在 Ubuntu 19.10 中加载 Realtek rtl8812AU 驱动程序的问题

Question

我有一个 Asus USB-AC53 Nano wifi 适配器，它在最近的 ubuntu 软件更新后停止工作。该适配器仍然适用于其他机器。

我在 19.10 并且 uname -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 状态：

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

这些解决方案都没有奏效。

运行 journalctl --follow 并插入华硕天线（未安装 edimax 天线）提供以下信息：

Answer 1

我遇到了同样的问题，但在 kernal 5.3.0-26-generic 上进行发行版升级后。sudo apt install rtl8812au-dkms在新内核升级后一直可以工作，但现在不行了，所以你并不孤单。

好吧，经过一番搜索后，这对我有用：

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它有帮助Need rtl8814au driver for kernel 5.3 on Ubuntu 19.10

发布答案的人也这样说：

它在我的 rtl8814au 设备上适用于我，它应该适用于 rtl8812au、rtl8814au 和 rtl8821au 设备。由于某种奇怪的原因，驱动程序在第二次重新启动之前不想工作。我不知道为什么

希望能帮助到你。
