RE: Networking problems.

Whilst you have checked that the sockets are correctly pin-to-pin, have you
checked that the pairs are connected properly as pairs (if you see what I
mean)?

Hi Guys,

Just a follow up question to Umar's the other day.

To recap, he's had some network cable fitted to his new house, approx. 70
points on each floor. Currently only the 1st floor is patched in.

Out of the 12 points he has tested so far (by plugging a PC in and trying
to
connect to a device in node 0), 1 works, 1 has tremendous packet loss &
the
rest all fail.

All these points test OK with a basic flashing light network tester, ie all
cables are pin2pin and none appear to be broken.

The origional wireing was faulty, with wires crossed and all sorts, his
sparky has rewired the faulty sockets, at the socket end I beleive.

We have eliminated interference from the electrics as he ran an extension
from downstairs and switched off all the electrics upstairs, same problem.
The electrics from downstairs are totally seperate from the network cable
upstairs.

He took a cable from the back of the patch panel & put a plug on the
end of
it and plugged that straight into the hub, still nothing, so that to my
mind
rules out a faulty patch panel.

Is there a maximum number of cables you should bunch together? All cables
enter node 0 via the same very large hole, and the bunch is the size of a
tree trunk!!

Umar, do you have any photo's of that to demonstrate?

Any other ideas? I'm stumped.
