[Abandonné] Perte wifi inexpliquée

FalCT60

Bonsoir,

Ma configuration : PC portable Dell 5530 sur station d'accueil, Ubuntu 16.04, j'utilise une station de disques usb 3 pour y stocker mes données.
Depuis le passage de 14.04 à 16.04, j'ai des pertes de wifi que j'ai fini par attribuer à ma station de disques. Sans conviction, je l'admets.
Pourtant, aussi étonnant cela soit-il, mon wifi tombe peu de temps après que cet appareil soit mis sous tension, et revient presqu'aussitôt qu'il a été éteint.
Dans un premier temps, j'ai mis cela sur le compte d'une alimentation déficiente, puis je me suis rendu compte que d'autres appareils proches étaient impactés.
J'ai tout de même un peu de mal à me figurer de quelle manière un équipement externe censé n'émettre aucun signal et connecté en usb peut perturber une carte wifi mini-pci interne.
Sans compter que je n'exclue pas des causes extérieures, comme le relais SFR tout proche, ou encore des voisins avec des box mal configurées... c'est possible ?

Je suis preneur de toute piste / explication de nature à me permettre de résoudre ce problème.

Merci d'avance,

J.-Luc

Encore que je ne comprenne pas trop pourquoi tu me demandes cela, et surtout de quelle manière cela va mettre en évidence une éventuelle perturbation de mon wifi.
De même, le fil du lien que tu m'indiques ne m'est d'aucune utilité : je n'ai aucun problème de lecture de disques, les transferts sont très rapides. Aucun rapport avec le souci décrit dans le fil en question.
À la limite, je m'attendais plus à ce que me soient demandées des informations relatives à ma carte wifi, du genre

Bonsoir,

FalCT60 a écritMa configuration : PC portable Dell 5530 sur station d'accueil, Ubuntu 16.04, j'utilise une station de disques usb 3 pour y stocker mes données.
Depuis le passage de 14.04 à 16.04, j'ai des pertes de wifi que j'ai fini par attribuer à ma station de disques

J'ai cherché à répondre à ton interrogation ! 🙂

Pour ta carte wifi:

Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

D'après le post # 6 de ce fil : forum.ubuntu-fr.org/viewtopic.php?id=1379131,

essaies les commandes données par f.x0 :

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install firmware-b43-installer
sudo modprobe b43

FalCT60

Réponse un peu tardive, il faudrait que je puisse rallonger les jours de 24 ou 48 h... ou trouver le moyen de me cloner. :rolleyes:
Ainsi que je le pensais, ce très vieux sujet n'a pas résolu quoi que ce soit : je perds toujours mon wifi lorsque j'allume ma station de disques.
D'ailleurs, c'est flagrant : ma compagne utilise le wifi sur son smartphone pendant que je parcours le forum à la recherche de substance à assimiler. Tout baigne.
Puis, désirant faire un peu de traitement photographique, je démarre ma station de disques et, pas moins de 30 secondes plus tard, plus de wifi. Ni sur le portable, ni sur le smartphone.
Pratiquement plus un seul SSID détecté sur les 6 ou 7 habituellement présents, hormis un ou deux, et encore, de manière sporadique.
Il me suffit de couper l'alimentation de la station de disques pour que tout rentre dans l'ordre en même pas 20 secondes. Voire 10. Portable et tablette de nouveau sur la vague.
J'avoue ne plus comprendre grand'chose. Je veux bien, à la rigueur, que mon portable soit parasité par ma station de disques qui lui est directement reliée, mais quid du smartphone de ma compagne ?
Plus illogique encore, testé tout-à-l'heure : ma compagne près de la box, dans la pièce de l'autre côté séparée de 6 m et deux murs de 30 cm, moi-même dans la chambre avec mon propre smartphone en plus du portable.
Lorsque j'ai allumé la station de disques, non seulement mon portable et mon smartphone ont perdu le wi-fi, mais également le smartphone de ma compagne, pourtant à moins de 2 m de la box. Le signal a chuté de plus de 40 dB, au point de devenir quasi nul et de se confondre presque avec l'axe des abscisses.
J'aimerais bien avoir une explication sur ce phénomène plus qu'étrange à mes yeux, et surtout que l'on m'éclaire sur la manière d'y remédier.
Merci d'avance,

J.-Luc

Bonsoir,

Il faudra attendre un avis éclairé.
C'est pas l'alimentation qui est détériorée ?

