Ubuntu 15.10 上的联想 z50（采用 Qualcomm Atheros）无线功能无法使用

Question

我刚刚在联想 Z50 笔记本电脑上安装了 Ubuntu 15.10，但无线不工作。

$ sudo lshw -C 网络

一开始给了我 *-network UNCLAIMED。感谢本指南我安装了驱动程序，但无线仍然无法工作。也许它已安装，但未运行？上面的命令现在返回：

*-网络

Answer 1

从你的 dmesg 中可以看到，你正在使用来自 kvalo 的 github 的固件，而不是 atondwal 的

fw WLAN.RM.1.1-00141 api 5

Atondwal 的固件会显示

fw atheros-12.0.0.102-fw api 5 

纠正固件问题

cd /lib/firmware/ath10k/QCA6174/hw2.1
sudo wget https://github.com/atondwal/ath10k-firmware/blob/master/ath10k/QCA6164/hw2.1/board.bin
sudo wget https://github.com/atondwal/ath10k-firmware/blob/master/ath10k/QCA6164/hw2.1/firmware-5.bin

重启

您不能简单地将 antondwal 的 github 复制到 /lib/firmware/ath10k，因为 antondwal 的 QCA6164 目录中的固件需要位于 /lib/firmware/ath10k/QCA6174 目录中
