在商场进行商业wifi布点的过程中,经常有用户反映说wifi连不上了,或者是连上了是一个叹号,分配不了IP。电脑设置了静态IP是可以接入的,check了logread发现打印里面有这么一句“DHCP packet received on ra0 which has no address”,原来是地址池耗尽了,加大地址池也是很难解决这个问题,那就只有缩短租期了。
openwrt的dhcp相关的配置在/etc/config/dhcp文件中,修改了配置需要重启网络。
配置中的start 100,指的是ip地址从100开始,limit 150表示地址池是150个地址,leasetime 12h是租期12小时。最初的配置是这样的
修改后是这样的
租期改为2小时后就很少出现地址池耗尽的问题了。
