you will need a cable router not an adsl router as they are different technologies

the engineer will just fit the cable modem and then leave you to sort out the networking aspect, all you need do tho is plug the ethernet cable fromthe cable modem into the router (you will need to purchase a new router if isnt cable compatable) wan port, it is best to do this with both router and cable modem turnned off then turn on the router and cable modem

you may need to run the setup disk with the router to start with
