Python自动连接已保存WiFi的实现方案

    profile = pywifi.Profile()
    profile.ssid = ssid
    profile.auth = const.AUTH_ALG_OPEN
    profile.akm.append(const.AKM_TYPE_WPA2PSK)

    # 清理旧配置并连接
    iface.remove_all_network_profiles()

    iface.connect(tmp_profile)
    
    # 等待连接完成

# 创建.bat文件调用python脚本
# 设置触发器为开机启动或定时执行
