按照网络上的说明进行修改后 wifi找不到模块 具体命令如下
sudo apt-get install git build-essential linux-headers-$(uname -r)
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

xxxr 写了:modprobe: ERROR: could not insert 'rtl8821ae': Required key not available
尝试在 BIOS 设置中关闭 “Secure Boot” 功能
如果您安装了双系统,而另一个操作系统要求启用 “Secure Boot”,您可以参考这篇文章
xxxr 写了:-rw-r--r-- 1 root root 456008 12月 6 19:22 /lib/modules/4.13.0-18-generic/.../rtl8821ae.ko
-rw-r--r-- 1 root root 118094 11月 22 00:52 /lib/modules/4.13.0-18-generic/.../r8169.ko
您已经编译了 rtl8821ae.ko 模块并替换了内核自带模块。
