Ron,
I have an ADSL plugged into the first phone socket that comes into the house. One outlet has the wireless router plugged into it, so that permits WiFi laptop connection, the other outlet of the ADSL has a base station of a wireless landline phone plugged into it. The wireless phone can be used anywhere in the house, but it is just one part of a "quad-pack" so there are also three other wireless phones in the house whose bases are just battery chargers and they are positioned where ever they are needed. So, no need for any cables trailing from the first ADSL, and in fact only just the first ADSL needed. All 4 phones connect to the base station to use the land-line connection.
