Your Belkin N600 would work, but you would only get 100mbps connections (1/10 of capacity of your connection) to the internet, as it only has a 100mbps WAN port.
You should probably get a newer router that has gigabit (1000mbps) ports (both WAN and LAN ports), also at least dual band AC 1200 wireless to take full advantage of your internet connection speed.
Here's a list to start with
