STM32F411CEU6未能如愿意把动态获取IP改为静态获取IP，怎么处理？

硬件配置：
STM32F411CEU6开发板，开启SPI
W5500组件,开启DHCP
工程编译通过，运行控制劝输出显示正常

}
目标：
实现从动态获取IP地址等信息变更为设置静态IP地址等信息

编程实现代码：

    wiz_NetInfo net_info = {
        .ip = {192,168,1,220},  .sn = {255,255,255,0},
        .gw = {192,168,1,1},
        .dhcp = NETINFO_STATIC
    };
    wiz_NetInfo conf;
    //设置   
    ctlnetwork(CN_SET_NETINFO, (void*)&net_info);
    LOG_D("IP : %d.%d.%d.%d\r\n", net_info.ip[0],net_info.ip[1],net_info.ip[2],net_info.ip[3]);
    //读取
    ctlnetwork(CN_GET_NETINFO, (void*)&conf);
    LOG_D("IP : %d.%d.%d.%d\r\n", conf.ip[0],conf.ip[1],conf.ip[2],conf.ip[3]);
实现并未能如愿意把动态获取IP改为静态获取IP，请高人指点
