断电后没有 D-Link wifi

当我尝试使用 chili555 的神奇重载功能（之前曾奏效）时，我的 Dlink 加密狗失去了 wifi 连接，例如：

cd rtl8812AU_8821AU_linux
make clean
make ( **It messes up here** )

$ make
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.4.0-116-generic/build M=/home/joanne/rtl8812AU_8821AU_linux  modules
make[1]: *** /lib/modules/4.4.0-116-generic/build: No such file or directory.  Stop.
Makefile:1049: recipe for target 'modules' failed
make: *** [modules] Error 2

以下是一些查询结果：

我完全不知道该如何继续下去。

您在编译驱动程序时似乎遇到了麻烦？请尝试以下步骤：

将档案下载到临时目录。

# mkdir -p /tmp/t4u
# cd /tmp/t4u
# wget https://github.com/abperiasamy/rtl8812AU_8821AU_linux/archive/master.zip

解压缩

# unzip master.zip
# cd rtl8812AU_8821AU_linux-master

安装内核头文件

# sudo apt install linux-headers-$(uname -r)

从源代码编译并安装

# make
# sudo make install

加载模块

# sudo modprobe -a rtl8812au

此过程在 GitHub >>> 上有概述https://github.com/abperiasamy/rtl8812AU_8821AU_linux
