设置成静态IP,但是android还会先调用DHCP,这时候如果路由器不支持dhcp,android并不会直接把设置好的静态IP给网卡,而是直接报DHCP错误,然后就不连接了

路由器关闭DHCP的情况
D/Ethernet(  441): Interface eth0 link up
D/NetUtils(  441): dhcp_do_request failed : eth0 (new)
E/Ethernet(  441): DHCP request error:Timed out waiting for DHCP to finish
D/ConnectivityService(  441): Sampling interval elapsed, updating statistics ..
D/ConnectivityService(  441): Done.
D/ConnectivityService(  441): Setting timer for 720seconds
D/dalvikvm(  441): GC_CONCURRENT freed 751K, 12% free 6245K/7072K, paused 6ms+9ms, total 84ms
