我已经在我的新 Alienware m17 R3 笔记本电脑上安装了 Ubuntu 16.04。
- 以太网型号：Killer E3000 PCI-e 千兆以太网控制器
- Wi-Fi型号：Killer Wi-Fi 6 AX1650
目前没有可用的网络设备。
以下是我的输出sudo lshw -C network

我当前的 Linux 内核是4.15.0-45-generic
我尝试了一下，答案如下 https://askubuntu.com/a/1028199/1098923
sudo apt-get install git
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
但它不起作用。
sudo apt-get upgrade对我来说也不起作用。

我尝试检查 linux-firmware git。
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
$ cd linux-firmware
$ sudo cp iwlwifi-* /lib/firmware/
$ cd ..
$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
$ cd backport-iwlwifi
$ sudo make clean
$ sudo make defconfig-iwlwifi-public
$ sudo make -j4
$ sudo make install
$ reboot
现在无线网络已正常运作！

我搜索realtek r8125 linux并下载了2.5G Ethernet LINUX driver r8125 for kernel up to 5.6。
以太网现在也可以工作了！！！
