Réseau wifi ne marche plus (ubuntu 18.04)

rohrohh

Bonjour tout le monde,
Depuis quelques semaines, le réseau wifi ne marche plus sur mon ordinateur (il s'est coupé brusquement). Après avoir essayé de nombreuses solutions issues de différents sites, je me tourne vers ce forum. Le réseau ethernet quant à lui fonctionne très bien.
j'ai passé quelques commandes pour essayer de voir où se situe le problème sans trouver d'où vient le problème. Je suis un peu perplexe.
Voici les résultats :
lshw -C network

  *-network

Comme vous pouvez le voir, le réseau sans fil n'apparait pas. Pensez-vous que ma carte wifi soit hs ?
Merci pour vos retours

Après avoir parcouru les règles du forum et avoir vu qu'il fallait taper d'autres commandes en cas de problème de wifi, j'enrichi mon message :

Je ne sais pas si tout ça peut aider, mais merci

Bonjour,

La carte Network controller n’apparaît plus, je trouve comme exemple, une Ralink RT5390R > Problème Internet sur Ubuntu 18.04.

Bonjour, Merci pour votre retour.
En effet, c'est bien la carte wifi de mon ordi (j'ai vérifié en ouvrant la tour). Comment avez-vous su qu'il s'agissait de cette carte ?

xubu1957

J'ai noté en exemple !

Pour ce modèle : https://www.wireless-driver.com/asus-vivobook-s551ln-bluetooth-wireless-drivers/ le fabricant le distribue sous 4 cartes wifi différentes et 3 cartes bluetooth !!

rohrohh

ok, et à votre aivs, pourquoi la carte network controler n'apparait plus, est-ce lié à un problème de driver ?

xubu1957

Panne matérielle ?

Dévissée ? > [Résolu] Plus de WiFi après passage en 16.04

rohrohh

Elle ne bouge pas, je vais l'enlever et la remettre et si cela ne fonctionne pas, j'en commanderai une nouvelle.
Merci pour votre aide en tout cas. Je reviendrai vers cette discussion une fois ces deux solutions testées.
Merci
