Advice setting up TalkTalk essentials router (d-link DSL-3780) on Plusnet please

[#1]

Hi
Have just moved over to Plusnet and, in a bout of penny pinching have opted to use the above router rather than get one from Plusnet but I seem to be having some problems getting connected. I have managed to login into the router (by typing in the http//number and admin admin etc) A d-link control panel is displayed with some red and green tick/crosses etc. The wifi is green but internet connection in red -  I gues the first thing to ask is the router locked to Taltalk? if not what do I need to do
Your gratefully

It might be but the first thing to try is a hard reset

Some TalkTalk routers aren't locked. Once you've logged in to the router is there a page called 'DSL settings' or similar? If so try entering your plusnet connection details in to that page.

Or your account could be set wrong on our side 
I've fixed that now, can you try connecting again.
