Whenever I try to watch videos on you tube they are always buffering and when eventually do come on they play for about 10 seconds then buffer again. My broadband connection is meant to be 8mb and i'm only down the road from the exchange. The internet seems fine just you tube videos. And sometimes I get the broadband light on the momdem flashing orange and a page appears saying can't connect to broadband just for a minute or two. I use the net on my laptop and samsung galaxy tab. The laptop connected to the momdem and tab wireless and sometimes laptop wireless depending where in the house I am. Any ideas?
