from the why-you-should-use-good-cables dept. "My printer isn't working." "I can't open my Powerpoint presentation." "Your server is awfully slow!" OK, we check the queues, the computer, the printer itself - but stop. This is not one of our network cables... 
It was not the first time we saw a unshielded Cat3 network cable. They are enough for 10MBit connections but much too weak for 100MBit. You recognise such a cable on the transparent connectors.
Usually you will get a connection to the network with a wrong cable and you will be able to surf, read mail or share files. But the first time you try to transfer a lot af data, you will encounter a really slow transfer rate. Typically you should get about 8-12 MBytes transfer per second - with a wrong cable, it's usually less then a few hundred kilobytes.
A broken or wrong cable takes up to a day to be discovered. The fault will be searched in the servers performance, network throughput or on the client. So be sure to use a good cable. You may get them from your IT supporter or in our office! < | >
