購買了一台戴爾桌上型電腦 Alienware i7 六核心 R7 Windows 10 計算機，配有 Killer 1535 有線/無線藍牙卡。
帶回家並安裝了16.04。
安裝時，Ubuntu 無法辨識我的有線連接或無線路由訊號。
DVD/CD 安裝後，仍無法辨識網路。
到目前為止，在線幫助也不起作用。連殺手自己的連結都沒有。
由於。

答案1
在您的 dmesg 中我們看到：
ath10k_pci 0000:05:00.0：無法啟用動態頻寬：-11
這顯然是一個韌體錯誤： https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1520343
請注意，錯誤報告特別提到了您的確切設備：168c:003e。
讓我們升級韌體看看是否有幫助。由於您的裝置上沒有任何互聯網，請在其他電腦上下載此文件，將其傳輸到 USB 隨身碟上，然後將其拖放到目標電腦的桌面上：http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.1_all.deb
現在，在終端機中：
cd Desktop
sudo dpkg -i linux*.deb
重新啟動並告訴我們無線是否正常運作。
答案2
全新下載並安裝解決了問題。
我的電腦是最新版本的 Dell i7 Aurora R7，搭配 Killer 1535 乙太網路卡（有線/無線/藍牙）。一年前的版本不起作用。然而，重新下載並安裝就成功了！
感謝您的所有努力！
答案3
我也在 16.04 上對 AW17R3 進行了同樣的護理：
$ 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
在過去的幾天裡，新的驅動程式被推送到 16.04 和 17.10，所以希望很快，如果您獲得全新安裝的 Live USB，它會正常工作。來自錯誤報告:
你好，我確實確認 linux-firmware 1.157.16 確實解決了這個問題，並且它沒有引入任何對先前版本的回歸。我的筆記型電腦是 Dell XPS，其中包含 Qualcomm Atheros QCA6174 無線網路適配器。
我使用的是內核 4.13.0-32，透過使用韌體版本 WLAN.RM.4.4.1-00051-QCARMSWP-1 api 6，我可以檢查連接是否持續，並且現在可以順利執行幾個小時（當它是前10/15 分鐘後悄悄下降）。
然而這個修復是在建議的部分：https://www.ubuntuupdates.org/package/core/xenial/main/proposed/linux-firmware
我不確定它進入每日構建需要多長時間。
FTR 我有一張單獨的 Killer 有線卡，我每天都會使用它，所以我從來沒有依賴上面的 WiFi 卡。我的有線卡：
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
我認為您應該使用 Cat 5e 電纜（帶有 RJ-45 端的藍色乙太網路）並將其插入筆記型電腦和路由器之間。希望您有一個單獨的乙太網路卡，而且它不是像您所相信的那樣是有線/無線/藍牙組合卡。
答案4
您也許可以使用以下命令啟用乙太網路設備
sudo modprobe alx
echo '1969 e0b1' | sudo tee /sys/bus/pci/drivers/alx/new_id
然後看看乙太網路是否工作
