[我发现了一些东西，但不确定是否相关]
- 有人提到了省电模式。是的，Ubuntu 处于省电模式，但我确实想保持此模式。
- MAC 随机化：尝试启用和禁用，两种情况都会出现断开/重新连接的情况。
- 尝试将我的连接编辑为仅 5GHz 或 2.4GHz。这样可以避免断线，但我仍然想知道问题所在以及更好的解决方案。
- 有人说 NetworkManager 很久以前会定期扫描以获得更好的连接，但现在将这项工作分派给了 wpa_supplicant。这听起来像我的情况，但周期似乎不对。有关更多信息，请参阅下文：https://askubuntu.com/a/1348319/368231
想知道是否有人对此有更多了解，以及是否存在类似的情况，因为环境似乎很正常......提前谢谢。
