Help with setting up router

[#1]

I purchased the Asus RT-AV68U router today im trying to set it up which seems to be a lot of trouble.
All the right cables etc are used.
Has anyone used this router before, if so could they help me with the setup please?
If i plug my old router in it works fine
any help with the settings would be great
Many thanks
