wifi absent de la liste des wifi mais fonctionne ailleurs

Cywil 23

Bonjour à tous,

Je ne retrouve pas le wifi de chez moi dans la liste des wifi disponibles. Alors que :
- ce même wifi fonctionne sur d'autres machines (d'ailleurs il fonctionnait déjà sur ma machine il y a quelques temps, mais je n'ai aucun idée d'une quelconque manip qui aurait pu être à l'origine de l'arrivée du problème)
- ma machine se connecte très bien sur d'autres wifi...

Pour info, un scan iw dev donne :

Tente la solution proposée par toutafai :

Le 21/01/2014, toutafai a écritA tous ceux qui sont avec de l'ASUS :

Essayer cette modification, facilement "réversible" :
gksudo gedit   /etc/modprobe.d/blacklist.conf
A la fin du fichier, rajouter la ligne suivante :
blacklist asus_nb_wmi
Enregistrer la modification, rebooter et tester si le wifi est ok

PS : Pour annuler la modification, il suffit simplement de supprimer la ligne ajoutée, enregistrer et rebooter

Ton ordi est de quelle année ?

Cywil 23

Bonjour,

Merci pour cette piste.

J'ai modifié le fichier puis rebooté mais le wifi ne se trouve toujours pas dans la liste.

L'ordi est de 2013 environ, c'est un Asus X201E

piolet

si le canal du point d'accés wifi est supérieur à 13 cela peut expliquer son invisibilité.
Peux-tu vérifier le numéro du canal ?

si le canal est automatique un reboot de la box peut expliquer que cela fonctionnait avant.

Cywil 23

Bonjour,

Merci pour cette réponse.

Comment vérifier le numéro de canal ?

Cywil 23

bon, ça marche, il suffisait de redémarrer la box...

Merci Piolet !!

piolet

pour vérifier que cela vient bien du numéro de canal
sudo iwlist channel
tu peux voir si les canaux >13 sont gérés

ensuite intervenir sur le paramétrage de ta box pour enlever automatique et fixer un numéro de canal.

Cywil 23

Apparemment ils sont bien gérés oui :

Mais sinon dans mon message précédent, j'ai bien entendu oublié de remercier xubu1957 également !

Merci à vous deux quoi ;-)

xubu1957

Bonjour,

Comme tu as une carte Broadcom BCM4313, il y avait éventuellement le problème du secure-boot, abordé au § 2 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

Merci. 😉
