Hello,
Please I want your help to solve my problem.
We made a home network (8 pcs) without server to using DSL line with rotor (4 ports) and switch (8port),
The largest cable (utb) length was 70 m.
And I made the arrange of the coolers wires on the cable like that (pine to pine)
1-whait/oringe 2-oringe
3-white/green 4-blue
5-white/blue 6- green
7-white/brown 8- brown
First I used a different arrange (pine to pine) also
But it was white/color from 1 to 8
But it worked only with 20m, so I changed like the other.
Now the network is established but it is so slowly and the net line is good
But the problem for me my network is appeared pluged/unplged in my pc my cable length is 55m only my pc.
I think the cable is cutted but I checked it was good, may be it passing near electrical cable I do not now
Please help me

Hey
Have you tried to connect your PC to the network with another cable?
Is the cable that connected to your PC crossed wired by any chance?

Wire colors are not really important, it is the wire pairing with the correct signals that is key. Your original configuration with White/Color would not keed the pairing grouped and you would have really poor performance and a lot of transmission errors.

I sounds like you have either a bad cable somewhere, generating a lot of errors or a situation where the port speed is confused. You may want to start by setting the network up with just 1 machine and then slowly adding machines to see what happens. You may also need to force some of the NIC's to 10 Mbps vs. 100 Mbps to see if this helps.

The other issue is your DSL line should be your bottleneck. If you have a lot of users eating up your DSL bandwidth, your performance to the Internet will suffer, however, you performance within your network should not. If any of the users are using constant or high bandwidth applications like VOIP, streaming, P to P, then this may be your issue.

A 8 node home network is a large home network!! I will be happy when I have all 4 of my machines on the network!

Thanks for your reply
but please first i would like to indicate to that all cables whould be make ths same way from 20m to 70m with the orignal connection which could be blue/ white
orige / white and then to 8 pine to pine, yes i know the clors it is not important but i thank the arrange like the second connection they tell me make pair of the cable like ( bule/white-bule on pine 3 and 6 then when i made all cables like that and it worked except my caple(plugged/unplugged)( it is not the largest one only 55m) (we have 70m but work good)but slowly network and very good net.
the problem for me the cable not cutted on the way because i checked it before, it is may be on electrical filed which i psse near it???????? i do not know

If you want this to work properly, I strongly suggest you stick to industry standards, it avoids confusion. As James says, it's the pairing that's most important, though a little known fact is that the twist rate on different pairs is slightly different to reduce crosstalk between pairs in the cable.

Since there's no reason not to wire them correctly, that's what I'd do.
