我对 Linux 环境还比较陌生,但不得不说,尽管我还处于学习阶段,但我还是很喜欢它。我已使用网络上的实时 ISO 在我的 Dell Inspiron 7559 上安装了 Ubuntu 64 位 18.04 LTS。
一切进展顺利,但我发现我的英特尔 3165 无线驱动程序未被检测到,并且显示 manual-install = true。我做了一些研究并执行了下面提到的步骤。
- 从英特尔网站以 tar.gz 格式下载最新的英特尔 3165 驱动程序
- 提取它们并按照随附的安装指南,我将 .ucode 文件放在 /lib/firmware 中
- 重启系统
我也尝试了帖子中发布的解决方案,复制了 7265 ucode 文件并将其粘贴为 /lib/firmware 中的 3165 ucode 文件。
即使做了上述操作,我仍然无法使用 wifi。更新管理器中的附加驱动程序部分显示该设备为灰色。首次启动时 Wifi 可以使用,但一段时间后它就会停止工作,除非我重新安装,否则系统永远不会再次检测到它,因此我现在不使用 wifi,而是使用以太网。
有人能帮我解决这个问题并指导我如何安装驱动程序吗?以下是一些命令的输出:
