求助求助 --- 我尝试了所有建议的方法,但都没有任何效果,所以我仍然需要有人帮助解决这个问题!我怀疑这不是唯一发生这种情况的例子,但在搜索现有问题时没有找到解决办法!提前致谢!求助。2016 年 12 月的某个时候(例行更新后),我在运行 Ubuntu 16.04 LTS 并安装了 Intel Pro 4965 的 Thinkpad T61 上丢失了 wifi。在此之前,系统运行良好,现在无线网络未在网络屏幕上突出显示(有线以太网运行良好),因此没有可用的无线网络。这不是英特尔适配器的问题,因为如果我从旧 CD(显示和告诉模式)启动系统,wifi 就可以正常工作。我是 Linux 新手,不知道很多终端命令,但在互联网上搜索此问题时,执行了一些帖子中要求的命令。它们如下:

答案1
你为 Ubuntu 16.04 安装了错误的内核。通过有线连接互联网并在终端中运行
sudo apt install linux-generic
然后重新启动。
答案2
我在 16.04 上遇到过一次这种情况。我使用终端上的 nmcli 解决了这个问题。
nmcli con up id <network_name>
如果您之前已验证过此网络,则该命令应该可以完成该工作。
