Which cable for network???

[SiOl]

I managed to get home network to work in the same room. But when i took
second computer away, it doesn't work, as cable is not connected. It's about
15 meters long and it's that standard round 8-wire cable for network (we
call it UTP, i don't know foreign name). Is it possible that there are too
many disturbances? Would i be better if i get shielded cable? I checked
connections and they are fine. I'll try to change connectors tomorrow, but i
doubt it will help.

Does anyone has any experience with it?

There are various grades of cable -- e.g. Cat3, Cat5, Cat5e, Cat6.
You probably want Cat5 or better. Cat3 can cause problems with high
speed networks.

If you attached your own connectors, you may not have got the pairings
right. It is not enough to just connect pin 1 to pin 1, etc. -- each
pin is a member of a pair whose wires are twisted together internally,
and the other pin from that pair must be connected to the other wire in
the twisted pair. You say you "checked [the] connections and they are
fine," but how did you check them -- a simple continuity test is not
enough?

Shielding is of no use in normal installations, since the signals are
differential.

I have cat 5 cable. And yes, i checked continuity test. Can you perhaps give
me any link to guide for this colour- pair guide?
i wired just randomly...

The Linksys site has a good description of how to wire them as I recall.
I don't have the specific URL handy, but if you go to www.linksys.com
I'm pretty sure you can find it fairly quickly in their "tech support"
area. If not, post back here and somebody will supply the precise URL.

Connecting the wires randomly almost certainly is at least part of your
problem. It might even be the whole problem.

Thank you all, guys! I'm sure this IS my problem. Since when i tried whole
thing, i've had cable of 2m lenght only, while real one is 15m. And both
were made same way - i.e same wrong. But it worked on such short lenght.
I'll just run out of connectors, so i'll buy some tomorrow and try. I'll let
you know, but i'm sure it will work.

Thanks again for such quick response.

One more thing maybe: How come that i must connect my ADSL modem to router
with croose cable in order to work?
I was under impression that i must use all straight cables, but i'm
obviously wrong. Now i have crossed for ADSL and straight for computers.

That's a function of whether the modem "expects" to be connected
directly to a PC network card, or through a hub or switch (and the
corresponding "expectation" of the router). Some devices auto-detect
and can use _either_ type of cable.

It's a little like serial connections; now and then you need a null
modem to make a connection work. Think of a crossover cable as the
rough equivalent of a null modem.

Aha. As long it's OK, i don't mind which one, i just read somewhere about
connecting. I guess they didn't explain wha tyou did... Thanks again! I'll
let you know tomorrow, if it works. (keep fingers crossed!)
