我在 Ubuntu 20.04.5 LTS 上使用 NUC8i3BEK 的 Wireless-AC 9560。
无线网卡正常工作了几天后，就不工作了。好像是它突然不加载固件（9000-pu-b0-jf-b0-46.ucode）。
我从 获得了转储dmesg | grep iwlwifi。

最后我删除了 OEM 内核，但它仍然不起作用。
[user@iot ~]# uname -r
5.4.0-126-generic
目前，个人电脑作为物联网 (IoT) 运行的设备超过 100 台。
我已经搜索并尝试过解决方案，但都未能解决。
有人能帮忙解决这个问题吗？

谢谢你的帮助。我终于解决了这个问题。但这不是最好的解决办法。方法只是物理上关闭和打开电源。我猜这是硬件问题造成的。
