我的网络连接出现了奇怪的延迟问题。
这是 ping 谷歌服务器的结果，对于任何允许 ping 的远程服务器也是如此。

我还注意到增加的模式突然回落到~35ms并有规律地重复。
我的笔记本电脑是 Acer V 17，配备 Qualcomm Atheros QCA61x4 无线适配器。我尝试将驱动程序更新到 12.0.0.230 版本，没有任何变化。
如果我使用有线 PC，到 8.8.8.8 的平均延迟为 25ms，偏差很小。即使使用同一无线网络用我的 Android 手机 ping，延迟也在 25 到 35 ms 之间。我甚至尝试在距离路由器更远的另一个房间使用另一台笔记本电脑，延迟稳定在 25ms，偶尔会因距离而丢失数据包。
当我使用无线网络从笔记本电脑 ping 本地网关时，它看起来很正常：

我的 Wi-Fi 路由器是 ISP 的 Zyxel vmg1312，但正如我所说，到目前为止，这个问题只出现在我的笔记本电脑上。我在 PC 和笔记本电脑上都使用 Windows 10 build 10586。
编辑： 尝试使用有线连接 - 没有问题。再次通过 Wi-Fi 连接后不久，它工作正常了一段时间，然后又开始振荡。
尝试过这解决方案，再次执行几次 ping 操作后返回：

当我使用任务管理器重置服务时，发生了完全相同的事情WlanSvc。它工作了一段时间，然后又恢复了。
答案1
问题解决了，这是电源管理设置的问题。遇到同样问题的人，请尝试将Control Panel -> Power managment -> schema settings (for the one selected) -> Advanced settings -> Wireless adapter其更改为最高性能。
我得到了本地化的窗口，因此路径可能不完全匹配。
