求搭救，会是什么原因引起的呢？

[ 290.047818] rtl8723bs: acquire FW from file:rtlwifi/rtl8723bs_nic.bin

荔枝派_ZERO的使用rtl8723bs以及dropbear（总结哈晕哥的和大佬们的，免得自己忘记了）
http://whycan.com/t_2035.html

https://cn.bing.com/search?q=wpa_supplicant%20site:whycan.com

先用wpa工具配网，都不给ssid和密码，就直接获取ip,梁静茹给你的勇气? : (

可以了，按照下面流程：
insmod r8723bs.ko
ifconfig -a
ifconfig wlan0 up
wpa_supplicant -B -d -i wlan0 -c /etc/wpa_supplicant.conf（按照上面步骤走，手机提示有设备连入）
udhcpc -i wlan0（执行这一步才能接人网络）
udhcpc: sending discover
重新添加dhcp，再编译，还是一样
查看网络状态wpa_cli -iwlan0 status
测试网络ping 123.149.232.30
按CTRL+C停止Ping

补充前期准备：
将linux内核中r8723bs.ko放进文件系统
讲rtl8723bs_nic.bin也放进去
一起打包
烧录后，创建目录 lib/firmware/rtlwifi/，把文件放进去，insmod r8723bs.ko

喔，原来如此。
