 |
|
Bonjour à tous.
J'ai récemment acheté une carte sans-fil USB (DWA-125) la connexion est très très lente (~5KB/sec).
La seul solution que j'ai trouvé sur Google est de fermer le powersaving (iwconfig wlan0 power off). Cependant, cela
n'a rien changé pour moi.
Voici de l'information sur ma machine qui pourrait être utile:
| Code: |
localhost# uname -a
Linux localhost 3.2.1-gentoo-r2 #2 SMP Sun Feb 26 20:44:15 EST 2012 x86_64 Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz GenuineIntel GNU/Linux
|
Lorsque je ping mon routeur:
| Code: | localhost# ping 192.168.20.1
PING 192.168.20.1 (192.168.20.1) 56(84) bytes of data.
64 bytes from 192.168.20.1: icmp_req=3 ttl=64 time=4.34 ms

Et ma connexion au routeur:
| Code: |
localhost# iwconfig wlan0

Lorsque j'ai fait configuré mon kernel j'ai remarqué que le module rt2800usb est encore expérimental;
C'est peut-être ça qui cause le problème.
Merci en avance

Salut, pourrais-tu essayer avec les derniers git-sources ?
Ça va peut-être t'aider 
Content de voir une personne du Québec. |

J'ai installé le kernel git-sources (3.3.0-rc5) et la connexion semble déjà mieux. Au lieu de 5KB/Sec, j'ai une vitesse de 150KB.
Merci  |
