Eu consigo conectar numa rede wifi normalmente, mas se tento conectar em outro rede ou na mesma, dá erro, e não conecta mais.
Só funciona novamente se eu reiniciar o sistema.

Quando conecto:
# wpa_supplicant -Dwext -iwlan1 -B -c /etc/wpa_supplicant/sap.conf
ioctl[SIOCSIWENCODEEXT]: Invalid argument
root@a13:~# <7>wlan1: authenticate with 00:21:91:33:37:95 (try 1)
<7>wlan1: authenticated
<7>wlan1: associate with 00:21:91:33:37:95 (try 1)
<7>wlan1: RX AssocResp from 00:21:91:33:37:95 (capab=0x431 status=0 aid=2)
<7>wlan1: associated

Quando tento conectar em outra rede:
# wpa_supplicant -Dwext -iwlan1 -B -c /etc/wpa_supplicant/home.conf
<7>wlan1: deauthenticating from 00:21:91:33:37:95 by local choice (reason=3)
