无人认领的网络显示为网络控制器
我在Ubuntu 14.04上的联想Flex 3 1480笔记本电脑上连接到wifi时遇到了困难。 它在Windows上运行良好。 我附加的wireless-info.txt来自： http ：//ubuntuforums.org/showthread.php？t = 370108

提前致谢
此问题已通过Jeremy31在问题中发布的评论得到解决。 使用sudo dkms删除backath10k / 2.0 –all并重新启动。
首先，我建议你删除不正确的，可能有冲突的驱动程序。 在终端：
sudo apt-get purge bcmwl-kernel-source
重新启动然后运行：
sudo modprobe ath10k_pci && dmesg | grep ath
发布结果，并根据结果，我将进一步编辑我的答案以提出解决方案。
你给出的第一个链接是正确的方法; 但是，编译过程似乎出现了问题。 让我们看看我们是否可以修复它：
cd backports-20151120 make clean make defconfig-wifi make sudo make install sudo modprobe ath10k_pci
有什么改进？ 如果没有，请重新启动并重新发布：
dmesg | grep ath
这个解决了我的问题
sudo aptitude install linux-image-extra-4.4.0-43-generic
- 您可能需要在安装时检查哪个是最新版本。 （尝试键入“image-extra-”并使用自动完成function选项卡查找最新的）
- 我的硬件：联想x201上的intel wifi“Centrino Ultimate-N 6300”
我已使用以下设置 – >关于此计算机 – >详细信息 – >概述 – >安装更新上载了已安装的操作系统
