I am hoping this will be easier than trying to extract a clear answer from Sky...
We are changing from BT broadband to Sky and we have just received a letter telling us to plug in their router (that comes free with the service) but not until after the service changes over to them, they will then perform a series of checks on speed etc.
As I already have broadband and am happy with my Zyxel router, do I need to do anything or should I just log on to the control panel on change-over day if I need to? Basically I can't be arsed unplugging everything and faffing around if I don't need to.
