我在笔记本电脑上安装了 Ubuntu 14.04,但发现摄像头、CD 驱动器和无线网卡无法工作
运行“lspci”显示无线网卡

我看不到启用 wifi 选项,因为它是灰色的。
请建议我需要更改哪些设置,我是第一次使用 Linux。
提前致谢。
我还可以看到它已被禁用:

答案1
说它不工作可能意味着要检查成千上万个原因和事情,但首先,我会检查它是否是配置问题或设备缺失。尝试从终端以 sudo 或 root 用户身份执行以下两个命令 - “lspci”和“ifconfig -a”,均不带引号。如果 lspci 没有列出您的卡(仔细阅读每一行以搜索英特尔或网络或 wifi 字符串),但 ifconfig 命令显示它,那么您可能只在 wifi 的正确配置方面存在问题(或 wifi 驱动程序模块的参数)
