I have installed Ubuntu 16.04 on my new Alienware m17 R3 laptop.

• Ethernet model : Killer E3000 PCI-e Gigabit Ethernet Controller
• Wi-Fi model : Killer Wi-Fi 6 AX1650

Currently there is no network devices available.

The following are my outputs from sudo lshw -C network

 *-network UNCLAIMED description: Ethernet controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:3d:00.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list configuration: latency=0 resources: ioport:3000(size=256) memory:b8300000-b830ffff memory:b8310000-b8313fff memory:b8320000-b838ffff memory:b8390000-b83abfff *-network UNCLAIMED description: Network controller product: Intel Corporation vendor: Intel Corporation physical id: 0 bus info: pci@0000:3e:00.0 version: 1a width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix cap_list configuration: latency=0 resources: memory:b8200000-b8203fff

my current linux kernel is 4.15.0-45-generic

I tried as the answer followed

sudo apt-get install git
git clone
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

but it doesn't work.

sudo apt-get upgrade also doesn't work for me.

I tried checking linux-firmware git.

$ git clone git://
$ cd linux-firmware
$ sudo cp iwlwifi-* /lib/firmware/
$ cd ..
$ git clone
$ cd backport-iwlwifi
$ sudo make clean
$ sudo make defconfig-iwlwifi-public
$ sudo make -j4
$ sudo make install
$ reboot

now wireless is working!!!

I searched realtek r8125 linux and downloaded 2.5G Ethernet LINUX driver r8125 for kernel up to 5.6.

Ethernet also works now!!!!
