x210 linux平台USB WIFI移植

armeasy

x210 linux平台WIFI测试方法

一：加载WIFI驱动
insmod /lib/modules/wlan.ko

二：给WIFI设置IP，确定IP在自己的网段：
ifconfig wlan0 192.168.0.123 up

三：在/etc目录下，修改wpa_supplicant.conf文件：
默认内容为：
# WPA-PSK/TKIP

ctrl_interface=/var/run/wpa_supplicant

network={
  ssid="armeasy"
  scan_ssid=1
  key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
  pairwise=TKIP CCMP
  group=CCMP TKIP WEP104 WEP40
  psk="phosphor"
}
注意，这里ssid表示WIFI名称，psk表示WIFI密码，请填写自己对应的名称和密码。

四：建立工作目录
mkdir –p /var/run/wpa_supplicant

五：执行如下指令：
wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf &
如加载成功，会有如下打印：
[root@x210ii /]# wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf &

六：ping路由，这时应该能够PING通路由：
[root@x210ii /]# ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: seq=0 ttl=64 time=13.804 ms
64 bytes from 192.168.0.1: seq=1 ttl=64 time=18.033 ms

--- 192.168.0.1 ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 13.804/15.918/18.033 ms
[root@x210ii /]#

七：添加网关
route  add  default   gw  192.168.0.1
成功后可通过route指令查询：
[root@x210ii /]# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 wlan0
[root@x210ii /]# route  add  default   gw  192.168.0.1
[root@x210ii /]# route

[root@x210ii /]#

八：ping外网
[root@x210ii /]# ping 58.63.236.39
PING 58.63.236.39 (58.63.236.39): 56 data bytes

[root@x210ii /]#
表明已经成功连上外网。上面IP为新浪IP地址。

说明：linux USB WIFI的移植，关键就是如何生成wpa_supplicant工具。用户
可直接从x210 linux_qt平台中提取。

有试过AP么
