刚刚在干净的机器上安装了 CentOS 8（带 GUI）。
访问“设置”>“Wi-Fi”时，我收到问号：
未找到 Wi-Fi 适配器 确保已插入并打开 Wi-Fi 适配器
不过蓝牙没啥问题。
在这台机器上，我无法访问以太网连接，但可以插入 USB。
我对该用户有 sudo 访问权限。

我有在这里访问将以下软件包下载到 U 盘：
• NetworkManager-1.22.8-5.el8_2.x86_64.rpm
• NetworkManager-tui-1.22.8-5.el8_2.x86_64.rpm
• NetworkManager-libnm-1.22.8-5.el8_2.i686.rpm
• NetworkManager-libnm-1.22.8-5.el8_2.x86_64.rpm
• NetworkManager-wifi-1.22.8-5.el8_2.x86_64.rpm
将目录更改为 USB 记忆棒，并尝试使用以下命令安装其中一个软件包时
rpm -Uhv $PackageName
我总是遇到失败的依赖错误。
例如。安装时NetworkManager-tui-1.22.8-5.el8_2.x86_64.rpm，我发现我需要以下依赖项：
网络管理器
网络管理器-libnm
如果我尝试安装上述任一版本，也会存在依赖关系，无法完成安装。

从编辑1，读完后这个答案，我尝试过使用
rpm -ihv $PackageName
代替-Uhv。而跑步的时候
rpm -ihv NetworkManager-libnm-1.22.8-5.el8_2.x86_64.rpm
我得到以下信息
warning: NetworkManager-libnm-1.22.8-5.el8_2.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 8483c65d: NOKEY

根据 Artem S. Tashkinov 的建议，我重新启用了缓存，转到与 Internet 连接的计算机（它使用 Windows），下载了软件包kmod-wl-6.30.223.271-32.el8.x86_64.rpm和rpmfusion-nonfree-release-8.noarch.rpm，将它们添加到 USB 记忆棒并将其插入 CentOS 计算机。
在那里我已将目录更改为 USB 记忆棒并运行
rpm -ihv rpmfusion-nonfree-release-8.noarch.rpm
这让我得到了以下结果
warning: rpmfusion-nonfree-release-8.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID bdda8475: NOKEY
error: Failed dependencies:
epel-release >= 8 is needed by rpmfusion-nonfree-release-8-0.1.noarch
rpmfusion-free-release >= 8 is needed by rpmfusion-nonfree-release-8-0.1.noarch
然后跑了
rpm -ihv kmod-wl-6.30.223.271-32.el8.x86_64.rpm
检索到以下内容
warning: kmod-wl-6.30.223.271-32.el8.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID bdda8475: NOKEY
error: Failed dependencies:

答案1
您有一个 BCM43228 wifi 网络适配器。
您必须启用 RPMFusion Nonfree 存储库并安装kmod-wl。不幸的是，这需要有效的互联网连接：
rpm -ivh https://mirrors.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-8.noarch.rpm
dnf install kmod-wl
答案2
只是按照@RuiFRibeiro 的建议并获得了以太网电缆。有了它，该过程变得更快，因为它需要具有各种依赖项的各种包。
除了Artem S. Tashkinov 的建议，这并没有解决我的问题（dnf install kmod-wl这个给了我依赖性错误），我跑了
sudo dnf install kernel
然后
sudo yum install NetworkManager-tui
chkconfig NetworkManager on
service NetworkManager start
然后
sudo yum update
最后
sudo yum install akmod-wl
我关注的一些主题：
。如何在 CentOS 7(CLI)（无 GUI）中连接 wifi？
。无线适配器 (WiFi) 无法工作且未显示在设置中
。BROADCOM 无线驱动程序
答案3
[nik@dlin1 ~]$ lspci -k|grep Network
00:19.0 Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03)
03:00.0 Network controller: Intel Corporation **PRO/Wireless 4965** AG or AGN [Kedron] Network Connection (rev 61)
然后我下载iwl4965-firmware.noarch
并安装了它：
sudo dnf install iwl4965-firmware.noarch
为了看到效果，我必须重新启动。
