Yes
You use the New Modem from your provider which plugs into power and Phone jack.
Using a Ethernet cable plug it into both the new Providers ADSL modem (single lan port) and into your TP link Lan port (any yellow one should do) along with power
This will then work and a hub and Wifi access point for the ADSL.
If the Wifi is not connecting to the internet you may need to route the wifi within the setting of the TP link but it should just be plug and play as before.
