# 投屏失败

首先检查网络，确保移动设备与电脑连接到同一个网络（局域网）。确认在同一个网络后仍投屏失败，可尝试关闭电脑防火墙。

### Windows 处理方法

1. 选择“开始” 按钮，然后选择“设置” > “更新和安全” > “Windows 安全中心”及“防火墙和网络保护”。
2. 选择网络配置文件：域网络、专用网络 或 公用网络。
3. 在 “Microsoft Defender防火墙”下，将设置切换为“关闭”。

### macOS 处理方法

1. 点击苹果菜单 > “系统设置”，在边栏中选择“网络” ，然后点击“防火墙”。 （可能需要向下滚动。）
2. 如果按钮显示“停用”，那么防火墙已经被关闭，如果不是，请点击“关闭防火墙”按钮。
