Yeah, not a good post by the OP. Let's Hijack this. 
Some newer routers don't care, you can use either kind of cable.
The crossover is only needed when you tie two PCs together without a router or hub. And it you ever have to make a crossover cable for a temporary use, just cut into an old price of patch cable and transpose just two pair of wires. Sloppy. but it works for a temporary absolution to a problem. For the cost of the crimp tool and the other stuff you would need to do a neat job, just buy or trade for and old hub at a flea market.
Now here is something yo might not know. For 100mps Ethernet you can use the spare wires to supply low voltage power or use them for a telephone, intercom or some kind of remote control device. Just avoid high frequency or high voltage. Of the four pairs, only two are really needed for actual data. I use one pair for a telephone extension to my barn. (My 'Office' is in the barn.) I am thinking about what I could do with the other pair. Any ideas?
