我被打败了。尝试了数百种可能的解决方案，但没有一种能达到我想要的效果。包括从头开始。
如标题所述，我在 Lenovo Ideapad Creator 5 16ACH6 上设置了双启动
网卡输出为：sudo lshw -C network

额外信息：
Windows 的快速启动已被禁用。
BIOS 快速启动已禁用。
Ubuntu 已经多次从完全关闭状态运行。
问题描述：Ubuntu 上的 WiFi 明显变慢，响应时间更长。每隔约 15 分钟，WiFi 就会断线约 30 秒。在我看来，网卡好像停止工作了。WiFi 设置是 2.4GHz 和 5GHz，两个频段设置了不同的名称，所以我怀疑系统是否试图在网络之间跳转。
我不太热衷于 5GHz 连接。但我希望它稳定。这是我的目标。
我将非常感谢您的帮助，因为我在两天的时间里已经与这个怪物战斗了大约 20 个小时。
如果您需要任何其他信息，请告诉我:)
