我的 wifi 直到最近都运行良好。我已将 kvalo/ath10k-firmware.git 中的文件放入 /lib/firmware 中，如下所示 高通 Atheros 中没有 Wifi - Ubuntu 16.04 - Acer Aspire E 15和Ubuntu 16.04 中 Qualcomm Atheros QCA6174 的问题和别的。
但是，我还是遇到了大问题。即使插入 wifi 适配器也会出现问题，但每次都会出现一个问题 - 问题肯定出在这个设备上。我网络上的其他设备都完全正常。
在 Acer Aspire V15 Nitro 笔记本电脑上运行 Ubuntu 16.10。

答案1
我认为你可能遇到了几个不同的问题。我希望你重新安装 Ubuntu 软件包 linux-firmware，因为它可能比 kvallo 的 github 网站更新
sudo apt-get install --reinstall linux-firmware
网络管理器最近更改了默认启用 wifi 省电功能，要禁用此功能，请执行以下操作
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
重启
