Thanks @Tony, note taken. Apparently the undisclosed place has a great design covering Km's all done in fiber and standard. !'m the first chinese they've seen in years :( *_______________________________________________________________We must Keep on, We can't stop here * On Tue, Mar 29, 2016 at 5:13 PM, Tony White <tony.mzungu@gmail.com> wrote:
Worth noting...
The cheap RJ45 plugs are intended for crimping on flexible cables which have multiple (usually 7) strands. If you crimp such a plug on solid conductor cable - like oddments of ordinary cat5 cable, then you have one of several possibilities: (a) the pin hits the wire straight on top, and sits too high, or (b) it slides down to the left or right of the conductor, and is twisted, or (c) it cuts the conductor.
With 8 pins in the plug, random chances are that you will get all three variants!
To my knowledge, only Siemon make 'universal' RJ45 plugs, which may be crimped on either solid or flexible cable.
So the solution is either use multi-stranded flexible cable (best) or use Siemon plugs on solid conductor cable.
Cheers, Tony

Hahaha it happens to the best of us. Good thing is once it happens to you, you will be wiser the next time.

@Tony yes! 5/- . Apparently. You spend 1 week prototyping a device and 2 weeks getting a pin to work!

Thanks @Michael And @Jimmy, turns out it was the crimping pins :) Used different ones. As Jimmy had suggested, the pins were not making good contact with the device socket.
Very grateful!

@Jimmy,
We are preparing several straight cables to test this. Will reply after several tests.
Thanks for your time.

Have you tried with a different cable? sometimes the cable termination pin points might not have full contact on some devices whereas on others they are ok.

Tried switching the ports,
Pinging A still results to *unreachable with 0%loss*. i.e. all sent packets are received but still no reply from the device. Connecting B to C (2 computers on the same ports) seems ok and replies.

Thanks Michael,
Let me do just that, will report back.

For a switch/hub or other network device you generally use a straight (non-crossover cable) - for direct device to device connection you will (in most) cases need a crossover-cable.
1. Some (not all) switches have "auto-sensing" ports that apply crossover or not depending on the cable you use - check the actual specifications of your switch. 2. Common issue is that individual ports in a switch might be "fried", hence maybe the port you have connected A into may be dead - try another port.

To network techies,
I've been experiencing a problem which I cannot figure out the cause. I have a device(A) connecting to a switch (S) then a router. If I connect the device directly from a laptop(B), am able to reach the device.
A to B = works
if I connect A to the switch and B to the switch
A to B through S = Not reachable
If I introduce another computer(C) and assign it a similar IP(that of device A)
C to B through S = works.
Device A has no firewall the subnet is the same for all the devices (255.255.255.0) so is the IPs (192.168.0.*).
At first I thought the subject was the problem but C connects to B thro the same setup. or is the device ginxed for real.
Help
