There are 2 different types of routers; A "Modem Router" which has a modem built in, and is designed for ADSL connection like your for example. Then theres just a "Router" which you can plug an external modem into this. Routers without built in modems are normally used for Cable connections.

Your modem cable connects to a DSL filter then into the socket on your wall.

In answer to your question, it appears you are leased a new IP due to your router loosing sync / dropping the connection. You won't be leased a new IP address unless the connection is DROPPED or you manually renew it. This is why I recommend trying a different router.
