Comment 4 for bug 1721880

Hi again,
I've got an interesting piece of news: I've recently discovered that the problem only appears when I'm connected to the optical fiber network in the flat where I live during the week; when I use ubuntu with the wi-fi at my home (much slower, at 7 Mbps) everything is working just fine.
I don't know if there is a problem with the management of the fiber network in Ubuntu or if the issue is caused by a wrong configuration of the router.
