What do I do? I have connected a port shared from another router into my WAN port. Internet not accessible.

What is the subnet of both devices?

Make sure you only have DHCP enabled on the router connected to the internet, otherwise devices connected to the other one might have clashing IP addresses or be on a different subnet and also won't know where to find the gateway.
