最近我买了一台笔记本电脑 Acer E15 E5-553G-T4TJ，我运行的是 Ubuntu 20.04。

这台笔记本电脑配备了高通 Atheros QCA9377 作为无线网卡，我多次遇到 ping 尖峰甚至断开连接。

在常规使用中，如 YouTube、Google Meet 等，我感觉不到这个问题，但它确实存在。当我尝试玩任何游戏（又名 Lutris 下的英雄联盟）时，我真的有这种感觉。播放时我的 ping 超过 100 毫秒。

首先，我尝试购买一个新的路由器，但它不起作用。所以我决定在终端检查我的延迟，ping Google.com。令我惊讶的是，我发现了高 ping 峰值。对此很感兴趣，我尝试 ping 我的路由器，瞧，我也有我的 ping 尖峰。

这是我到路由器的 ping 日志：

话虽如此，我确信问题不在于我的路由器或 ISP，而在于我的 PC，可能与驱动程序有关。

所以我研究了很多发现什么，我发现高通创锐讯无线卡确实有问题。我找到了很多可能的解决方案，并且我已经尝试了很多。我会尝试链接到我尝试过的任何内容，但我不记得所有内容。

我试过了：

我想这就是我所做的一切，但我不确定。

我注意到当我对 GPU 施加压力时，我的 ping 会出现峰值，所以这可能是相关的。

这是我的日志：

我想就是这样。

请问，有人可以帮我吗？我不知道出了什么问题！:(

先感谢您。
