Wifi Intel not working with Ubuntu 18.04.3 LTS - Lenovo Ideapad 730S

[aafgarci]

Hi,

I have a new Lenovo Ideapad 730S and my wifi is not working (it was when I installed Ubuntu a few days ago).

Some information:

Network controller [0280]: Intel Corporation Wireless-AC 9260 [8086:2526] (rev 29)
Subsystem: Intel Corporation Device [8086:0014]
Kernel modules: iwlwifi

Linux 5.3.0-28-generic

Any suggestion? Many thanks in advance
