由于无线脚本结果表明您具有Ubuntu 14.04.3 LTS
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty最近已在上游修复此问题，请按照说明安装反向移植的模块和所需的固件
sudo apt-get install build-essential linux-headers-$(uname -r) git
echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/15/backports-20151115.tar.gz
tar zxvf backports-20151115.tar.gz
cd backports-20151115
make defconfig-wifi
make
sudo make install
git clone https://github.com/kvalo/ath10k-firmware.git
sudo 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并且它应该在重新启动后工作
如果您有内核更新并且无线再次退出，则需要
cd backports-20151115
make clean
make defconfig-wifi
make
sudo make install本文收集自互联网，转载请注明来源。
