# `0bda:0811 Realtek Semiconductor Corp.` USB无线网卡Linux驱动

针对 Ubuntu 18.04(LTS) 的安装,亲测可用,在此贡献出来。

0. 安装`dkms`、`linux-headers`:

```
$sudo apt update
$sudo apt full-upgrade
$sudo apt install dkms linux-headers-$(unmae -r)
```

1. `git clone git@github.com:gnu4cn/rtl8812au`

2. `cd rtl8812au`

3. `sudo ./dkms-install.sh`

4. `reboot`

# RTL8811AU无线网卡linux驱动安装笔记(Fedora、Ubuntu)

最近公司重新布网络,采购了一批无线网卡都是是USB接口的,卡王(Card-king)KW-AC8012 600M双频增强型外置天线USB无线网卡([https://item.jd.com/7216632.html](https://item.jd.com/7216632.html)),芯片型号是Realtek RTL8811AU的。这款无线网卡要是放在Windows环境下的话,即插即用,不用安装驱动。但是Linux就悲剧了,只能自己编译安装驱动。

USB网卡自带了一张光盘,光盘里有Linux下的驱动源码,还有安装脚本。但经过尝试,可能是因为编译器版本问题,无法编译出驱动文件,只能再想其他办法。

于是网上找了不少第三方的驱动,但无一例外,编译失败或者是无法驱动。最后找到了几篇比较有参考意义的文章,折腾了一下,重要可以用了。参考文章如下:

参考1:[https://blog.csdn.net/jerry_sc/article/details/76407673](https://blog.csdn.net/jerry_sc/article/details/76407673)

参考2:[https://dustymabe.com/2016/01/24/802.11ac-on-linux-with-netgear-a6100-rtl8811au-usb-adapter/](https://dustymabe.com/2016/01/24/802.11ac-on-linux-with-netgear-a6100-rtl8811au-usb-adapter/)

我的编译、安装步骤主要参考 [https://blog.csdn.net/jerry_sc/article/details/76407673](https://blog.csdn.net/jerry_sc/article/details/76407673),并做部分修改。

1. 首先,升级系统,安装内核头文件

Ubuntu下命令行如下(我用的Elementary,基于Ubuntu,所以操作一样):

```
$ sudo -i
# apt-get update
# apt-get upgrade
# apt-get install dkms linux-headers-$(uname -r)
```

Fedora下相应的命令是:

```
# dnf install -y dkms kernel-devel-$(uname -r)
# systemctl enable dkms
```

2. 去GitHub下载驱动源码。下载 [https://github.com/paspro/rtl8812au](https://github.com/paspro/rtl8812au) (已失效)提供的源码 `v5.1.5` 版本,只有这个版本亲测可用,其他版本都有问题!!!你可以安装 `git` 命令,也可以在网页上下载,都行。虽然源码显示的是 `RTL8812AU` 型号无线网卡的驱动,但 `RTL8811AU` 也一样可以用。CSDN 上我也放了一份: [https://download.csdn.net/download/zzzzllll2006/10625455](https://download.csdn.net/download/zzzzllll2006/10625455)。

3. 编译安装驱动。下载下来的源码里有个文件 `dkms-install.sh`,本以为直接执行脚本,就完成了,可是却出现了多个奇怪的错误,仔细检查发现,原来是脚本作者在拷贝驱动源文件的时候写错了路径,修改一下就OK了。

```
cp -r ../${DRV_DIR} /usr/src/${DRV_NAME}-${DRV_VERSION}
```

这一句修改成下面的,这样进入源码目录,`sudo ./dkms-install.sh` 即可。

```
mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
cp -r . /usr/src/${DRV_NAME}-${DRV_VERSION}
```

经过测试,GitHub上的牛人给出的驱动兼容性挺好,Ubuntu、Elementary、Fedora 都可以用,还挺稳定的。

# Realtek RTL8812AU Driver

## DKMS
This driver can be installed using [DKMS](http://linux.dell.com/dkms/). This is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the `dkms` package, which on Debian (based) systems is done like this:
```
sudo apt install dkms
```

## Installation of Driver
In order to install the driver open a terminal in the directory with the source code and execute the following command:
```
sudo ./dkms-install.sh
```

## Removal of Driver
In order to remove the driver from your system open a terminal in the directory with the source code and execute the following command:
```
sudo ./dkms-remove.sh
```

## Note
For Ubuntu 17.04 add the following lines
```
[device]
wifi.scan-rand-mac-address=no
```
at the end of file /etc/NetworkManager/NetworkManager.conf and restart NetworkManager with the command:
```
sudo service NetworkManager restart
```
