Bonjour,
Quand j’ouvre ma session, le WiFi se connecte à mon SSID par défaut sans problème et parfois, tout se passe bien.
Mais parfois, je n’ai plus aucun réseau.
Est-ce que vous voyez comment je peux le relancer sans avoir à redémarrer le PC ? Ou encore mieux, comment corriger ce problème (qui dure depuis quelques mois mais pas eu le temps de me pencher dessus) ?
Je vous mets quelques retours de commande (je suis en partage de connexion avec mon téléphone car je n’ai plus de réseau sans fil sur le PC).
