Wireless N repeater no longer working with a new router.

Wireless N repeater no longer working with a new router.

I have recently been provided with a new Technicolor DWA by my service provider (fibre as opposed to broadband). I had to reset the 3 repeaters in the house to ensure good coverage through the house.
The Wireless N repeaters all connect to the network but say “no internet”.

I set them up just as before with previous routers so I do not understand why they no longer work.

Any ideas?
