(I forgot to clarify that when you update /etc/default/grub you should run "sudo update-grub" to apply the changes)
The test I made still doesn't works always. The computer lost connectivity at 06:22 a.m. (the moment when the cron.daily scripts execute), and went back online at 06:47 a.m.
So, although adding "acpi=off noapic" to the startup helped a lot to minimize the problems, it still doesn't work as expected.
