà commence à déconner. Je ne pense pas qu'il soit défaillant étant donné que des dizaines de personnes sont connectés dessus en permanence, et n'ont aucune gène. Ce n'est pas non plus un problème de saturation du réseau, étant donné que çà arrive également quand il n'y a personne ou presque, sur le réseau.
De mon côté, le soucis se produit sur un laptop HP EliteBook 8540p. Je crois me rappeler que la puce réseau est une puce Intel 82577LM, mais je n'en suis pas sûr à 100%.

Merci MarbolanGos, je te publierai les infos que tu demandes, mercredi quand je retournerai travailler 😉

Voici ce que j'obtiens lorsque le reseau plante:

MarbolanGos

C'est normal que le réseau se mette sur la suisse ?

gueulderack

Oui, c'est un reseau suisse.
Tu vois quelque chose de pas normal?

MarbolanGos

Comme ça je ne vois rien de choquant si c'est un réseau suisse.
Par contre qu'est-ce qui est dit avant [ 4363.167034] ?

Peut-être filtrer avec un :

dmesg | grep wlan0

Et :

dmesg | grep 80211

gueulderack

Des que ca replante, je te publie ca.

gueulderack

Bon, ben ca fait 1 jour que ca n'a pas plante. Je reste en surveillance encore tout le weekend, mais ca semble etre mieux. Je n'ai pourtant rien fait.

gueulderack

Ayez, ca a plante ce matin. Alors voici les messages que j'obtiens:

Pour moi il n'y a rien de bizarre... À part qu'il semble se déconnecter parfois mais de retrouver ses petits le plus souvent.
Que contient :

cat /etc/sysconfig/network-scripts/ifcfg-wlan0

Aussi avant plantage :

# ifconfig
# ip addr

Après plantage : les même commandes.

Et quelle est la différence ?

gueulderack

Ben justement, j'en vois pas?

MarbolanGos

Oui je ne vois pas non plus de différence...
Quel environnement de travail (GNOME, KDE...) ?
Essaye d'ajouter dans /etc/sysconfig/network-scripts/ifcfg-wlan0 :

BOOTPROTO="dhcp"

gueulderack

Je suis sous environnement Gnome Shell.
Par contre, avant d'apporter la modif que tu me proposes, peux-tu me dire ce que ca fait?

Merci

MarbolanGos

Normalement ça servira à rien vu que le fichier dira juste à NetworkManager de chercher automatiquement une adresse IP pour se connecter avec la borne wifi. Sans ce paramètre c'est par défaut.
Par contre je ne vois vraiment pas d'où peut venir la déconnexion et on a pas d'informations pour nous aider...

gueulderack

J'ai ajoute la ligne que tu m'as indique, mais ca a replante ce matin. Je crois que je vais devoir vivre avec ca. Ca fait c....
Merci, mais si quelqu'un a d'autres idees, je suis preneur!
