Wifi driver Intel AC 9560 Ubunto not recognizing

Asked by Pedro J E Casaleiro

The Wifi driver Intel AC9560WiFi does not work on a MSI Modern14 A10M with Ubuntu 18.04.
I was able to install it with the additional driver backport-iwlwifi following the instructions of Vlad Pop in https://elementaryos.stackexchange.com/questions/21683/wireless-driver-installation/21685#21685

The current problem is internet became very slow. I tried to speed it by deactivating 802. 11n with
echo "options iwlwifi 11n_disable=1?" >> /etc/modprobe.d/iwlwifi.conf

It made me lost the wifi and I can't recover it.
I thought to reinstall the last update of the driver backport-iwlwifi-dkms-7906, I made the download but don't know how to replace the older one. It does not appear on the Software apps under additional drivers.

What should I do? How can I upgrade the driver?
Shall I upgrade to Ubuntu 19 or 20, will it recognize the wifi driver?
Thanks
Pedro

To undo your file edit, run:

sudo gedit /etc/modprobe.d/iwlwifi.conf

Delete the line you added, save the new file, close gedit and reboot
