happy new year!

I own a Dell Latitude 3490 and since I've changed the OS from Windows 10 to Ubuntu 20.04 i've found some problems with WiFi connection. Connection drops, connections failing, slow internet speed (my link is up to 300Mb/s but on that Latitude only reach ~40Mb/s). I've followed some guides here on Askubuntu and over the internet but nothing changed this scenarios. Can someone bring me a light up, please?
