Linksys Router Security Checklist

I remember thinking a few years back, what is the basic Linksys Security Checklist for Ethernet DSL and Wireless routers?  

The first place I checked was Linksys Learning Center.  Very cool easy to understand security videos. Then I decided, I wanted to know a bit more information about the Linksys  basic security.  So I checked out a few forums: Afterdawn  for basic wireless and for basic DSL linuxquestions.org 

Enjoy!
