Depuis la version 22 connexion défaillante

Bonjour,

Depuis que je suis passée à la version 22 ma connexion wifi est très lente à se faire. Quelle peut bien en être la raison ?

Merci à vous

Re : Depuis la version 22 connexion défaillante

OK, verrai ça après la fin de session de travail : un peu peur de trifouiller la connexion et de la perdre du coup...

Petite question en attendant, pourquoi j'ai deux noms dont un avec 5ghz à ma connexion ? Il faut se connecter de préférence à l'une des deux instances ?

Tu as une carte wifi qui gère les fréquences 2.4 et 5 GHz.

or la connexion est à nouveau super lente à se faire. Nota bene : me suis rendu compte que parfois mettre en route le VPN la faisait se mettre en route, ou bien est-ce une coïncidence (mais ça a "marché" à plusieurs reprises)...
