Any hep appreciated.

My mum has NTL analogue TV and 2 x NTL phone lines. She has today had a
cable modem installed.

The engineer has told her to wait a few hours before using it and left
her a CD and some cables.

If I went round I'm sure I could have it licked in 2 minutes flat,
however that is not an option.

My mum is not very computer savvy, I need to be able to explain to her
in simple steps what to do and in what order.

Can anyone assist?
