I did try using a killer expensive network switch HP 1810-8G (which I borrowed to test the cable), and everything connects fine, so the cable seems to be working fine

This would seem to point to your inexpensive rubbish switch. Get a decent switch such as Netgear, HP

Ponder gave you a picture of a crossover cable. I think it would be best for a straight. Use his second picture and make both end the same as that picture (T586B).

These days most equipment is auto switching, so it shouldn't matter. That said, straight cables do the job for 90% of applications so straight is best (pin to pin on both sides).

As for pairs, it's:
1,2
3,6
4,5
7,8

As long as those are pairs, you're fine.

I inherited a client with network errors and a cheapo Planet 8 port switch some years back. Installed a relatively inexpensive D-Link 16 port switch and the problems magically disappeared.

I think he just said his pairs weren't crimped properly. Seems like it's firstly a cable fault. If it gives trouble after fixing that then I'd say look at the switch. One of the things I always disliked about an unmanaged but good switch was that it hid cable faults.

Slightly OT but in my case, 3 storey building, network points, switch on middle floor, the cheapo Planet simply lacked the "oomph" to drive the total cable length.

You must use either the 568A or B standard as it makes a big difference which color goes where.

The advice given above stating there is no difference between brown and blue for example is horribly incorrect as they have different twist rates.

Totally legit concern, though in that case my first reaction would be... do I have cable faults - since that would be my doing. That said, I would never use crap like that at a client. Clients who insisted on the cheapest always went elsewhere... that made me happy.

Each pair has a different twist rate, the point of twist rate difference is to eliminate as much cross talk as possible. It's not important which pair goes where, only that each pair has a different twist rate. That's down to the manufacturer and there's nothing you can do about it ;)

Could it be the mini wifi router is having a bit of trouble sending packets back along the cable?

Looks like the wire ordering was at fault.

I just changed the ends, and now it work like magic! :D .

thanks guys!

Changing plugs was helping me many times. Poor contact was my first thought.

Glad is solved now!

I had a crimping tool that went beyond max when you were heavy handed with it, as a result, you'd get intermittent contact issues. At first I blamed plugs until I noticed that squeezing to the 'end' when crimping, sent the contacts too far down.

These tools are very cheap now, R40-R50. Perhaps there is lot of rubbish. Some more expensive R150-R200 were not always good too. I spent some time to get a right one, even it was just for occasional work. It pays. :)

:confused:

Please elaborate & backup with some facts.

On your picture there is: 568A and 568B
The two different ends of a crossover cable, 1 crossed with 3 and 2 crossed with 6

Or like you said, a picha will work better:

586A & 586B are two different wiring standards, pick one and use it on both ends like you are supposed to. When you wire your premises you pick a standard and stick to, get patch panels etc accordingly.

Just because I posted two different wiring standards does not imply I suggest the OP use one on either end to make up a crossover cable.

No, mine cost in the region of R500+
They're mostly MIC
