启动 Wi-Fi 热点时出现错误，内容如下：
打开 Wi-Fi 热点？热点处于活动状态时，无法通过无线网络访问互联网。Wi-Fi 热点通常用于通过 Wi-Fi 共享额外的互联网连接。
我是否需要添加交换端口、桥接器或路由才能使其连接到互联网？我可以在手机上看到热点，但无法连接到它。

感谢您的帮助。
答案1
我已经放弃尝试让我的系统内部 wifi 工作，而是给自己买了一个外部 TP-LINK TL-WR902AC LAN 到 wifi 路由器。
没有太多使用静态/固定 IP 设置 Wi-Fi 的经验我了解到广播 wifi IP（路由器的 IP）需要与手机 IP 匹配！
现在我可以通过 wifi 将手机连接到互联网。
