仅当笔记本电脑正在充电（插入电源）时，WiFi 才会出现严重数据包丢失？

Question

我有一台安装了 Ubuntu 22.04.2 LTS Wayland 的 MSI 笔记本电脑，我已经使用了很多年。

过去几周，我连接到了一些新的访客 wifi 网络，其中一个我定期重新访问。几天前，我注意到，在将笔记本电脑休眠（暂停）后，然后在主网络位置恢复，现在每当我的笔记本电脑插入电源并充电时，都会出现严重的数据包丢失（ping 数据包丢失率在 30%-75% 之间），并且无法连接到已知的 wifi 网络。现在，这也发生在我的主要受保护 wifi 网络上。

因变量是笔记本电脑是否已插入电源并正在充电。我已经更新了它（使用电池供电时），并多次重新启动、关闭和恢复它，但问题仍未消失。有时，如果我插入电源启动或已连接然后插入笔记本电脑，它会工作一分钟左右，然后开始丢包。如果我拔下笔记本电脑的电源，网络几乎立即恢复“正常”运行。

当笔记本电脑插入电源时，以下是出现此问题的示例 ping 结果：

这次实际上比平时更加​​一致；通常丢失的信息更稀少，并且接收的数据包或分组更少。

该笔记本电脑曾出现电池问题，并且有时会在自动挂起一段时间后恢复，但这个网络问题是全新的。

有人知道我该如何解决这个问题，以及问题可能是什么吗？