FalCT60

C'est ce que j'ai soupçonné en premier, mais je l'ai remplacée par une autre un peu plus puissante (6,5 A au lieu de 4) et, surtout, parfaitement stable, et ça n'a, hélas ! rien changé.

moko138

1) Indépendamment de la station de disques usb3, je m'interroge sur le mode de fonctionnement de la station d'accueil du Dell 5530.

FalCT60 a écritDepuis le passage de 14.04 à 16.04,
(...)

iwconfig
wlan1

Dans 16.04, la wifi ne devrait plus s'appeler "wlan<N>" (ni l'ethernet "eth<P>").
D'où l'idée que la migration ne s'est pas entièrement bien passée.
Si cette hypothèse est juste, il y a bien un problème informatique à corriger.
- -

Et même en appliquant les règles de 14.04, ne devrait-on pas avoir wlan0 s'il y a une seule carte wifi reconnue ?
À titre informatif, dans ma 14.04,
wlan0 est la carte wifi usb utilisée,
wlan1 est la carte wifi pci inutilisée :

3) Et puisque le problème est reproductible, il serait intéressant de voir juste après la disparition de la wifi :

dmesg | tail -n 60

Merci.

4) L'éclairage de ma cuisine, au moment où le thermostat remet en route le moteur du frigo, baisse et remonte.
De même, en relisant

testé tout-à-l'heure : ma compagne près de la box, dans la pièce de l'autre côté séparée de 6 m et deux murs de 30 cm, moi-même dans la chambre avec mon propre smartphone en plus du portable.
Lorsque j'ai allumé la station de disques, non seulement mon portable et mon smartphone ont perdu le wi-fi, mais également le smartphone de ma compagne, pourtant à moins de 2 m de la box. Le signal a chuté de plus de 40 dB, au point de devenir quasi nul et de se confondre presque avec l'axe des abscisses.

l'dée qui vient est qu'au moment où tu allumes la station de disques, le courant disponible pour ta box baisse et remonte (bien qu'elle soit dans une autre pièce) :

Donc, indépendamment du problème informatique éventuel, il me semble quasi certain qu'il y a de toute façon l'installation électrique à corriger.
En attendant, tu trouveras peut-être un contournement en branchant ta box à une prise - si elle existe - moins liée aux fils qui alimentent ta station de disques.

FalCT60

Bonjour moko138,
Je fournirai les résultats demandés un peu plus tard, là je vais juste répondre à ta dernière remarque.
Outre le fait que l'installation électrique est en parfait état - et pour cause -, cela signifierait en fait que ma petite station de disques écroulerait le courant de tout le quartier.
En effet, si tu relis bien ma prose - qui, je l'accorde, peut s'avérer difficilement digeste - tu verras que je perds tous les wi-fi alentours.
D'ailleurs, j'ai vérifié un peu après mon dernier message, c'est 15 à 18 réseaux wi-fi que je capte en temps normal, et non 6 ou 7.
Enfin, je peux mettre sous tension les deux consoles reliées au secteur sur la même ligne et jouer sans que cela ne provoque quelque altération que ce soit. Sachant qu'à elles deux elles consomment beaucoup plus que ma station de disques.
Par contre, consoles éteintes (et même débranchées), station allumée, plus de wifi.
J'ai lu que l'usb 3 pouvait provoquer des interférences, mais, à ce niveau-là, cela devient inquiétant.
Pour le reste, je suis très attentif à toutes tes remarques et vais m'attacher à te fournir tout ce que tu as demandé.
Ah ! et, dernière chose : depuis, j'ai réinstallé 16.04 en préservant le home qui est sur une partition à part. Mais ça ne s'est pas arrangé côté wi-fi. Hélas !

On dirait que ta carte wifi change de cible ('Wi-Fi Maison' puis '543298').
Là, le remède est simple :
si tu as deux réseaux à disposition, tu en choisis un et un seul ciblé par la connexion automatique de network-manager.
Case à (dé)cocher par un clic sur l'appliquette de réseau dans le tableau de bord
--> "Modification des connexions".

- -

Ton extrait de syslog montre, lui aussi, le flottement entre 'Wi-Fi Maison' et '543298'. Mais, étant de 13 minutes postérieur, il est sans rapport avec la déconnexion de 22h18. Et lui non plus ne montre aucun branchement de la station usb.

