USB AC WiFi Dongle（rtl8812au 驱动程序）在我的嵌入式 PC 上不适用于 linux 18.04

使用UNO1372GH和ASUS USB-AC56R。安装 win10 时使用适配器没有问题，但 Linux 18.04.4 LTS 的驱动程序有问题。

这台电脑没有安全启动（它甚至不是一个选项）。

首先，我从华硕支持网站下载并尝试制作官方驱动程序，但未能制作（似乎是一个常见问题）。

然后我尝试下载abperisamy 驱动程序。这些编译成功，但是当我使用 modprobe 并重新启动时，仍然没有检测到 Wi-Fi 加密狗。

我还尝试了 repo 中的最新版本：sudo apt install rtl8812au-dkms。这也安装得很好，但仍然没有检测到。

检查 dmesg，我得到：

iws-ts-001@iwsts001-UNO-1372G-E3AE:~$ dmesg | grep RTL871X
[  218.658179] RTL871X: module init start

[  221.330130] RTL871X: module init ret=0

使用lshw -c network只返回我的以太网适配器，不iw list返回任何内容。

还试过：

lsmod | grep 8812
8812au               1290240  0
cfg80211              712704  1 8812au

我好像都安装了 rtl8812au
