Ubuntu 12.04.5安装TL-WN725N 2.0无线网卡驱动

实验室有线网络用不了。新配的台式机昨天刚到手。为了让该台式机能用上实验室的无线网络,只好新买了个TP-LINK无线USB网卡。按自带的说明书和提供的网卡,Win7下很简单。但我还装了Ubuntu,考虑不周,该网卡居然没提供Linux驱动。各种Google后终于找到解决方案,希望为后来人提供一点线索,少走弯路。


系统环境:Ubuntu 12.04.5 64位

系统内核:Linux kernel 3.13.0-32-generic


确认无线网卡型号:TL-WN725N 2.0。这商品包装上的图片型号和实物不太一样,估计驱动也就大同小异!

驱动安装步骤:

1) 查看硬件型号。开始在 http://wiki.ubuntu.org.cn/UbuntuHelp:WifiDocs/Driver/bcm43xx 看了,不太明白它分的2类似乎与我的型号都无关。因为我的无线网卡是USB插口,可以通过如下方式查看我的无线网卡型号:

通过这些型号我依然不知道需要下载什么驱动。Google了一下,这问题很多,本质是 realtek 8188eu 无线驱动在 linux kernel 3.x 中的安装问题.根据硬件id为 0bda:8179 Google知该芯片组是适合Probable Linux driver 8188eu,于是问题就简单了。


2) 到https://github.com/lwfinger/rtl8188eu下载rtl8188eu的源码(rtl8188eu-master.zip)。解压,编译:

$ make all

$ sudo make install


提示安装成功。

重启一下,发现右上角扇形的wifi网络出来了,只需选择对应的无线网络账号,输入密码,就可以上网了。


3) 步骤2)可能会提示缺少dkm包,如果提示,就先安装一个。因为目前电脑没网络,到http://packages.ubuntu.com/lucid/all/dkms/download去下载一个dkm安装包(dkms_2.1.1.2-2fakesync1_all.deb),拷贝到该电脑上,并安装:

~/Downloads$ sudo dpkg -i dkms_2.1.1.2-2fakesync1_all.deb

曾按网友提示,做过如下尝试,均失败:

方法一:

在Realtek官网下载 r8168-8.039.00.tar.bz2,它详细信息:http://www.realtek.com.tw/Downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#2

解压,用 root 运行 install.sh 即可。但对我不成功。错误如下:

可能原因:Linux内核版本不一样,该包不支持我的版本。



方法三:

下载这个https://github.com/Red54/linux-shumeipai2/tree/sunxi-3.0/drivers/net/wireless/rtl8188eu据说支持3.x内核的版本,编译,报错:

/var/lib/dkms/rtl8188eu/0+git20130406/build/include/osdep_service.h: In function ‘thread_enter’:

/var/lib/dkms/rtl8188eu/0+git20130406/build/include/osdep_service.h:1397:2: error: implicit declaration of function ‘daemonize’ [-Werror=implicit-function-declaration]

开始Google了一会,无解,就没继续探索这个问题

但是,后来无意中看到博文:http://yafeilee.me/blogs/51c1ad4015638855d1000002提及上面这个问题的关键, 说这个版本的8188eu 在 3.5.x 内核以下版本都没有问题, 3.5.x 以上就出问题了。解决方法很简单,说是删掉它就可以了:

  diff --git a/include/osdep_service.h b/include/osdep_service.h
   index ed2dae5..e9acb0d 100755
   --- a/include/osdep_service.h
   +++ b/include/osdep_service.h
   @@ -1403,7 +1403,7 @@ static __inline void thread_enter(char *name);

   -       daemonize("%s", name);
   +       //daemonize("%s", name);
           allow_signal(SIGTERM);
   #endif
   #ifdef PLATFORM_FREEBSD

删除后再编译安装则可。估计我前面成功了的那个版本,就是这里被高手修改以后的版本吧~~

最后:

这里是 3.13 内核的解决方法,其它内核的话估计有不同的错误信息,最好去找找有没有兼容新内核的驱动,如果还是没有,就只能自己动手去改代码了。
