您好，我在旧笔记本电脑 Dell D410 上使用 ArchBang（Dell D410 技术规格）。我的无线网络有问题。我的假设（请阅读下面解释为什么我扣除这一点）是我什至无法使用键盘快捷键（fn + F2）启用wifi适配器。在当前安装 ArchBang 版本之前，该盒子在 Windows XP 上运行，并在双启动中使用 ArchBang 的旧版本（不幸的是我不记得确切的版本）。在 Windows XP 上，wifi 运行正常。在旧版本的 ArchBang 上，存在与实际版本的 ArchBang 相同的问题。当我尝试在旧版 ArchBang 上启用 wifi（使用 fn+F2）时，消息：“键盘快捷键映射问题（或类似内容）”被写入 dmesg（或者/var/log/messages抱歉，我记不太清了）。然后将该盒子重新安装到最新版本的 ArchBang，希望能解决该问题。现在，当我按 fn+F2 时，我没有收到任何不在 dmesg 或/var/log/messages.不过，我尝试发出xev并看看会发生什么：结果是所有快捷方式（亮度、声音控制等）都工作正常（实际上也是如此，并且在xev代码中也返回），除了那些控制的快捷方式无线网络（Fn+F2）。所以我的假设是我的问题不是直接与wifi有关，而是与启用适配器有关。 BIOS 中已启用无线，无线 LED 不闪烁。我可以从命令行发出一些命令来启用 wifi 接口，而不是使用 fn+F2 快捷键吗？以下是我发出的命令的输出：

答案1
下面的命令可以解决这个问题：
pacman -S ipw2200-fw
wifi 现在可以工作，但 LED 仍然存在问题。它不闪烁也不亮灯
