dont be sorry, this is what the site is all about .
we are here to help .
you will need to use the ethernet cable (yellow) for the first time to do all the settings .
but if you have wireless adapters for all the pc's once the initial setup is done you can go fully wireless .
might i suggest you use the laptop to do the initial set-up ,using the ethernet cable as this will make it easy for you to be near the router/phone socket.
with the sky router there is not really a lot of setting up to do as most of the settings are built in
(username password)wpa security is already setup as well.
