RE: Networking problems.

["Tawn, Jonathan" <jonathan.tawn@xxxxxxxxxxxxxxxxxxxx>]

I've used a 'fluke' network tester in the past - and found them an
invaluable tool to locate network issues...

I've had network cable as thick as a tree trunk coming through metal
suspended ceilings etc, with no problems (of course, there was a rubber
hose
cut in half length ways to prevent any chafing of the cable)

My thoughts, rather than go out and buy new sockets etc. test the
hub/switch
directly. See if that's behaving itself.... Then.. beg/borrow/steal/acquire
etc a fluke network tester and the associated dongle's for it - it will
test
the wiring, display any crossed wires, report any stray protocols etc.

Without the proper test equipment - and especially the amount of cables
need
testing, its like trying to locate a needle in a haystack ! ... unless the
chap that installed it was a monkey and you can see, blatantly where the
fault lies!

Hope this helps.

house, approx. 70
points on each floor. Currently only the 1st floor is
patched in.

PC in and trying
to connect to a device in node 0), 1 works, 1 has tremendous
packet loss &
the rest all fail.

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.

together? All cables
enter node 0 via the same very large hole, and the bunch is
the size of a
tree trunk!!
