我有一台 Acer Aspire e5-575g-53vg 笔记本电脑，配备 Centos 7 和最新内核 4.7.3-1.el7.elrepo.x86_64。宏碁说我的无线适配器是 Intel Wireless-AC 7265（有什么方法可以验证这一点，而不必拆开笔记本电脑？），但 lspci 没有显示此设备。我下载了linux驱动程序并将它们放入 /lib/firmware 中，正如网站上所说，但我不知道下一步该怎么做。
我也尝试过以下这些说明， 但

答案1
Serge 引导我完成并解决了这个问题。
首先，我的无线适配器是 Qualcomm Atheros Device 0042 (rev 31)。取三行本指南,
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
sudo 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
随后重新启动解决了问题。
需要注意的是，使用预打包的 3.10 内核执行上述步骤不起作用。我必须更新到 4.7 才能让它工作。
