You are right Rick that if they were bend back and forth like 50 times
or so it could brake the wires inside.
But I would say the problem is with the switch setting or PC they could
be plugged into a 100MB and not a 1Gig Switch or the settings are set
lower all the way down to 10MB and this would make it crawl.
It could also be the settings for there network card or the network card
could just be a slower card not able to run at 1 Gig.

If you ever seen a wiring closet it would scare you most times in most
places.

Do you know if you twist the network wires the data gets corrupted ;)

I agree with Rick *if* the cable is cat5. But if it were good old "fat"
ethernet which is co-ax then yes, sharp bends are known to degrade signal and
introduce interference on this type of cable.

Only if there are an odd number of twists. The real problem is that the ones
slide round the bends faster than the zeros - 'cos ones are thinner and
therefore have less resistance getting through the constriction.

Indeed. Cat 5 can be finicky. I haven't seen that since my old token ring days, and we would have entire network outages that I still don't know the cause of, and I was the S/A. Ah, the joy of spending an afternoon digging holes in the trunk to attach more hubs, then hoping to God that the connection is good.

Have I mentioned how much more fun Remedy is?

** Hey guys
it is pretty obvious I mean, look at it, if there are kinks then the electrons have to travel further you know like going up and down instead of a straight line, so it would slow them down! everyone knows that a straight line is the shortest distance between two points, I think.
this is a classic and should be recorded for posterity!

Hi James,

It is possible for a damaged cable to work, but have degraded performance. This can happen if a networks uses the 100baseT4 spec.

10baseT uses the the following connections on two pairs:
pin 1 - pin 3
pin 2 - pin 6
pin 3 - pin 1
pin 6 - pin 2

100baseTX uses the same pairs as 10baseT, using a higher quality cable.

For both 10baseT and 100baseTX, if the wires were kinked enough to slow data down, they would not work at all.

100baseT4 uses the same two pairs as 10baseT, plus the following two pairs:
pin 4 - pin 7
pin 5 - pin 8
pin 7 - pin 4
pin 8 - pin 5

I've seen a single instance with 100baseT4 where a cable was bent badly enough that one wires to a pin used by 100baseT4, but not by 10baseT failed to carry a signal. In that single instance, pretty much anything hooked to the cable which was 10/100 capable, would auto negotiate 10, since it could not carry a signal at 100.

Chris:

If you have not been told this, the story is false. If the wires were kinked enough to slow data down, they would not work at all.

Hey folks,

Just a bit curious about something I heard.

A company IT department Director told a VP that the reason some folks pc's were slower than others is that when the installation of the network cables was performed, some of the cables were "kinked". And therefore those people would naturally get slower response times..... blah, blah, blah.


I'd like to find out if anybody out there has experienced this phenomenon.

Since we all are in a weird sense that this is Friday....

We actually talked a customer into keeping the token ring card connections because we told him that the ring would be broken if we removed any of the cables and the token would get lost....

(Sort of on the line of Dilbert. he was definately a PHB, with a degree in History.)

My last place I worked we had to deal with Type 1 network wiring and we
still had Token ring now I'm not talking about 5 or 6 years ago this was
last year and it ran at a whole 16MBs what fun.
