USB无线网卡驱动RT73的移植

 

1.RT73无线网卡驱动： 
http://www.ralinktech.com.tw/data/drivers/2009_0206_RT73_Linux_STA_Drv1.1.0.2.tar.bz2 

2.解压 
# tar -xvzf   2009_0206_RT73_Linux_STA_Drv1.1.0.2.tar.bz2 
# cd 2009_2006_RT73_Linux_STA_Drv_1.1.0.2/Module 
# cp Makefile.6  ./Makefile 

3.编辑Makefile

4.交叉编译 
# make all 
生成rt73.ko 

5.在嵌入式linux下 
# mkdir /etc/Wireless 
# mkdir /etc/Wireless/RT73STA 
# cp rt73.bin /etc/Wireless/RT73STA/rt73.bin 
# dos2unix rt73sta.dat 
# cp rt73sta.dat  /etc/Wireless/RT73STA/rt73sta.dat 
# /sbin/insmod rt73.ko 
#/sbin/ifconfig rausb0 inet 192.168.2.9 up

#route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.2.1  dev rausb0

ping  192.168.2.1 -t

 

 

# ifconfig rausb0 up     
# iwconfig             
# iwlist rausb0 scanning     
# iwconfig rausb0 essid "your wireless net"       
# iwconfig rausb0 key "your key"                     
设置一下IP地址和DNS，就可以上网了！ 
可使用udhcpc自动获取ip地址 
# udhcpc -i rausb0 

ping一下网关及外网地址
