My new SR203 router does not connect to my Samsung smart TV but all other devices connected

My Samsung Smart TV Model UE55KS9000TXXU doesn't seem to connect to my new Sr203 router. It picked up the network and I input the password (checked 3 times) and it just doesn't connect. All my other devices skyQ, and apple phones and iPads connected without difficulty. Can anyone advise me how I may resolve this?

If the television has an option for it in network settings, I'd suggest using WPS with a button press on the Sky Broadband Hub (it's cunningly concealed low down on the right hand edge).
