标题: 求助CentOS下安装Intel AX200 PCI-e无线网卡问题
请教高人，如何在CentOS 7.5下安装Intel AX200 PCI-e无线网卡。
按照intel提供的linux下无线网卡驱动--英特尔® 无线适配器的 Linux* 支持 (intel.cn)---下载了iwlwifi-cc-46.3cfab8da.0.tgz，解压出一个文件：iwlwifi-cc-a0-46.ucode，并按照readme文档的指导下放在/lib/firmware/目录下。但是我始终不明白linux怎么能让识别出这个网卡。
打开Intel的Readme文档：其中Overview和Installation部分如下，有很多我迷惑的点，搜了好久也没搞清楚，尤其是”kernel's firmware_class infrastructure“，还有一个”firmware loader “是什么东西？

1. OVERVIEW

The file iwlwifi-cc-a0-46.ucode provided in this package must be present on
your system in order for the Intel Wireless WiFi Link AGN driver for Linux
(iwlwifi) to operate on your system.

The "-46" in the filename reflects an interface/architecture version number.
It will change only when changes in new uCode releases make the new uCode
incompatible with earlier drivers.

On adapter initialization, and at varying times during the uptime of
the adapter, the microcode is loaded into the memory on the network
adapter.  The microcode provides the low level MAC features including
radio control and high precision timing events (backoff, transmit,
etc.) while also providing varying levels of packet filtering which can
be used to keep the host from having to handle packets that are not of
interest given the current operating mode of the device.

2. INSTALLATION

The iwlwifi driver will look for the file iwlwifi-cc-a0-46.ucode using the
kernel's firmware_class infrastructure.
More information can be found under Documentation/firmware_class in kernel
source. In order to function correctly, you need to have this support enabled
in your kernel.  When you configure the kernel, you can find this option in
the following location:

      Device Drivers ->
            Generic Driver Options ->
                     Userspace firmware loading support

You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.

In addition to having the firmware_class support in your kernel, you
must also have a working udev and uevent infrastructure configured.
The steps for installing and configuring udev are very
distribution specific.

Once you have the firmware loader in place (or if you aren't sure and
you just want to try things to see if it works), you need to install
the microcode file into the appropriate location.

Where that appropriate location is depends (again) on your system
distribution.  You can typically find this location by looking in the
udev scripts of your distro, the default is /lib/firmware.

Installation of the firmware is simply:

      % cp iwlwifi-cc-a0-46.ucode /lib/firmware

You can now load the driver (see the INSTALL and README.iwlwifi provided with
the iwlwifi package for information on building and using that driver.)

官网不是写明英特尔® Wi-Fi 6 AX200 160MHz驱动要求Linux内核版本大于5.1+了吗，你可以输入uname -a看下内核版本。
安装过程参考centos安装ax200驱动

退货.
买个普通的TP-Link的, 基本开机就可以用.
或者, fenvi,
我在狗东随便买的,
AC1200 WiFi, 还有蓝牙.

比较高端的玩意, 都需要驱动的.
普通的货色, 开机就能工作.

对了系统是 CentOS Linux release 7.9.2009 (Core).

非常感谢回复，可能是我的主机太老了，问题增出不穷:(

非常感谢您的回复，我从其他办公室重新布了一根网线。是我的linux水平太菜，无线连接太让我头秃了@.@

能有线接入，最好是采用网线。稳定可靠。

我最近按老师的较优双路配置了一台
主板不带声卡和wifi
我试了以下几种型号无线网卡或蓝牙适配器都不是即插即用(仅测试centos 8 stream), 仅供参考
腾达（Tenda）U9 650M免驱版 USB无线网卡 5G双频台式机笔记本通用迷你mini 随身WiFi接收器发射器
联想（Lenovo）LX1815 USB蓝牙适配器 5.0,
RicherLink S6000AX WIFI6无线网卡AX210千兆三频5G台式机内置PCI-E+蓝牙5.2接收器
奋威fenvi千兆WiFi6英特尔AX200电竞游戏双频5G台式内置PCIe无线接收器FV-T919 AX200折叠磁吸天线(2400M 蓝牙5.1)
诺可信台式机PCI-E 5.1声道环绕立体声6声道声卡CMI8738芯片独立音频卡PCIE小插槽新

结论: 我在京东买了 SSU 台式机 AX200/AX210无线wifi 6E网卡接收器PCI-E千兆无线网卡蓝牙5.2 AX210
实测centos 8 stream 蓝牙wifi即插即用 ,而且连了蓝牙音箱声音也有了,哈哈(主板不带声卡的)
