iwconfig m'affiche toujours : Access-Point : Not Associated

[supprimé]

Bonjour à tous!

Voilà, j'utilise habituellement nm-applet pour me connecter et ca marche très bien mai là je voudrais me passer de lui.

Du coup j'essaie d'utiliser iwconfig mais ca ne marche pas vraiment.

Quand je suis connecté avec network manager . Iwconfig me renvoit ca :

wlan1     IEEE 802.11bg  ESSID:"Wanadoo_86f6"  
          Mode:Managed  Frequency:2.457 GHz  Access Point: 00:16:41:4E:EC:96   
          Bit Rate=54 Mb/s   Tx-Power=20 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Power Management:off
          Link Quality=82/100  Signal level:36/100  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Quand je fais :

sudo iwconfig wlan1 key 7F612D217C6ACA9E59E74D5C2D
sudo iwconfig wlan1 ap 00:16:41:4E:EC:96

J'obtiens tout de même ceci :

wlan1     IEEE 802.11bg  ESSID:"Wanadoo_86f6"  
          Mode:Managed  Frequency:2.457 GHz  Access Point: Not-Associated   
          Tx-Power=20 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Merci d'avance pour votre aide 🙂

[supprimé]

Je te conseille de tout faire par la console,c'est plus pratique.

Donc debranche et rebranche ta clé wifi ensuite tape ceci :

sudo iwconfig wlan1 essid "ton essid"
sudo iwconfig wlan1 channel "ton channel" <-- ca c'est si t'es pas en channel auto sur ta box
sudo iwconfig wlan1 key "ta clé wep ou wpa"
sudo ifconfig wlan1 up
sudo dhclient wlan1

Apres tu ping google pour voir si t'es connecté a internet.

ping google.com

[supprimé]

sudo iwconfig wlan1 up
iwconfig: unknown command "up"

Quel devait être l'utilité de cette commande?

Bon sinon ca ne marche toujours pas.

[supprimé]

C'est sudo ifconfig wlan1 up et non pas sudo iwconfig wlan1 up !!

En gros ca active ta carte wifi (:

[supprimé]

Ah ok 🙂

Bon, ca ne marche toujours pas. Je suis toujours en "not associated" :/

Et dhclient ne se finit pas et me renvoit ca :

hmm up?

setesat

J'ai exactement le même problème 🙁 (je comptais ouvrir un autre thread 😃).

J'ai un serveur Apache2, et je voulais me connecter à Internet sans lancer d'interface graphique. Avec KDE le wifi marche nikel.
Cependant si je veux l'activer en console cela me donne le même résultat que aqwzsxedcrfb.

L'erreur vient de dhclient ou avant car si je désactive Network manager et que je relance les commandes de la doc cela marche bien.
J'aimerais bien me passer d'interface graphique. 🙂

[supprimé]

up, je n'ai toujours pas trouvé la solution. 🙁

setesat

J'ai juste trouvé une alternative, il s'agit d'éditer à la main le fichier /etc/network/interfaces .

Si ça peut t'aider. 🙂

ggcom

setesat : si tu pouvais préciser ce que tu as mis dans ton /etc/network/interfaces cela m'aiderait.

Je déterre un peu mais j'ai le même problème en mode graphique aucun problème de connexion mais en ligne de commande : impossible (Access Point: Not-Associated) et DHCP ne voit rien...

Mike11310

J'ai eu ce problème plusieurs fois après rechargement de nouvelles versions. Actuellement je viens de charger une nouvelle version 18.04 sur un multi-boot EFI avec W10 que je n'ai pu 'encore' récupérer?
J'ai longtemps cherché, par les différents TUTO et conseils, de récupérer ma connexion Wifi. Sans succès ??
En dernier recours je me suis souvenu m'être sorti du même problème en réinstallant, a coté, une nouvelle version d'Ubuntu, la 16.04 en l'occurence (en lançant la connexion internet dés l'installation initiale).
ET CA MARCHE!! Même sur la 18.04 précédemment installée en parallèle et qui posait problème (Demande de la clé de connection en boucle), et sans changements aucuns.
Malheureusement je suis incapable d'expliquer pourquoi il faut en arriver a cette solution??
Je joint ici le wifichecg.log de la deuxième version (18.04), corrigé par rapport a la première pour ses différences.
Si quelqu'un veut bien m'expliquer, je l'en remercie.

Bonjour,

Pour le pilote wifi RTL8723BE, on conseille d'habitude, de désactiver le secure-boot et de procéder au réglage de l'antenne, voir les § 2 et § 4 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier

Il faut utiliser:

airmon-ng start wlan0

Le manuel nous dit: It may also be used to go back from monitor mode to managed mode.
Iwconfig ne change pas le mode, du moins pas a ma connaissance.
On a deux mode, moniteur et management
