[Résolu] Débit wifi faible
Bonjour,
Depuis que j'ai intallé ubuntu j'ai l'impression que mon débit est faible. Avant je téléchargeais à environ 500 Ko/s mais sous Ubuntu c'est plutôt du 100 Ko/s grand max.
J'ai bien essayé différentes manip trouvé sur le forum mais rien de flagrant niveau changement.
