Fedora 25 Broadcom 無線 BCM43228 無 WiFi

我知道 Broadcom 不喜歡 Fedora，我已經處理了幾年和版本。過去，安裝 kmod-wl 或 akmod-wl 通常足以讓一切正常執行（在很久以前將 b43 和 b43 legacy 列入黑名單之後）。

我重新啟動網路管理器無濟於事。重新啟動，沒有任何變化。

如果配置

但是 iwconfig

virbr0-nic  no wireless extensions.

virbr0    no wireless extensions.

lo        no wireless extensions.

enp4s0    no wireless extensions.

modprobe 與我在返回之前使用過的任何 wl (akmod-wl; kmod-wl; broadcom-wl)：

modprobe: FATAL: Module ______ not found in directory /lib/modules/4.9.5-200.fc25.x86_64`

當我使用安裝dnf時，模組最終在錯誤的位置嗎？我們正在深入研究這一點，以及我以前研究過的 Linux 是如何工作的。Broadcom-wl 以 fc24.noarch 而不是 fc25.something 結尾是一個問題嗎？任何事，請。

編輯添加

所以它們已安裝，但未在正確的目錄中找到？威士忌探戈狐步舞，結束。

預計到達時間 (3)

$ rpm -qa | grep -e 核心調試

[Kennedy@Shield_Generator ~]$ rpm -qa | grep -e kernel-debug
kernel-debug-devel-4.9.5-200.fc25.x86_64
kernel-debug-devel-4.9.6-200.fc25.x86_64

rpm -qa | grep -e 核心開發

[Kennedy@Shield_Generator ~]$ rpm -qa | grep -e kernel-devel
[Kennedy@Shield_Generator ~]$ 
[Kennedy@Shield_Generator ~]$ 

我有完全相同的問題，我安裝了 kernel-devel

sudo dnf install kernel-devel-4.9.6-200.fc25.x86_64 

然後我按照 Xenox 在他的回答中提到的相同步驟進行操作，現在 wifi 工作正常

確保安裝了正確的 kernel-devel。如果沒有，首先安裝 kernel-devel 包。請注意，kernel-devel 與 kernel-debug-devel 不同。

我猜您已經安裝了 akmods 並收到錯誤“在目錄 /lib/modules/4.9.5-200.fc25.x86_64 中找不到模組 wl”。跑，

# akmods --force
# depmod -a
# modprobe wl

作為 root 或使用 sudo。

我遇到了和你一樣的問題，上面的方法解決了我的問題。
