I would fire up the old BT router temporarily and see if that connects, just to confirm the line is still working. Then go through the set-up of the BT router and compare it with the set-up of the TP-Link just to make sure that the TP-Link is configured correctly.
In particular things like any username and password needed to log into BT's system and the IP config of the WAN side.
If you have a dynamic WAN IP address and the TP Link isn't being allocated one then that suggests it's either not connecting properly or the BT server is failing to recognise it for some reason.
If you have a static IP address check it's been set up correctly.
