I will try and make this clear. I am NOT referring to ANY loss of Speed! I don't need a Speed test or sarcastic comments, though perfectly capable of being just as sarcastic if that's what qualifies for help here!
Virgin has a page that is meant to allow them to remotely test your Router etc for FAULTS. Not speed. But it never works. It will simply flag up 'Sorry we guess this isn't the page you were looking for'
