HP Elitebook x360 1040 G6 Intel AX200 未找到 wifi

Question

我正在尝试让 wifi 在我的 hp elitebook 上运行。我尝试从这里复制固件文件：

https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-io/wireless-networking.html

到 /lib/firmware 但没有成功。

我目前在 ubuntu 18.04.1 上运行内核 5.3.0-28-generic，所以它应该受到支持。

Lspci 显示 iwlwifi 驱动程序已加载，但 wifi 仍然没有显示。

6c:00.0 Network controller: Intel Corporation Device 2723 (rev 1a)
    Subsystem: Intel Corporation Device 0088
    Kernel modules: iwlwifi

Demsg 在尝试加载 wifi 驱动程序时显示错误：

$ dmesg | grep iwl
[   51.551480] iwlwifi 0000:6c:00.0: enabling device (0000 -> 0002)
[   51.919499] iwlwifi: probe of 0000:6c:00.0 failed with error -110

不确定这里还能尝试什么。
