CentOS 8 找不到 Wi-Fi 適配器

剛剛在乾淨的機器上安裝了 CentOS 8（帶有 GUI）。

訪問“設置”>“Wi-Fi”時，出現問號：

未找到 Wi-Fi 適配器 確保已插入並打開 Wi-Fi 適配器

不過藍牙沒什麼問題。

在這台機器上，我無法訪問乙太網連接，但是我可以插入 USB。

我有這個使用者的 sudo 訪問權限。

剛剛遇到這個答案。

我已訪問此處以將以下軟體包下載到 U 盤：

• 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

將目錄更改為 U 盤，並在嘗試使用安裝其中一個軟體包時

rpm -Uhv $PackageName

我總是遇到失敗的依賴錯誤。

例如。安裝時NetworkManager-tui-1.22.8-5.el8_2.x86_64.rpm，我知道我需要以下依賴項：

• 網路管理器
• 網路管理器-libnm

如果我嘗試安裝上述任何一種，也存在依賴關係，無法完成安裝。

從編輯 1 開始，閱讀此答案後，我嘗試使用

rpm -ihv $PackageName

而不是-Uhv. 而且跑步的時候

rpm -ihv NetworkManager-libnm-1.22.8-5.el8_2.x86_64.rpm

我得到以下

warning: NetworkManager-libnm-1.22.8-5.el8_2.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 8483c65d: NOKEY

根據 Artem S. Tashkinov 的建議，我已重新啟用記憶體，轉到與 Internet 連接的電腦（它使用 Windows），下載包kmod-wl-6.30.223.271-32.el8.x86_64.rpm和rpmfusion- nonfree-release-8.noarch.rpm，將它們添加到 U 盤並插入 CentOS 機器。

在那裡，我已將目錄更改為 U 盤並執行

rpm -ihv rpmfusion-nonfree-release-8.noarch.rpm

這讓我得到了以下

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

然後跑了

rpm -ihv kmod-wl-6.30.223.271-32.el8.x86_64.rpm

其中檢索到以下

warning: kmod-wl-6.30.223.271-32.el8.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID bdda8475: NOKEY
error: Failed dependencies:
   kmod-wl-4.18.0-147.el8.x86_64 >= 6.30.223.271-32.el8 is needed by kmod-wl-6.30.223.271-32.el8.x86_64

剛剛遵循@RuiFRibeiro 的建議並獲得了乙太網電纜。有了它，這個過程要快得多，因為它需要具有各種依賴關係的各種包。

除了Artem S. Tashkinov 的建議之外，這並沒有解決我的問題（dnf install kmod-wl這個問題給了我依賴錯誤），我跑了

sudo dnf install kernel

然後

sudo yum install NetworkManager-tui

chkconfig NetworkManager on

service NetworkManager start

然後

sudo yum update

最後

sudo yum install akmod-wl

我關注的一些執行緒：

. 如何在 CentOS 7（CLI）（無 GUI）中連接到 wifi？

. 無線適配器 (WiFi) 不工作且未顯示在設置中

。博通無線驅動

您有一個 BCM43228 wifi 網路適配器。

您必須啟用 RPMFusion Nonfree repo 並安裝kmod-wl. 不幸的是，這需要有效的 Internet 連接：

rpm -ivh https://mirrors.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-8.noarch.rpm
dnf install kmod-wl
