通过 WiFi 连接本地路由器时 ping 值较高

我注意到这个主题中也有类似的问题。但这些解决方案并不能解决我的问题......

ping 本地路由器报告：

我尝试关闭电源管理器，但它在我的计算机上不起作用。现在，iwconfig 报告：

我有两台机器（PC 和笔记本电脑）在同一个网络上运行，它们都安装了双操作系统（ubuntu 和 windows）。此问题仅发生在 ubuntu 系统中。所以我认为这是一个与操作系统有关的问题。

我遇到了同样的问题并通过添加以下行解决了它：

options iwlwifi 11n_disable=1

到此文件：

/etc/modprobe.d/iwlwifi.conf
