wifi très lent voir inopérant lubuntu 14.04

Holmung · Le 14/05/2014, à 20:09

Bonjour,

j'ai un petit problème avec mon ordinateur, j'ai installé depuis peu lubuntu 14.04 (il est plutôt ancien) et l'adaptateur wifi usb fonctionne très mal. Le débit est quasi nul. Il s'agit d'un asus wl-167g

Quelqu'un aurait-il une solution?

Merci et bonne soirée à vous
