New router

[19danny94]

Hey so I recently bought a new router for my home, all it came with was a standard Ethernet cable to connect the router to the computer, the thing is the cable I was using for my previous router is too small to fit into the WAN socket but it fits a normal Ethernet cable which i have but it needs to connect into a splitter which has a small socket and does not fit into it my question is are there a cable which has a normal Ethernet cable on one side and a smaller one on the other or and splitter which takes a normal Ethernet cable?

Thanks for reading my post.

Ah, so do I did it the other way around, or do i need both?

Okay i got it working, but in my primary router it wouldn't let me put my older router WAN IP in for DMZ, so instead i put my current computers IP address and it works. Thanks for everything.
