XFi with comcast <Edited> so far in my experience. Got it because <Edited> of overage usage monthly which I was to told about when I signed up. And now the xFi is down for unknown reasons <Edited> Comcast wants to charge my $70 bucks to have one of their technical come to my house to find out why their equipment I'm renting and paying for it <Edited>. Who's running this company? <Edited> I'm so disappointed with Comcast lately it's not funny, and really am thinking of cutting the cord seriously with them.
