New TP Ling VR2600 not allowing Sky

Hi
I have a new TP Link VR2600
I can no longer view the free Sky channels bundled with my package... Sky1 sky2 arts etc etc..
I get an error message

I have a good internet connection all checked and ok
I can view bbc iplayer etc

These sky channels worked with my tpling vr900 (cheaper router) but not my current one
I suspect its a router setting?
Any ideas most welcome
Thanks
CM