/!\ Si tu es amené à chercher de nouveau des infos concomitantes dans des logs différents, il serait préférable que tu prépares les différents
"cat... log ..." dans des onglets différents du terminal et que tu les lances vraiment dans un laps de temps réduit au minimum.

Sinon, il existe bien une astuce pour remonter après coup dans les logs, genre :

cat /var/log/syslog | tail -n 1500 | head -n 12

(qui va citer 12 lignes après être remonté de 1500 lignes)
et idem dans syslog.1,
mais il faut tâtonner fastidieusement pour trouver LA minute pertinente, donc être motivé... 😃 (c'est bien utile après un plantage, pour en identifer la cause).

Mes longues explorations m'ont déjà conduit à cet article, que j'ai dévoré mais qui ne m'a pas permis d'aboutir.

C'est apparemment le moins performant, du moins d'après l'appli android que j'ai trouvée dernièrement

xubu1957 a écritQuel est le matériel utilisé pour distribuer le wifi ?

Une Livebox 3 FR - ED4 Sagem

xubu1957 a écritY a t -il un paramétrage sur la bande des 5 GHz?

Oui : il est paramétré à l'identique du 2,4 GHz.
J'ai tenté de le désactiver, mais ça n'a rien apporté de nouveau.
J'ai également tenté de désactiver le 2,4 et de ne laisser que le 5, mais, du coup, plus de connectivité depuis mon Dell.

Te rappelles-tu la tronche que fait le Coyote lorsqu'il se rend compte que le piège qu'il avait préparé à l'attention du Road-Runner va lui péter à la gueule ?
La meinne ne doit pas être tellement différente depuis mon dernier post.
Car le wi-fi ne tombe plus au moment où j'allume la station, mais lorsque des données transitent (lecture audio, vidéo, retouche photo).
Ce qui explique le décalage entre les deux fichiers.
Du coup, ce soir j'ai ris mes dispositions afin de fournir quelaque chose de plus probant et d'exploitable - enfin, du moins l'espéré-je -, confer plus bas.

Non, il s'agit du même réseau : 543298 est le SSID, et Wi-Fi Maison est le nom de la connexion.
J'ai modifié le SSID pour quelque chose de plus parlant tout-à-l'heure.

Il s'est tout de même écoulé environ 8 min entre la première phase et la dernière, mais j'espère que ce ne sera pas problématique.
De toute façon, je pouvais difficilement faire plus court vu que c'est subordonné au comportement du matériel.

Sinon, il existe bien une astuce pour remonter après coup dans les logs, genre :
cat /var/log/syslog | tail -n 1500 | head -n 12
(qui va citer 12 lignes après être remonté de 1500 lignes)
et idem dans syslog.1,
mais il faut tâtonner fastidieusement pour trouver LA minute pertinente, donc être motivé... 😃 (c'est bien utile après un plantage, pour en identifer la cause).

Pour ne rien te cacher, je n'ai pas cessé de repenser à ton allusion de l'autre jour... et j'avoue que, franchement, je ne parviens pas à comprendre comment un périphérique peut parvenir à écrouler à ce point du wi-fi.
Plus j'y réfléchis, et plus cela me laisse perplexe, et ce d'autant plus que cela altère la réception de tous les équipements alentour.
D'autre part, j'ai trouvé une appli pour android qui analyse les signaux et avec laquelle j'ai un peu exploré mon environnement : je capte, selon les moments, entre 6 et 15 SSID différents, dont certains sur plusieurs bandes simultanément. Par exemple, 3 à 6 bandes sur le 2,4.
Là aussi, je demeure perplexe.
Depuis mon dernier message, en plus d'avoir précédemment réinstallé, j'ai également mis à jour le firmware de mon pc. Je doutais que cela pût avoir une quelconque incidence, je ne me trompais pas.
J'ai, au moins, un matériel plus à jour. C'est déjà ça.
Ma prochaine étape sera, après avoir retrouvé les outils qu'il faut pour le faire, une clé bootable 16.04 - quoique, je peux déjà tester avec ma 14.04, si je ne l'ai pas effacée -.
Voilà, je m'en vais retourner gamberger sur ce problème aussi énigmatique qu’incongru. Et, peut-être aussi, vu l'heure, tenter de récupérer un peu de sommeil.
Une bonne nuit à tou(te)s.

