I was previously recieving around 16mb sync speeds but now my sync has dropped. I have tried phoning CS but got given excuses; why do you want more speed, its your computer at fault, you only meant to recieve 3mb.

The only difference I can think of between now and when the sync speeds changed: My internet went dead for around an hour 2 weeks ago

I have also posted on sky's forum

What can I do to get my sync speed sorted?
