未检测到无线网卡？

我打开笔记本电脑，看到无线网卡已经安装好了。[硬件]。但我没看到它在工作。

以下是截图 截屏

Wi-fi 设备为 {none}。这是什么意思？是不是我的网卡坏了？有什么解决办法？

另外，我记得我运行了 BIOS 设置这里。我更换了操作系统，安装了所有驱动程序，并且安装了所有音频/视频驱动程序，我还运行了 BIOS。但我想，在那之后，我的无线网确实工作了相当长一段时间，然后我打开 Ubuntu，它就停止工作了。我不确定这是否完全相关。但只是告知一下。我使用的是戴尔 Inspiron 1545。

答案1

如果 BIOS 未检测到设备，则无论操作系统是什么，这都是一个纯粹的硬件问题。lspci未检测到您的硬件。所以是的，很可能是设备坏了。
