Bonjour,
J'ai un HP EliteBook sous Ubuntu 18.04, et comme dit dans le titre, et depuis une mise à jour automatique cette semaine, le wifi a énormément ralenti. Les pings sont très mauvais (en moyenne plus de 200ms pour des sites tels que yahoo ou google). La connexion wifi au démarrage est très lente à se faire, et l'icône de connexion wifi met plusieurs minutes à apparaître.
Voici le résultat de Wikicheck :
