我在安装新版 Ubuntu 16.04 LTS 时遇到了问题。除了无线网卡之外，其他都正常工作。事实上，我的 atheros 卡只能连接和查看 5 Ghz 网络。不幸的是，我在工作时使用的是 2.4 Ghz 连接，我无法将我的电脑连接到 AP。
现在我的电脑上使用的驱动程序应该是 ath10k。（我使用 lsmod 看到它）
这是建议命令的输出：

我认为问题在于系统只识别 wifi 802.ac，而不能识别 802.b/g/n
我该如何解决这个问题？
答案1
要升级固件，您可以执行以下操作：
cd ~
sudo apt-get update
sudo apt-get install git
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA9377/hw1.0/CNSS.TF.1.0
mv /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin.orig
sudo cp firmware-5.bin_CNSS.TF.1.0-00267-QCATFSWPZ-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
然后尝试重新启动。
