Test Packets and CAt5

How you can test the CAT5 cable to make sure it is done right as I had some trouble with many line appear in the tester it is straight through or cross over and the led are on showing it is okay but when we connect it is so slow or failing so what kind of hardware or software can test and measure the accuracy of the sending and receiving the packet,,
Is anyone out there has bad experience of bad cables and is not shown on the tester it is okay but when it is networked are starting to act on and off?

The continuity/pair tester you are using, in general, is not good test for line reliability.  I've had many cables that pass the continuity test but fail in use.  The best way to find out is to use a copper line tester.

Here are some examples: http://www.flukenetworks.com/us/Solutions/Copper+Test+Solutions/Products.htm

These products are on the expensive side but they are a good investment for a Network Admin - especially if you need to guarantee CAT5 spec.  If you only need to test a couple of lines or the testers are just not worth the cost, you might want to try a ping loop test using the cable between two computers...  Just connect two computers up with the line to be tested and run a "PING <computer IP here> -t" from one of the machines to the other.  The -t switch sends out pings indefinitely until you abort (Ctrl+C) the command.  Run that overnight and see the statistics after you abort.  You should get 100% throughput... a score less than 99% might indicate a fault.

Some ethernet cards also have diagnostic driver software that will test lines as well but again you'll need two spare computers to run that test.
