首先,我是一个 Linux 初学者,所以如果我的问题对你来说很简单,请你原谅我。我哥哥给了我他的旧 T420,所以我决定学习 Linux 并在其上安装 Ubuntu。不幸的是,我无法建立 WiFi 连接(我哥哥向我保证,他使用它时可以正常工作),所以我很肯定这不是硬件问题。在终端中,当我输入
lspci
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
我很确定我缺少所需的驱动程序,但我找不到下载它们的方法,因为我习惯于直接从 Windows 下的制造商网站下载它们。如果我看起来太愚蠢了,我很抱歉,但这对我来说都很新。以下是我在其他威胁中发现的命令:

抱歉发垃圾信息,我只是想确保你得到了你可能需要的一切。另外,作为另一条信息,当我启动 PC 时,就在启动 Ubuntu 之前,屏幕上显示英特尔启动代理。他显示一行新内容,说:DHCP... 并在那里等待 30 秒,之后他说缺少了某些东西(太短了,我看不清)然后继续。我看到的所有地方都说,大多数驱动程序都包含在 Ubuntu 中,如果有人遇到这个问题,那他运行的是旧版本。我使用的是 16.04.2,但我也尝试过 17.04 - 没有变化。甚至英特尔也表示,Ubuntu 支持此设备。
顺便说一句,以太网运行良好。
如果有人愿意帮助我 - 谢谢。我在这里坐了 6 个小时,还是搞不清楚。提前谢谢。

现在我觉得自己比 5 分钟前发帖时还要蠢。笔记本侧面确实有一个小开关,可以禁用所有无线通讯。如果我知道这一点,最后几个小时就不会这么艰难了。感谢 Pilot6 的提示。我为留下这篇帖子感到羞愧,但我会留下,也许这会对其他人有所帮助……结案了。
