If I want to connect an empty port on a routher to the WAN port on another router I need to use a crossover cable, correct? But If I am using a switch, I can connect to a separate router's WAN port without a crossover? Finally, If I want to connect a WAP to an empty port on a router, or switch, do i need a crossover cablem, or will regular cat5 suffice. Thanks for any input.
