自从我卸载了网络管理器 gnome 后，我的 wifi 就无法工作了。

由于我没有网络管理器 GUI，如何在终端上启用我的 wifi。
正在做
ifconfig wlan0 up
返回此错误
SIOCSIFFLAGS: Operation not permitted
当我使用 sudo 时我得到了
SIOCSIFFLAGS: Operation not possible due to RF-kill
正在做
lsmod

我不明白为什么会出现这个错误，我还没有卸载之前运行良好的 WiFi 驱动程序
答案1
因为我们现在知道hp-wmi正在阻止你的无线，让我们将其列入黑名单：
sudo -i
echo "blacklist hp-wmi" >> /etc/modprobe.d/blacklist.conf
exit
一切已准备就绪。
答案2
您可以从互联网的其他来源离线下载一些网络管理器（作为 .deb 文件），然后将其安装在您的 ubuntu 上并从那里开始。最著名的网络管理器是 network-manager 和 wicd。我个人更喜欢 wicd，因为 network-manager 在我的无线芯片组上有很多错误。您可以从那里开始，因为您现在有一个连接管理器。
