It doesn't work. Are you sure it is internal and an issue that can be solve in computer BIOS? Actually I couldn't find there where to disable any network wake request. The only one available was the "wake on lid open" that I indeed disabled just now, but the situation doesn't change.
And besides, computer was sleeping with windows before alongside with ubuntu 18.04, but since i formated computer and installed 20.04, there is no way i can "put computer to sleep". There were no changes in BIOS, just this flaw.
