This is exactly why I stopped crimping RJ-45's onto cables years back - somehow there is always "small flaw" that you will end up debugging the rest of the day (of-course with the right test/debug equipment it would be easy - but I don't need a new cable often enough to justify the expense).. I once took a course on implemented structured cabling, intended for electricians who was being trained on such installations - it was quite interesting on the geek-level... For one realizing just how fragile UTP cables are and how easily you can degrade them - just by bending them.. Another take-away point was that a "professional" structured cable installation should come with a frequency/capacity test documented for each and every termination, to verify that this particular termination could actually carry the bandwidth that the cable was originally certified for (i.e. to make sure the electrician had not bended the cable too many times). Since then I have discretely asked office/building-managers to see if they had received the documentation from the installation company.... am yet to see one. Finally it was also nice to learn that there are good and well thought-through standards for how to enumerate the various termination points in a building, IBM has a good one as I recall. Downside it makes my toes cringe whenever I see an office where the ports seems to be numbered by random. Maybe I geek too much... .. Mike On 3/29/16 3:36 PM, joe mwirigi wrote:
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.
