购买了一台戴尔台式 Alienware i7 六核 R7 Windows 10 电脑，配备 Killer 1535 有线/无线蓝牙卡。
带回家并安装了 16.04。
在安装过程中，Ubuntu 无法识别我的有线连接或无线路由信号。
DVD/CD 安装后，仍然无法识别互联网。
到目前为止，在线帮助都不起作用。甚至连杀手自己的链接都没有。

答案1
在您的 dmesg 中我们看到：
ath10k_pci 0000：05：00.0：无法启用动态带宽：-11
这显然是一个固件错误： https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1520343
请注意，错误报告中特别提到了您的确切设备：168c：003e。
让我们升级固件，看看是否有帮助。由于此设备上没有互联网，请在其他计算机上下载此文件，将其传输到 USB 密钥上，然后将其拖放到目标机器的桌面上：http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.1_all.deb
现在，在终端中：
cd Desktop
sudo dpkg -i linux*.deb
重新启动并告诉我们无线是否正常工作。
答案2
全新下载并安装解决了该问题。
我的电脑是最新版本的 Dell i7 Aurora R7，配有 Killer 1535 以太网卡（有线/无线/蓝牙）。一年前的版本无法使用。不过，重新下载并安装就可以了！！
感谢您的所有努力！
答案3
我也使用 16.04 并且对 AW17R3 给予了同样的关注：
$ lspci -nnk | grep 0280 -A3
3c:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)

Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
在过去的几天里，一个新的驱动程序被推送到 16.04 和 17.10，所以希望很快如果你得到一个全新的安装 Live USB，它就能正常工作。从错误报告：
您好，我确认 linux-firmware 1.157.16 确实修复了这个问题，并且没有对之前的版本造成任何影响。我的笔记本电脑是戴尔 XPS，它包含一个 Qualcomm Atheros QCA6174 无线网络适配器。
我使用的是内核 4.13.0-32，通过使用固件版本 WLAN.RM.4.4.1-00051-QCARMSWP-1 api 6，我可以检查连接是否持续，并且现在可以顺利运行几个小时（之前它在 10/15 分钟后静默掉线）。
然而这个修复建议的部分：https://www.ubuntuupdates.org/package/core/xenial/main/proposed/linux-firmware
我不确定它要多久才能进入每日构建。
FTR 我有一张单独的 Killer 有线卡，我每天都使用它，所以从不依赖上面的 WiFi 卡。我的有线卡：
3b:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)
Subsystem: Device [0707:2400]
Kernel driver in use: alx
Kernel modules: alx
我认为你应该使用 Cat 5e 电缆（蓝色以太网，带 RJ-45 端）并将其插入笔记本电脑和路由器之间。希望你有一个单独的以太网卡，而不是像你想象的那样是有线/无线/蓝牙组合卡。
答案4
您可以使用以下命令启用以太网设备
sudo modprobe alx
echo '1969 e0b1' | sudo tee /sys/bus/pci/drivers/alx/new_id
然后看看以太网是否工作
