升级到 Ubuntu 16.04 后 Centrino Wireless-N 2230 无法工作

我有一台笔记本电脑 HP Pavilion dv6，我将其从 14.04 升级到 16.04，现在 wifi 网络不工作了。

目前无线按钮（F12）亮蓝灯，所以看起来很正常，但我无法启用 wifi，也无法扫描网络。

这与 14.04 曾经配合良好。

我已进行以下检查，但我完全迷失了。

检查连接：

$ nmcli dev
DISPOSITIVO        TIPO      ESTADO         CONEXIÓN           
eth0               ethernet  conectado      Wired connection 1 
58:55:CA:E6:8C:D0  bt        desconectado   --                 
wlan0              wifi      no disponible  --                 
lo                 loopback  sin gestión    --

检查无线适配器是否被识别：

检查无线设备的状态：

$ rfkill list all

    Soft blocked: no
    Hard blocked: no

更新文件 /etc/default/crda 以设置正确的区域代码：

REGDOMAIN=ES

我建议您将辅助模块列入黑名单：

sudo -i
echo "blacklist hp-wmi"  >>  /etc/modprobe.d/blacklist.conf
exit

重新启动并告诉我们结果。
