So, straight-through cable is used to connect between your router and your machine.
But I looked at my book one more time, and it says:
Straight-through is used to connect:
1. Host to switch or hub
2. Router to switch or hub
Crossover is used to connect:
1. Switch to switch
2. Hub to hub
3. Host to host
4. Hub to switch
5. Router direct to host
Now, I don't understand why the book says crossover is used to connect "Router direct to host". Am I not reading it right or something? Doesn't that mean a crossover cable connects between a router and a machine?

Sorry it's on page 32, not 23

newer models of networking equipment use Ethernet ports that have MDI/MDI-X capabilities which detect the need to either cross the TX-RX pairs or not...that is why older networking books refer to the need of a cross-over or "uplink" cable..

MANY - but by no means all - active networking devices - routers, hubs, NIC's etc, are smart enough to work out whether you are using a straight or crossover cable, and to operate accordingly.
It's not a good idea though... just becasue of that one day when you run across a piece of hardware that doesn't.

what that means is that your router does NOT contain a hub or switch, assuming it is the router instruction book you are quoting.
In that case, I would suggest you follow the instructions, and use a crossover cable. (WHEN IN DOUBT, FOLLOW THE INSTRUCTIONS!!)
(I have never seen one that was set up that way, myself. MOST routers, if they have more than 1 connection, have a built-in switch! YOURS apparently does not, NOR does it have "autoswitching" for the connection.)
