第一步：下載RT3070的無線網卡驅動；解壓得到/opt/2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO
第二步：由於是在虛擬機裏面安裝，所以不存在驅動移植的問題，一般源碼包裏面就已經支持了，直接make,在/opt/2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO/os/linux 目錄下會有RT3070.KO文件；再make install；
第三步：把/opt/2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO 下的RT2870STA.dat 複製到 /etc/Wireless/ (這個目錄需要自己創建).
第四步：cd /opt/2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO/os/linux 這個目錄下，insmod RT3070.ko,如果說這個驅動已存在，就remmod RT3070，再繼續insmod.
第五步：使用命令，ifconfig -a ,此時會看到 ra0這個無線網卡了，啓動無線，ifconfig ra0 up.
第六步：需要移植wireless tools進行聯網和配置
1.下載wireless_tools.29.tar.gz
2.解壓：#tar zxvf wireless_tools.29.tar.gz
3.修改makefile
PREFIX = /home/leo/wirelesstoolsout
CC = /usr/src/usr/local/arm/3.4.1/bin/arm-linux-gcc
AR = /usr/src/usr/local/arm/3.4.1/bin/arm-linux-ar
RANLIB = /usr/src/usr/local/arm/3.4.1/bin/arm-linux-ranlib
4. 交叉編譯：
#cd wireless_tools.29
#make
#make install
5. 複製文件到ARM開發板
拷貝libiw.so.29文件到目標系統/lib/
拷貝用到的幾個程序到目標系統的 /bin/ 目錄下就可以了
iwpriv、iwconfig、iwlist, iwevent, iwspy
至此wireless_tools移植完成
6.設置ip地址及子網掩碼：
# ifconfig ra0 172.31.13.229 netmask 255.255.254.0
7.掃描無線熱點
# iwlist ra0 scan
===>rt_ioctl_giwscan. 14(14) BSS returned, data->length = 1526
ra0 Scan completed :
Cell 01 - Address: 00:23:89:08:02:10
Protocol:802.11b/g
ESSID:"IMUST"
Mode:Managed
Channel:1
Quality:42/100 Signal level:-73 dBm Noise level:-115 dBm
Encryption key:off
Bit Rates:18 Mb/s
Cell 02 - Address: 00:23:89:DC:35:B0
Protocol:802.11b/g
ESSID:"IMUST"
Mode:Managed
Channel:1
Quality:42/100 Signal level:-73 dBm Noise level:-115 dBm
Encryption key:off
Bit Rates:18 Mb/s
Cell 03 - Address: 00:23:89:DC:38:90
Protocol:802.11b/g
ESSID:"IMUST"
Mode:Managed
Ghannel:1
Quality:89/100 Signal level:-55 dBm Noise level:-115 dBm
Encryption key:off
Bit Rates:18 Mb/s
第七步：對網卡進行配置,命令行配置
在/etc/sysconfig/network-scripts目錄下添加ifcfg-ra0文件，添加如下內容：
DEVICE=ra0
ONBOOT=yes
ROOTPROTO=dhcp
進行以上幾步後，可以獲得ip了。但後來又出現不能獲取ip，並且重複以上也沒作用使用
#dhclient ra0
備註：
Linux Force DHCP client (dhclient) to renew ip address
Linux renew ip command
$ sudo dhclient -r //release ip 釋放IP
$ sudo dhclient //獲取IP
Now obtain fresh IP:
$ sudo dhclient
There is no need to restart network service. Above command should work with any Linux distro such as RHEL, Fedora, CentOS, Ubuntu and others. On a related note you can also try out the following commands:
# ifdown eth0
# ifup eth0
# /etc/init.d/network restart
OR
# /etc/init.d/networking restart
通過以上步驟就可以連接外網了。
如果還是無法上網就做一下幾步：
1、/etc/sysconfig/network-scripts目錄下添加ifcfg-ra0文件，添加如下內容：
DEVICE=ra0
ONBOOT=yes
ROOTPROTO=dhcp
2、修改/etc/resolv.conf
nameserver 192.168.0.1
3、重新啓動網絡服務
/etc/init.d/network restart
4、ifconfig ra0 192.168.0.123
5、添加網關或者掩碼
route add default gw 192.168.0.1
route add default gw 192.168.0.1 netmask 255.255.255.0
