Straight cable will have same wire order (by color) at both ends.

Cross-over will have opposite wire order at each ends.

Check the cable by connecting to physical devices and simply give command PING at Command Prompt to check the cable .

Just connect both ends of the cable to the devices and give PING command.

You will need to check the wires if either of the following displays when you Ping:

1) Ping responce time is slow
2) Any of the 4 attemps the Ping command makes doesn't get any responce (Timed out is displayed)

Hope it helps

For checking cross cable the order is little different.
1st end . 1(or-w) 2(or) 3(gr-w) 4(bl) 5(bl-w) 6(gr) 7(br-w) 8(br)
2nd end. 3 6 1 4 5 2 7 8

if you are making many cables you may find it worth while to invest in a cable tester. You can get them as cheap as $10.

There can often be problems with cables that are not visually observable to this is well worth looking into.
