我有一台使用了 2 个月的笔记本电脑，搭载 Kubuntu 22.04 ThinkPad T16 Gen 1（16 英寸 AMD）。
uname -a
Linux tp-ThinkPad-T16-Gen-1 5.15.0-60-generic #66-Ubuntu SMP Fri Jan 20 14:29:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
有时（每天几次或每周 1-2 次）我的 WLAN 不再工作。在这些情况下，我似乎已连接到我的网络，但上传和下载流量为 0。我的网络小部件中通常可见 5 个无线网络（靠近时钟，右下角）。当网络不再工作时，只有连接的网络。
如果我断开连接，就不再可见网络了。
正常重启大约需要 30 秒左右。出现此问题时重启大约需要 3 分钟。我在这里看到数百个条目：
journalctl -rb -1

网络/房屋详情：
- 有两层楼，路由器就在我正下方的房间里（直线距离大约 2 米，中间肯定有钢筋混凝土）。
- 中继器位于走廊（直线距离约 4 米，中间仅隔着一堵墙/一扇房门）
- 路由器：FRITZ!Box 7362 SL
- 中继器：FRITZ！WLAN中继器1750E
- 我使用标准 WiFi，中继器上的访客 WiFi 已关闭
- 我只将2-3台设备（2台笔记本电脑，1台手机）直接从房间通过路由器连接到路由器
- 楼上其余设备连接到中继器（原因：中继器靠近微波炉，当它打开时，WiFi 不再工作）
当我处于较长的会话中并且它突然不再起作用时，我会看到：

目前，我需要重新启动才能重新激活我的网络。这sudo service NetworkManager restart
没有帮助。
希望有人知道如何解决这个问题。或者：如何避免重启？