Bonjour !
Pas encore tout lu en détail, mais

0) La 14.04 est plus au point que la 16.04.
Alors, si elle prend en charge ton matos, pourquoi s'en priver ? 🙂
D'ailleurs, toi-même en #1 disais :

Depuis le passage de 14.04 à 16.04, j'ai des pertes de wifi

1) Bravo pour ton utilisation des ">>" et des "echo", qui permet de s'y retrouver dans "qui dit quoi, et quand"! 🙂
Il me semble que nous atteindrons la quasi simultanéité en mettant tout en une seule commande :

echo "dmesg | tail -n 60" > avant; dmesg | tail -n 60 >> avant; echo "*************************" >> avant; echo "cat /var/log/kern.log | tail -n 40" >> avant; cat /var/log/kern.log | tail -n 40 >> avant; echo "*************************" >> avant; echo "cat /var/log/syslog | tail -n 40" >> avant; cat /var/log/syslog | tail -n 40 >> avant

- -
et surtout pour le "juste après l'incident wifi", par :

echo "dmesg | tail -n 60" > apres.txt; dmesg | tail -n 60 >> apres.txt; echo "*************************" >> apres.txt; echo "cat /var/log/kern.log | tail -n 40" >> apres.txt; cat /var/log/kern.log | tail -n 40 >> apres.txt; echo "*************************" >> apres.txt; echo "cat /var/log/syslog | tail -n 40" >> apres.txt; cat /var/log/syslog | tail -n 40 >> apres.txt

2) Si je comprends bien ceci, où j'ai réorganisé les lignes de ton lsusb et

/![/b] le premier qui m'indique comment forcer lsusb à présenter son retour dans l'ordre croissant des (Bus ; Device) aura droit à ma gratitude ! 🙂

il y aurait un hub externe (ou autre accessoire) entre ta station de disques et le pc.
Commence par le virer !
Et ne branche en usb3 que les périphériques qui le nécessitent.

Si le problème persiste après cette suppression, redonne le nouveau "avant" et l'apres.txt.

3)

Non, il s'agit du même réseau : 543298 est le SSID, et Wi-Fi Maison est le nom de la connexion.

À mon avis, c'est source de confusion pour le lecteur. Et peut-être pour le système.
Si tu veux bien, au moins le temps de régler le problème wifi, imposer un même nom aux deux, ce serait bien ! (Et ça diminuerait nos consommations d'Aspirine 🙂)

FalCT60

Bonsoir moko138,

Pour reprendre ta numérotation, mais en ordre inverse :

Je ne me rappelle plus la raison pour laquelle j'avais différencié le nom du réseau de son SSID lorsque j'ai débuté, avec la 12.04... mais c'est vrai que les nommer à l'identique ne mange pas de pain.

Je viens de refaire un lsusb pour vérifier une intuition... qui s'est avérée : le matériel que tu pointes fait partie intégrante de la station de disques.
Il s'agit d'un modèle xiaobi qui comporte 2 emplacements sata ainsi que 3 ports usb 3 dont un pouvant alimenter un smartphone ou tout autre appareil.
J'aurais donc peine à le retirer.
C'est le seul appareil qui est connecté en usb 3, car j'ai besoin d'un peu de rapidité lorsque je transfère mes fichiers.
Il n'est pas exclu que je ne la remplace par un modèle eSATA, si ça peut me permettre de régler ce problème.

Merci pour ton compliment.
Je ne fais que suivre le précepte : «Aide-toi, le Ciel t'aidera !». Sans prétention aucune.

Le passage à la 16.04 a été quasi-imposé par une nouvelle version du logiciel photo que j'utilise, qu'il ne m'était pas possible d'installer sur la 14.04.
J'aurais sans doute mieux fait de creuser un peu plus de ce côté-là, au moins en attendant que la 16.04 soit plus mâture.

Ce week-end, je vais tenter de vérifier une hypothèse qui me tracasse.

Bonne soirée,

L'excellent darktable. Tant que j'étais en 14.04, la version la plus récente refusait de s'installer. J'ai naïvement pensé qu'il serait plus rapide de céder aux avances du gestionnaire de màj qui me susurrait de passer à la 16.04 que de chercher à forcer l'installation.
D'un autre côté, j'avais une chance sur deux de me planter... :/
