Acer Aspire E5 573 在任何 Linux 平台上都没有 Wifi

Question

我用 Windows 10 和 Ubuntu 15.10 双启动了我的笔记本电脑 Acer Aspire E5-573，从第一天开始我就无法在任何 Linux 平台上使用 WiFi。我做了我能做的一切仍然没有用。在 Ubuntu 上没有可供我使用的其他驱动程序，但我完全能够在 Windows 10 上使用 WiFi。我笔记本电脑中的 WiFi 芯片是 Qualcomm Atheros QCA9377 无线网络适配器。请为我找到解决方案。

您似乎需要但缺少所需的固件。通过以太网、系留或任何可能的方式连接互联网，打开终端并执行以下操作：

wget https://github.com/kvalo/ath10k-firmware/archive/master.zip
unzip master.zip
sudo cp -r ath10k-firmware-master/QCA9377 /lib/firmware/ath10k/
sudo mv /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin

重新启动，您的无线应该可以正常工作。
