英特尔公司 Wireless-AC 9560 蓝牙无法在 Ubuntu 上运行。我可以创建驱动程序吗？

我有一台本地制造商（Avell）生产的 PC，它没有用于蓝牙/无线硬件的 Ubuntu 驱动程序。我尝试了您能想到的所有方法，并在以下帖子中详细描述了所有尝试（我仍然认为可以修复）：Ubuntu 18.04.3 蓝牙连接失败：org.bluez.Error.Failed（英特尔® 双频无线-AC 9560 + 蓝牙）

但在与一些专家交谈后，他们告诉我，我需要找到/编写该硬件的驱动程序才能使其完全正常运行。我做了一些研究，但没有找到任何驱动程序。

硬件是Intel Corporation Wireless-AC 9560，当我运行以下命令时您可以看到lspci -knn | grep Net -A2; lsusb：：

00:14.3 Network controller [0280]: Intel Corporation Wireless-AC 9560 [Jefferson Peak] [8086:a370] (rev 10)
    Subsystem: Intel Corporation Device [8086:0034]

我有丰富的编程经验，我愿意自学如何编写驱动程序，但我是一个软 Ubuntu 用户，从未编写过驱动程序或类似程序。任何帮助都非常感谢。

答案1

问题是其中一个天线Intel Corporation Wireless-AC 9560断开了。我打开电脑并连接了天线。现在我的蓝牙可以完美工作了，而且 Wifi 信号更好。
