J'utilise Wicd en tant que gestionnaire de réseau
La box est une Livebox mini thomson CFA6
La clé wifi usb est une Ovislink Evo-300USB
selon le site du fabricant elle utilise le chipset rt2872sta au sujet duquel existe une doc:
http://doc.ubuntu-fr.org/wifi_chipset_rt2870

Sur le site de Ralink,j'ai trouvé x drivers dont:

file:///home/jean/2009_0521_RT2870_Linux_STA_V2.1.2.0

et


file:///home/jean/2009_0918_RT2860_Linux_STA_v2.2.0.0

le 1er comporte un patch qui semble adapté au noyau:
file:///home/jean/2009_0521_RT2870_Linux_STA_V2.1.2.0/rt2870-2.6.31-compile.patch

Mais je n'arrive pas à le patcher, voir ci dessous:

jean@gerard:~$ cd /home/jean/2009_0521_RT2870_Linux_STA_V2.1.2
jean@gerard:~/2009_0521_RT2870_Linux_STA_V2.1.2.0$ patch -p0 < 2.6.31-compile.patch
bash: 2.6.31-compile.patch: Aucun fichier ou dossier de ce type
jean@gerard:~/2009_0521_RT2870_Linux_STA_V2.1.2.0$ patch -p0 < rt2870-2.6.31-compile.patch
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
