网络控制器：Qualcomm Atheros Device （rev 30）WiFi不工作
使用Ubuntu 16.04 LTS
通过使用此命令lspci -nn | grep Atheros lspci -nn | grep Atheros我正在跟随o / p。
03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042] (rev 30)
自从过去两天起我无法连接WiFi。（图标和设置中未显示WiFi网络/选项）

如果您知道某些事情，请告诉我如何解决此问题并访问WiFi。
我正在使用ACER Aspire E 15（E5-573G-5147）。
如果您想了解更多信息，请告诉我们。
您应该只需要Ubuntu已包含在最新Linux固件版本中的固件。 安装时
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.158_all.deb sudo dpkg -i linux-firmware_1.158_all.deb
重启
试试这个：
Internet连接了您的以太网卡。
打开一个终端，
按Ctrl + Alt + T.
运行：
exec sudo -i apt-get update apt-get install build-essential linux-headers-$(uname -r) git echo "options ath10k_core skip_otp=y" | tee /etc/modprobe.d/ath10k_core.conf wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz tar zxvf backports-20151120.tar.gz cd backports-20151120 make defconfig-wifi make make install git clone https://github.com/kvalo/ath10k-firmware.git cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/ cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin reboot
每当升级内核时，都必须运行
exec sudo -i cd backports-20151120 make clean make defconfig-wifi make make install
