设备未准备好(固件缺失)

设备未准备好(固件缺失)

我在网络菜单中使用 Ubuntu 16.04 LTS,显示:

设备未准备好(缺少固件)。

请帮助我使我的电脑的无线适配器正常工作。

当我运行时lspci -v它显示

  • 安装固件包

    sudo apt-get update
    sudo apt-get install linux-firmware
    

    然后重新启动,看看是否有效。

  • 如果不起作用,请将rt2800pci模块列入黑名单

    echo "blacklist rt2800pci" | sudo tee /etc/modprobe.d/blacklist-myrt2800pci.conf
    

    然后重新启动。
