下载文件时 Wifi 断开连接

我遇到了一个问题——通过 WiFi 下载文件时，中途 WiFi 断开连接，并收到以下消息：

RTL871X: rtw_cmd_thread: DriverStopped(0) SurpriseRemoved(1) break at line 507

以下是日志

从这里下载停止。正在运行的进程

这里什么是 RT 节流？发生了什么事，我该如何解决？如果您需要任何其他信息，请发表评论，我会分享。

答案1

实时节流意味着有实时任务正在消耗大量网络带宽。在某些时候，系统会降低连接速度以保持系统正常运行。在这种情况下，罪魁祸首可能是您用来传输文件的应用程序。可能只需要在偏好设置中进行一些调整。

这可能是您断开 WiFi 连接的原因。

您的第二个问题关于如何连接和断开 wifi，知识库中已经有很多非常好的答案。
