一些细节：

tag-icon • tag-icon wireless 14.10 rfkill
一些细节：

我有一台运行 Ubuntu 14.10 的华硕 N550JV。

我已经用 i3 替换了 Unity，从那时起就一直存在网络问题。

现在我的 WIFI 在 i3 加载后立即连接，但 1 秒后断开连接。但与此同时以太网保持连接。

一些细节：

@dev-Laptop:~$ sudo rfkill list all
0: asus-wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
@dev-Laptop:~$ sudo cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
        wpa-ssid ssid
        wpa-psk password

如果我添加rfkill unblock all的/etc/rc.local话，它将根本无法通过任何网络启动，尽管rfkill list all显示一切都已畅通无阻。

在上面的配置中：

@dev-Laptop:~$ sudo ifup wlan0 -v

有什么想法可以从这里开始吗？我在 Google 上搜索了一段时间，并让管理员通过 wpa_cli 建立连接，但无法持续。

该 wifi 采用 WPA/PSK2 保护。

我非常有信心，一旦启动完成，辅助模块asus_nb_wmi加载，它变成离开无线网络；请注意：

2：phy0：无线局域网 软阻止：是 硬阻止：是

让我们尝试一个驱动程序参数。请打开终端并执行：

sudo -i
echo "options asus_nb_wmi wapf=1"  >  /etc/modprobe.d/asus_nb_wmi.conf
modprobe -r asus_nb_wmi
modprobe asus_nb_wmi
exit

可能需要重新启动。有什么改善吗？如果没有，请重复上述顺序，但使用 4 代替 1：

sudo -i
echo "options asus_nb_wmi wapf=4"  >  /etc/modprobe.d/asus_nb_wmi.conf
modprobe -r asus_nb_wmi
modprobe asus_nb_wmi
exit
