前段时间搞了一下RT73与wpa_supplicant,调通了,无论是什么加密方式和认证类型,RT73都可以良好的工作。可又由于RT73停产了,被迫要使用RT3070。刚开始我以为应该和RT73差不多,果不其然,用法十分接近,但是也有一点点区别的。

1.首先RT73使用的是rausb0表示的,而RT3070使用ra0表示。

2.RT3070的驱动差不多是RT73的两倍多。

3.另外,在使用wpa_supplicant上也有点小区别,主要是wpa_supplicant版本的问题。

下面,我就说一下我的使用过程,希望可以帮助到大家!

首先是驱动的编译,从网上下了好多RT3070的驱动,都没交叉编译过去,只有2009_1106_RT3070_Linux_STA_V2.1.1.0.bz2这一版本的编译过去了,呵呵!

交叉编译过程:

1.tar -jxvf 2009_1106_RT3070_Linux_STA_V2.1.1.0.bz2

2. cd 2009_1106_RT3070_Linux_STA_V2.1.1.0

3.vi makefile

  2.     //DBGPRINT(RT_DEBUG_OFF, ("#/n"));
  3.                 RTMPusecDelay(5000);
  4.             }


 

否则,加载驱动后会一直打印"#",很烦!!!!!

7.cd ../../..

8.make

这时,应该就编译通过了。在2009_1106_RT3070_Linux_STA_V2.1.1.0/os/linux目录下生成了rt3070sta.ko,也就是RT3070的驱动了。

9.把RT2870STA.dat拷贝到/etc/Wireless/RT2870STA目录下

加载驱动过程

insmod rt3070sta.ko

看一下打印消息:

iwconfig看一下

注意wireless_tools之前要移植到开发板上!

接下来就是wpa_supplicant的交叉编译,这个比较麻烦,在这里就不详细说明了,给个网址给大家,我也是参考着做的:

http://blog.csdn.net/farsight2009/archive/2010/06/10/5660878.aspx

不过,我使用的是0.6.10这个版本,其他版本我都没用起来!

由于这个版本比较高,上述网址中的

这些部分就可以略去了,不用做了,呵呵!

顺利地话,就可以在wpa_supplicant-0.6.10/wpa_supplicant下生成wpa_supplicant了!接着就是把wpa_supplicant拷贝到开发板中。

关于wpa_supplicant的使用:

1.把wpa_supplicant.conf拷贝到/etc目录下,当然要根据情况修改wpa_supplicant.conf的内容了!

这里我提供一个我修改的模板,屡试不爽!

  1. ctrl_interface=/var/run/wpa_supplicant
  2. network={
  3.     ssid="XXXXXX"
  4.     scan_ssid=1
  5.     key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE    
  6.     pairwise=TKIP CCMP    
  7.     group=CCMP TKIP WEP104 WEP40    
  8.     psk="XXXXXX"
  9. }


 

其中XXXXXX要替换成相应的ssid和密码!无论是什么加密方式和认证类型,都搞定!WEP除外,因为WEP加密比较简单,在后面会提到,呵呵!!!

2.mkdir -p /var/run/wpa_supplicant

3.最后就是用命令

 wpa_supplicant -B -ira0 -c /etc/wpa_supplicant.conf -Dwext

看一下超级终端的打印:

  17. ==>rt_ioctl_siwfreq::SIOCSIWFREQ[cmd=0x8b04] (Channel=1)


 

 

这过程可能要花费几秒钟!

接着ifconfig一下它的ip,ping一下无线路由器,应该能ping通的。

当然,这些都是让RT3070工作在managed模式下的,工作在ad-hoc模式下的配置跟简单,不需要使用wpa_supplicant!

可以参考里面的iwpriv_usage.txt进行配置,我配置了一下,发现其中有几种情况配置不成功,这里我把配置成功的罗列下来:
