I have just changed HOUSES, the new property has a WiFi Router my old computer is using modem for DIALUP connection.
What do I NEED to connect my old computer in order that it works as a dialup connection, while the new house has WiFi router installed?
SetiTelephone line and a dialup ISP, phone CORD between pc and phone wall jack, and adial up ISP package or go into network properties and create a dialup connection to your ISP there.
