我刚刚在 Alienware 15 R2 笔记本电脑上安装了 16.04 LTS，可以通过以太网电缆连接到互联网，但 Wi-Fi 连接丢失。我尝试了发布在这里和这里和这里但都不起作用。以下是我发现人们需要作为详细信息的一些 ant 输出命令。
lspci -nnk | grep -iA2 net; dmesg | grep iwl
输出有两部分：
3b:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)

ls /lib/firmware/ath10k/QCA6174/hw3.0
output is:
board.bin firmware-4.bin notice_ath10k_firmware-4.txt
答案1
您缺少 board-2.bin 文件
cd /lib/firmware/ath10k/QCA6174/hw3.0
sudo wget https://github.com/kvalo/ath10k-firmware/raw/master/QCA6174/hw3.0/board-2.bin重启
