wifi instable rtl8187 toshiba satellite pro L300
Bonjour a tous !
j'ai actuellement un toshiba satellite pro L300 avec wifi integrer sur lequel j'ai une partition ubuntu 9.04 ainsi qu'une partition windows xp service pack 3.
Mon soucis est que depuis pas mal de temps maintenant j'essaie en vain d'avoir une connexion stable a internet depuis ma ubuntu. En effet, mon wifi est parfaitement reconnue puisque apres l'installation il voit bien les differents reseaux auquels je peux me connecter.je me connecte alors sans soucis apres avoir entrer la clé wep lorsque ubuntu me le demande.
Le vrai probleme c'est que ma connection devient quasi nulle au bout d'un certain moment sans pour autant me deconnecter.Or je n'ai pas ce probleme sur windows donc j'en deduis que ce n'est pas un probleme materiel.Les telechargement depuis synaptic deviennent donc extremmement lent puisque je passe de 800 ko/s environ a 3000 o/s.
J'ai tenter de me servir de wicd ou d'autres network manager masi rien n'y fait.
voici maintenant les resultats des commandes qui pourrait vous donnees plus d'information:
