Ubuntu 18.04 intel wireless ac 9260 在附加驱动程序下显示“此设备不工作”，但 wifi 可以正常工作

我刚刚安装了全新的 18.04。现在我的 wifi 不知为何无法识别，但我现在正在使用 wifi。我不确定这是什么意思，这是它的屏幕截图。

在此处输入图片描述

我尝试了一些可能的解决方案这里，但它们对我不起作用。我也在同一台笔记本电脑上安装了 Windows 10，但完全在另一个驱动器上。另外，值得一提的是，我之前在同一台笔记本电脑上安装了 Ubuntu 18.04，之前没有遇到过这个问题。只有在我第三次尝试全新安装后（不要问，我还在学习），我才遇到这个问题。

我不知道这是否重要，但在安装后，在我设置了正确的时区和所有设置后，我的系统时间还是偏离了 5 小时。我不得不进入 BIOS 更改时间并禁用 Ubuntu 的自动日期和时间设置。否则我甚至无法运行 Ubuntu 更新，因为时间与 Ubuntu 服务器不匹配。无论如何...

以下是一些系统规格：

根据解决方案这里保持原样是可以的，但我不太确定，因为正如我之前提到的，我之前 ubuntu 运行良好，只有在全新安装后才遇到这个问题。如果能得到任何帮助，我将不胜感激。我不知所措，谢谢。

谜团找到了，但还没有解决。这似乎是一个漏洞。如果其他人遇到此问题，请查看该链接。

software-properties-gtk erroneously reports that certain Intel wireless adapter cards are not working
Bug #1859308 reported by Naël on 2020-01-12
Bug Description
On Ubuntu 20.04 (development branch), as of today, Additional Drivers (software-properties-gtk 0.98.6) reports that the device "Intel Corporation: Wireless-AC 9260" is not working, and suggests using a manually installed driver (cf. screenshot).

However the device is working correctly:

  * lsmod | grep iwlwifi, lspci -v, lshw, dmesg | grep iwlwifi all show
    that its driver iwlwifi is in use
  * ls /lib/firmware/*9260* show that the appropriate firmware files
    are present

And I am indeed writing this bug report connected to an ac (5 GHz) wifi network, where I can verify a ~130-160 Mbps download speed, so software-properties-gtk shouldn't report the device as not working and suggest manually installing a driver. Not sure why it says so?

EDIT: bug confirmed as affecting the following Intel wireless adapter cards, and assumedly more to come:

  Intel Wi-Fi 6 AX200
  Intel Dual Band Wireless-AC 3165
  Intel Dual Band Wireless-AC 7260
  Intel Dual Band Wireless-AC 8260
  Intel Wireless-AC 9260

Also for reference here are the specs of Intel adapter cards:
