Yoga 11s wifi 卡驱动程序未预装。我已按照网上的许多说明操作，所有说明都包括下载相同的软件包、解压缩、制作、sudo make install。总结如下这里。我使用过的这种方法的每种变体都因相同的两个错误而失败。当我尝试“制作”代码时，会出现两个“没有这样的文件或目录”错误。我已检查以确保我的内核头文件已安装，因为有人说默认情况下没有安装。我认为那个人错了。@chili555 请求 lspci -nn、grep 0280、lsb_release -d。它们按此顺序排列。
lspci-nn：

grep 0280 删除了目录和我的用户名，但没有其他内容。我可以输入并按回车键，但据我所知，它什么也没做。
lsb_release -d 给出输出：

答案1
这是您的设备：
ID 0bda:1724 瑞昱半导体公司
它由驱动程序 8723au 覆盖，必须从源代码编译。首先，验证您是否已安装先决条件：
sudo apt-get install build-essential linux-headers-generic
在继续之前，您需要验证两者是否都已安装。如果已安装，请下载此文件并将其移动到您的桌面：https://github.com/lwfinger/rtl8723au/archive/kernel_version.zip右键单击它并选择“在此处提取”。现在，在终端中：
cd ~/Desktop/rtl8723au-kernel-version
make
sudo make install
sudo modprobe 8723au
请发布任何错误或其他问题。我会再次进行编辑。
