Ubuntu 20.04
I've tried several answers from other similar questions.
After changing from Nouveau to NVIDIA driver, I now don't have any WiFI settings (no icon in the taskbar, nothing but VPN settings in network settings, no connection).
Switching back to Nouveau doesn't fix it.
My WiFI card is Intel 6 AX200
Out put of lshw -C Network (the WiFI part):
*-network UNCLAIMED description: Network controller product: Wi-Fi 6 AX200 vendor: Intel Corporation physical id: 0 bus info: pci@0000:03:00.0 version: 1a width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix cap_list configuration: latency=0 resources: memory:fc700000-fc703fffOutput of sudo modprobe iwlwifi:
modprobe: ERROR: ../libkmod/libkmod-module.c:838 kmod_module_insert_module() could not find module by name='iwlwifi'
modprobe: ERROR: could not insert 'iwlwifi': Unknown symbol in module, or unknown parameter (see dmesg)Seems the driver isn't being picked up(?) though I've manually downloaded it myself to try to fix this and moved it to /lib/firmware and rebooted.
Any ideas?

I also faced exact missing iwlwifi issue after installing recommended nvidia drivers using sudo ubuntu-drivers autoinstall. Ubuntu was using my country ppa mirrors which probably were outdated. I fixed this issue by
- rebooting to old kernel version using GRUB menu (2nd option)
- Switching PPA to global mirrors and reinstalling nvidia drivers using same autoinstall command.
- Running
sudo apt update && sudo apt upgrade -yto update again to latest kernel - Reboot. At this point GRUB entry pointing to latest kernel should work without any issue.
You need to install linux-modules-extra-5.4.0-52 by
sudo apt install linux-modules-extra-5.4.0-52-genericIt is weird that it didn't install automatically on a kernel upgrade. Probably you've interrupted an upgrade.
