[résolu] Plus de wifi avec broadcom 43224

Salut, et merci et à tous ceux et celles qui pourront m'aider à rectifier le tir. Ce problème est récurrent avec mon matériel mais ne m'était plus arrivé depuis deux ans.

Je précise que j'ai un interrupteur wifi et que celui-ci est sur ON. Par contre, le témoin lumineux de la wifi s'est éteint. Le problème est intervenu subitement il y a trois jours.

Bonjour,

Ta carte est doublement désactivée, logiquement et matériellement.

	Hard blocked: yes

Manifestement l'interrupteur wifi est sur off.

Re : [résolu] Plus de wifi avec broadcom 43224

Merci Maxire, en mettant l'interrupteur sur l'autre position:

sudo rfkill list
 
2: dell-wifi: Wireless LAN
	Soft blocked: yes
	Hard blocked: yes
5: phy2: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Donc il me semble que ce n'est pas l'interrupteur. Je me doute pourtant qu'il y a un problème matériel.

Re : [résolu] Plus de wifi avec broadcom 43224

Peut-être que c'est la carte qui a lâché?
Si l'action sur l'interrupteur n'a pas d'effet, je ne vois pas quoi conseiller.

Merci. J'espère quand même que ce n'est pas ça.

Re : [résolu] Plus de wifi avec broadcom 43224

Tu peux essayer:

sudo rfkill unblock wifi

Si cela ne marche pas changer la position de l'interrupteur wifi et recommencer.
