该操作系统是 Ubuntu 22.04，安装在型号为“DELL Inspiron 13 5379 2-in-1”的笔记本电脑上。
除网络断开连接问题外，其他一切都正常。硬件没有以太网端口，因此我使用的是 TP-Link UE300 适配器。但是，每隔几分钟连接就会失败一次。请参阅以下文件中在发生故障时收集的部分错误消息/var/log/syslog。
遗憾的是，由于字数限制，我们无法包含完整故障周期的日志文件。如有必要，请为我们指定一个上传文件的位置。
我们非常感谢任何提示和建议，如有任何疑问，请告知我们。

适配器已标记为使用 DHCP 获取其 IP 地址，但由于没有 DHCP 服务器响应，因此失败。您可以使用“设置”设置静态 IP 以停止噪音。
