Wifi 无法在 Acer-Aspire E 15 上使用（Ubuntu 16.04，内核：4.4.0-21-generic）

我无法在新的 Acer-Aspire E15 上使用 WiFi。它只运行 Ubuntu 16.04，内核：4.4.0-21-generic，没有双启动。

这里是无线信息脚本，发布于 paste.ubuntu.com

我尝试了不同的修复方法，这些修复方法是在谷歌搜索后找到的，例如（这和这)，但都不起作用。有人能帮我识别并解决这个问题吗？

编辑：

modinfo ath10k_pci | grep backport
version:        backported from Linux (next-20151120-0-ga78de01) using backports backports-20151120-0-g906a6b3

答案1

您已安装反向移植，但 16.04 中不需要它们，因此我们需要卸载 

cd backports-20151120
sudo make uninstall

如果已安装固件，则重新启动和 wifi 应该可以工作

很少有人拥有多个版本的 backport，因此您可以使用终端内置的自动完成功能。键入cd backports后按 TAB，它应该会为您完成命令。然后，一旦进入 backports 目录，运行sudo make uninstall以卸载 backports 并重新启动

答案2

以防万一有人遇到类似情况：

更新至 4.8 内核

sudo apt-get update && sudo apt-get install linux-generic-hwe-16.04

然后重新启动。
