高通 Atheros AR9462 与 Ubuntu 18.10

我无法启用 Wifi（按下启用按钮时没有任何反应）并且在 Wifi 设置中显示：

“未找到 Wi-Fi 适配器”

我尝试了其他问题/答案中的几种方法，但都不起作用。以下是一些信息，希望这对答案有帮助：

答案1

您的无线适配器已被阻止rfkill。

您可以通过运行来修复它

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"

重新启动以应用。

您随时可以通过以下方式恢复此黑名单：

sudo rm /etc/modprobe.d/blacklist-ideapad.conf
