[wifi] Problème pour me connecter au wifi

[stephan08]

Bonjour,

J'ai essayé de me connecter au wifi avec menu-config. J'ai choisi mon wifi puis j'ai tapé le mot de passe wifi mais ça n'a pas marché.

J'ai le message d'erreur suivant:

Code : Tout sélectionner

Job for netctl@wlp20s0\x2dtoto.service failed because the control process exited with error code. See "systemctl status "netctl@wlp20s0\\x2dtoto.service"" and "journalctl -xe" for details.

Du coup, en lançant: systemctl status "netctl@wlp20s0\\x2dtoto.service",
j'obtiens:

The interface of network profile 'wlp20s0-toto' is already up

Re,

J'ai finalement résolu mon problème.

Je suis reparti de 0. J'ai supprimé le profil que j'avais crée dans /etc/netctl puis j'en ai recréé un.

J'ai remarqué dans le profil que j'avais copié de l'exemple Interface=wlan0.

Or en lançant:

Code : Tout sélectionner

ip link

J'obtenais:

Code : Tout sélectionner

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp20s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 00:22:fa:0a:bf:f8 brd ff:ff:ff:ff:ff:ff
3: enp14s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:23:5a:02:63:19 brd ff:ff:ff:ff:ff:ff

Mon interface wifi ne s’appelait pas wlan0 mais wlp20s0. En changeant, ce paramètre dans le profil que j'avais crée, le problème s'est résolu.
