wifi 测试过程中udhcpc -i wlan0 不分配IP

dinghui

测试WiFi驱动过程中执行 udhcpc -i wlan0 后没有分配搭配IPudhcpc -i wlan0
udhcpc: started, v1.29.0
udhcpc: sending discover
udhcpc: sending select for 192.168.1.102
udhcpc: lease of 192.168.1.102 obtained, lease time 7200

需要把\busybox-1.1.2\examples\udhcp下的脚本simple.script（是simple.script文件，该目录还有个sample.script文件，注意不要复制错了）改名为default.script，放在开发板上的/usr/share/dhcpc/目录下（目录需要自己创建），才能将获取的IP写到指定的网卡中。

修改后获取IP正常
# udhcpc -i wlan0
udhcpc: started, v1.29.0
Setting IP address 0.0.0.0 on wlan0
udhcpc: sending discover
udhcpc: sending select for 192.168.1.102
udhcpc: lease of 192.168.1.102 obtained, lease time 7200
Setting IP address 192.168.1.102 on wlan0
Deleting routers
route: SIOCDELRT: No such process
Adding router 192.168.1.1
Recreating /etc/resolv.conf
Adding DNS server 192.168.0.1
Adding DNS server 192.168.1.1


然后ping下百度
ping -I 192.168.1.102 www.baidu.com
PING www.baidu.com (180.101.49.12) from 192.168.1.102: 56 data bytes
64 bytes from 180.101.49.12: seq=0 ttl=54 time=6.512 ms
64 bytes from 180.101.49.12: seq=1 ttl=54 time=6.943 ms
64 bytes from 180.101.49.12: seq=2 ttl=54 time=6.873 ms


分配IP，联网都正常
