Question

Bonjour, 

Bonjour, j'ai installé ubuntu 10.10 sur mon toshiba l350, avant j'avais le wi-fi mais j'ai du le réinstallé et plus rien , je cherche depuis ce matin et rien n'y fait, le site doc-ubuntu étant défaillant je n'ai pas pu l'utiliser.
Je peux me connecter en filaire mais rien du tout en wi-fi, pouvez-vous m'aider merci.

Ton problème est dû au fait que tu as sûrement eu une mise à jour noyau qui utilise une branche de modules (fichiers .ko) qui ne propose plus celui qui gère ta carte wifi. 

Solution simple : tu démarres simplement avec l'ancien noyau.
Solution plus compliquée, explicitée ci-après : on essaye de faire marcher la carte avec ta version de noyau actuelle.

Pour avoir une carte proche de la tienne ce module devrait s'appeller "rtl8192se.ko" ou nom proche.

Vérifie que si ce module n'existe pas. Reporte-moi le résultat de :

uname -r
find /lib/modules/ | grep 8192 | grep ".ko$"

Jusqu'ici avais-tu dû compiler un module/un driver et/ou à installer un driver via le gestionnaire de périphérique ?

Tu peux également chercher avec apt-file pour voir quel paquet pourrait le founir (et installer ce dernier avec ton gestionnaire de paquets) :

sudo apt-get update
sudo apt-get install aptitude
sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude install apt-file
sudo apt-file update
apt-file search 8192 | grep ".ko$"

(reporte moi le résultat de cette dernière commande).

Si aucun paquet ne fournit le fichier ".ko" qui nous intéresse, essaye de trouver un driver libre à compiler. Ainsi tu pourras utiliser ton noyau actuel.

Pour savoir comment on compile un module, un peu de lecture :

Bonne chance
