I'm pretty new to Linux outside of virtual machines, first of all, so I'm sorry if any descriptions of my problem are trivial or if I forgot something. I'm using Ubuntu 20.04 with Windows 10 on dual boot on my Desktop PC. Fast boot on Windows 10 is disabled.

My kernel version is Linux 5.4.0-54-generic.

I intended to update my graphics card drivers (RTX 2070) today as Ubuntu seemed a bit laggy to me. I used sudo ubuntu-drivers autoinstall to install my drivers.

ubuntu-drivers devices showed following drivers for my graphics card:

== /sys/devices/pci0000:00/0000:00:03.1/0000:26:00.0 ==
modalias : pci:v000010DEd00001E84sv00001462sd0000C726bc03sc00i00
vendor   : NVIDIA Corporation
model    : TU104 [GeForce RTX 2070 SUPER]
manual_install: True
driver   : nvidia-driver-440-server - distro non-free
driver   : nvidia-driver-450-server - distro non-free
driver   : nvidia-driver-455 - distro non-free recommended
driver   : nvidia-driver-450 - distro non-free
driver   : xserver-xorg-video-nouveau - distro free builtin

After rebooting, Wi-Fi, using the Intel Wi-Fi 6 AX200 networking card (iwlwifi), stopped working for Ubuntu. On Windows it's working fine though. Wi-Fi worked fine on Ubuntu also before using ubuntu-drivers autoinstall. I can't tell anything about Bluetooth, as I have never used Bluetooth before.

Using lspci -nnk | grep 0280 -A3 or lspci -v, the card is still showing up. pic1 pic2

I noticed that lspci -v is not showing a Kernel driver in use for this device? What can I do with this information?

  • lsmod | grep iwl returns nothing, neither does

  • rfkill list all (neither Wi-Fi nor Bluetooth) or

  • sudo find /sys | grep drivers.*21:00 (regarding the number shown at the lspci command).

sudo modinfo iwlwifi shows modinfo: ERROR: Module iwlwifi not found.. Similarly, modprobe iwlwifi shows that it could not find a module by the name iwlwifi.

There are iwlwifi*.ucode files at /lib/firmware or /usr/lib/firmware.

Ubuntu's Software Center does not show the AX200 card under "Additional drivers" though.

Any clue how I can get my Wi-Fi to work again? I don't have any internet on my Linux machine at the moment, as it is not possible for me to use Ethernet from where I am now.

I'm thankful for any help.

I had the same problem after running sudo ubuntu-drivers autoinstall. This solution worked for me: No Wi-Fi settings or connection after switching to NVIDIA graphics driver

sudo apt install linux-modules-extra-5.4.0-52-generic

  • I am using MSI Mag X570 MoBo with Ryz 9-3900. installing modules-extra fixed this issue. Thank you samsam! – Baskar.M Mar 17 '21 at 13:08
