CAT 5 cable limit

Is there a cable length limitation and what is it?
I connected Belkin 54g wireless router (wireless did not
work really good) to the network card with 100 foot cable
and it does not carry a signal. 10 foot cable works good
if I bring the computer closer.

Thanks, Mike.
 
Hello

Well you will have some issue's but if you can avoid having a cable
that long then avoid it, as to the specific length don't know that
actual number or if their is one

as far as i can remember from my N+ course years ago, cat5 is meant to be
good for 100m point to point. so, theoretically, you're meant to be able to
connect 2 pc's together that are 200m away from each other, with a hub
inbetween.

i could be wrong though... check you 100ft cable with an ohm-meter to see if
it's not faulty.

You're right, q20: 100 meters (328 feet) is the maximum cable length.

However, checking a cable with an ohm-meter (DC continuity test) can't
determine whether the cable will handle the high frequency signals
used in networking, and it can't tell whether the cable is correctly
wired.

Mike, the most likely problem is that the 100 foot cable is
incorrectly wired or otherwise defective. Wires 1-2 must be from one
twisted pair, and wires 3-6 must be from another twisted pair.

Yes, I did check the connectivity. It's not faulty, but
the resistance is 2.5 ohm on each lead. Is it OK?

Mike.
 
sure... that's what i meant... check the cable with an ohm-meter to see if
all the wired hook up correctly... an ohm-meter would be a novel way of
testing the distance you can comfortably reach! *lol*
