Then i restart wpa_supplicant and i get back 3 wifi networks. With kernel-3.3.1 i dont remember this ever happened... -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
