Netbook Toshiba NB200-10Z WIFI instable ?
Bonjour !
Je suis récemment passer chez Ubuntu Netbook Remix 9.10 sur mon netbook.
Cependant comme j'ai de nombreuses déconnections intempestives et cela sur plusieurs HotSpot (Un hotspot NeufWifi et sur mon Wifi domestique Freebox V4) je me demande s'il n'y a pas des problèmes avec les drivers de ma carte wifi.
Voici donc les pré-requis dans le cadre du wifi Freebox :

Re : Netbook Toshiba NB200-10Z WIFI instable ?
Bon j'ai re-installer entièrement Ubuntu Netbook Remix (pour d'autres raisons...) et le problème persiste.
Une idée ?

Re : Netbook Toshiba NB200-10Z WIFI instable ?
Bonjour,
Tu peux essayer un pilote plus récent avec les backports :
sudo apt-get install linux-backports-modules-karmicMembre de l'April (www.april.org)
Pour éviter de perdre vos données, utilisez des formats ouverts (cf. www.formats-ouverts.org).
Regardez l'utilisation moyenne de votre processeur et pensez à BOINC.

Re : Netbook Toshiba NB200-10Z WIFI instable ?
Bon après une semaine d'utilisation du Wifi... C'est loin d'être résolu en faite.
La je viens de faire la comparaison, je reset l'AP (une freebox en l'occurence). Je me place à coté et test sous Ubuntu le résultat. Réception à 50% a 4m de la freebox, connection completement instable...
Sur windows réception excellente (proche de 100%) et stabilité exemplaire.
J'ai vraiment pas envie de devoir retourner sur windows juste pour une histoire de wifi. Mais bon un netbook sans le net stable... c'est pénible 
A l'aide !!
