Just make sure you get the engineer to check all the power levels after fitting the additional stb. They *should* do this anyway but it can depend on how much of a hurry they are in.
They can do this with a little test box but if you leave your PC on at the time you can double check it on the modem when it's reconnected.
And if you do all this before signing the paperwork then they can't leave till your happy!
