Network Wiring Question

Home Network:

2 PCs connected to 10/100 Router/Switch in the same room,
1 PC in another room around 100ft to the same switch - 8wire(4pair) Cat5 cable. All NICs are 10/100.
I need to temprorary add 2-nd PC to the second room.

Question:
Should I run 2-nd CAT5 cable or can I use 2 unused pairs from the first cable?
Like I said, it is for few weeks only and really difficult to run new cable over the atic, but could be done.

Thanks.
 
Yes,it can be done. Is it recommended? Hell no. Will it work? I think it will.

If you have an extra foot of slack at each end, a punchdown or crimp tool and a cable tester, and an diagram of which 4 wires carry the signal, you can do this in 15min

Thanks for response, I know which pairs are used, so connection is not a problem.
I am not sure about interferense between 2 signals: all 4 pairs will go close together.
 
I just remembered, last year I saw a network Y jack in the datacomm wharehouse catalog. Basically a fancy version of what we're discussing. You jacked the sucker into a RJ45 walljack and then had 2 new jacks were previously was one (the picture didn't mention/show that another one would be needed at the patchpanel)

Either way, the point is someone already packaged this idea, so it must at least work...sometimes....a little...every now and then ?
 
Yes it will work just fine. However it is unsupported by cabling standards and NOT RECOMMENDED. (ie don't do it at work)

But for you ARK in a home network it will work wonderfully.

Thanks guys,
Will try it tonight.
I am planning to replace single wall jacks with double and reconnect 2 unused pairs ti the second jack.
Also I can slow it down to 10mb,
because it used mostly for internet and occasional file transfers, backups and MP3 dumping to the machine with CD-R.
 
Spidey07: Don't try it at work...

I used to work in a place where did exactly that and more:

To long: 115 meters
Underrated: Cat 3 (cable tester only showed it as cat 2)
Different cobinations:
2 compu's, 1 computer and 2 phones......

Not to mention the mice (The kind with teeth)

Always had a lot to do there. I wonder why?
 
Thanks guys,
Just finished reconnection - networks works fine, will test transfers later.
Now have to go to the store to buy double faceplates - have only single.

Not really standard, but working!
