Ubuntu19.10加载Realtek rtl8812AU驱动程序的问题

Question

我有一个华硕USB-a 53纳诺无线适配器，已经停止工作后，最近一次ubuntu软件更新。适配器仍然在其他机器上工作。

我的节目是19.10，-a的输出是：

jon@jon-basemet:~$ uname -a
Linux jon-basemet 5.3.0-26-generic #28-Ubuntu SMP Wed Dec 18 05:37:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

DKMS状况：

sudo dkms status
nvidia, 390.129, 5.3.0-24-generic, x86_64: installed
nvidia, 390.129, 5.3.0-26-generic, x86_64: installed
rtl8812au, 4.2.2, 5.3.0-26-generic, x86_64: installed

我遵循了这两套指令：

sudo apt update
sudo apt install git
git clone https://github.com/gnab/rtl8812au.git
sudo cp -r rtl8812au  /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2

和

sudo apt-get purge rtl8812au-dkms 
sudo apt-get install git
git clone https://github.com/jeremyb31/rtl8812AU.git
sudo dkms add ./rtl8812AU
sudo dkms install rtl8812AU/5

这两种解决方案都不起作用。

运行日志and跟踪并插入Asus天线(没有安装edimax天线)提供以下内容：

Answer 1

我也有同样的问题，但是在内核5.3.0-26-泛型的发行版升级之后。sudo apt install rtl8812au-dkms在新的内核升级之后一直在工作，但现在没有了，所以你不是一个人。

好吧，在搜索之后，这对我来说很管用：

sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install

从这里得到我的答案也许这对Ubuntu19.10内核5.3需要rtl8814au驱动程序有帮助

发帖者还说：

它适用于我的rtl8814au设备，它应该适用于rtl8812au、rtl8814au和rtl8821au设备。由于一些奇怪的原因，司机不想工作，直到第二次重新启动。我也不知道原因

希望能帮上忙。
