Ubuntu 22.04 LTS系统Wi-Fi每隔几分钟随机断开问题求助

我自己组装了一台PC，装的是Ubuntu 22.04 LTS，之前一直运行得很顺畅，但最近几天遇到了麻烦——主板自带的Wi-Fi会随机断开连接。我重置了路由器，问题还是存在，于是我换了一个USB Wi-Fi适配器，结果没想到这个适配器也出现了同样的断连问题。我打算先从软件/更新故障的方向排查，暂时不想先认定是硬件问题。

我先运行了网络硬件信息查询命令：

sudo lshw -C network

输出如下：

一开始我运行journalctl -b 0 -u NetworkManager的时候，没发现什么异常信息。

Edit：我刚才才意识到运行journalctl的时候忘了加sudo，更奇怪的是，现在网络居然不再随机断连了，这情况有点莫名其妙。

Edit2：后来我用sudo journalctl -b 0 -u NetworkManager重新查看了日志，发现了一些警告信息，日志片段如下：

希望有大佬能帮我分析下这是什么情况，怎么解决Wi-Fi随机断连的问题。
