网络控制器显示网络未被认领

我在使用 Ubuntu 14.04 的 Lenovo Flex 3 1480 笔记本电脑连接 wifi 时遇到了困难。它在 Windows 上运行良好。我附上了从以下位置获取的 wireless-info.txt： http://ubuntuforums.org/showthread.php?t=370108

提前致谢

答案1

首先，我建议您删除不正确且可能存在冲突的驱动程序。在终端：

sudo apt-get purge bcmwl-kernel-source

重启然后运行：

sudo modprobe ath10k_pci && dmesg | grep ath

发布结果，并根据结果进一步编辑我的答案以提出解决方案。

您提供的第一个链接是正确的方法；但是，编译过程似乎出了问题。让我们看看是否可以修复它：

cd backports-20151120
make clean
make defconfig-wifi
make
sudo make install
sudo modprobe ath10k_pci

有什么改进吗？如果没有，请重启并再次发布：

dmesg | grep ath

答案2

这个解决了我的问题

sudo aptitude install linux-image-extra-4.4.0-43-generic
  • 您可能想在安装时检查哪个是最新版本。（尝试输入直到“image-extra-”并使用带制表符的自动完成功能来查找最新版本）
  • 我的硬件：联想 x201 上的英特尔 wifi“Centrino Ultimate-N 6300”

答案3

这个问题已通过 Jeremy31 在问题中发表的评论得到解决。

跑步：

sudo dkms remove backath10k/2.0 --all

然后重新启动。

答案4

我已经使用下面的方法上传了已安装的操作系统Settings-> About This Computer -> Details -> Overview -> Install Update

此选项将自动执行必要的更新并解决所有问题
