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-fc703fff

Output 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?
