腾达USB无线网卡（U12）驱动安装笔记

作者：互联网

在京东上给家里的台式机(DELL OPTIPLEX 380)买了一个USB无线网卡（U12），腾达官方的驱动无法使用，因为其支持的Linux内核最大版本为4.4。本文介绍如何在Ubuntu16.04上安装这一网卡驱动。

00 - 系统信息

$ cat /etc/*release | grep VERSION=
VERSION="16.04.6 LTS (Xenial Xerus)"

$ uname -r
4.15.0-88-generic

01 - 尝试编译腾达官方的驱动

$ wget https://down.tenda.com.cn/uploadfile/U12/U12_linux_v5.1.5_19247_Driver.zip
$ unzip U12_linux_v5.1.5_19247_Driver.zip

尝试修改了一些编译错误，但是又蹦出新的错误，果断放弃这一思路！

02 - 搜索现成的解决方案

找到了一个GitHub的repo, Realtek 802.11n WLAN Adapter Linux driver! 果然有人做了对应的修复，那就直接拿来用吧。

$ git clone https://github.com/gnab/rtl8812au.git
$ cd rtl8812au/
$ make
$ sudo make install

$ # NOTE: rt8812au.ko is installed to /lib/modules/4.15.0-88-generic/kernel/drivers/net/wireless/8812au.ko

$ sudo modprobe 8812au
$ sudo lsmod | egrep 8812au
    8812au                856064  0

连接wifi成功上网，网卡状态如下：

$ ethinfo enx502b73d14b1b
ETH             MAC               STATE DEVICEID VENDORID MTU  SPEED BDF     DRIVER                IPv4            
enx502b73d14b1b 50:2b:73:d1:4b:1b up                      1500       1-5:1.0 usb/drivers/rtl8812au 192.168.3.9/24

大功告成！Have  fun:-)
