Doubling NATing happens when you install two independent routers in series on the same network. If both routers have NAT (Network Address Translation) enabled it may create connectivity, surfing, and application errors. One major concern is the first router assigns a non-routable IP to the WAN port of the second router. Some routers have trouble when assigned a non-routable IP on the WAN port. Additionally, the IP may not even be in the same IP range (i.e. one router uses 192.168.1.XXX and the other uses 10.0.0.xxx).
If you use two routers, you should configure one to be a simple bridge device and disable DHCP and NAT. It doesn't matter which router you choose to bridge (your personal preference), but one of the two must be bridged. Different router manufacturers have unique ways to bridge their equipment so consult the manual for your specific router for more information.
