Network Geeks- Help!!! Cat 6 PITA

[andrewsmith]

Evening all

Just need a bit of advice as a network cable has done my head in today!
Whats happened is we've run a length of cat6 up to a site office in the building twice and we've not got any signals through it.

The additional cable is served through a TPLink Switch which is working as its also sending the networks into my office on site.
At the top end we've been unable to get a signal through the cable.

Any thoughts?

<pedant mode> Its only Cat-6 if installed by a qualified Cat-6 installer </pedant>

Spend £10 on a tester - it will tell you where you went wrong.

For the record, I am not a qualified Cat-6 installer and usually have to make up any cable twice (at least)

I know
It was installed by a Geordie and two Yorkshiremen. So it would be Cat6 Pikey

If its a cable issue its being tested when the sparkies are back on Monday.
Took 2 days for the cable to come in from the supplier and we've used about 16 ends sorting it.

Is it possible to have a box of shagged cable (100m preboxed)

My ISP have used 3 wifi antenna LNB's, 6 wireless routers and numerous ready made and hand made cables on my system so I think anything is possible.

what have you been using to terminate the connector with e.g. is it a simple pliers style or ratchet style tool? to much pressure can cause the wire the sheer inside the connector when you punch down.

i'm not a qualified cat 6 installer either and we only touched on it when i was doing my cisco and it's been a few years

Pliers style Bib
Enough force to clip them

[Bibio]

throw them away and get a proper ratchet style. the cable is heavier and too much force WILL cause problems. if you are going to use pliers then don't go mad, it only has to pierce the sheathing to make contact. even new ratchet type have to be set properly.

to test a box of new cable take the start end and end then test with a multimeter.

Any box/drum of cable could contain damaged cores. I wire hundreds of meters of cat5 per day, however not for networking...

I know a guy who ran in a 90mm cable but couldn't get any continuity when testing, on closer inspection half way along the cable there was a complete break in the cable for a good inch or so!

Back to cat6, get the tester or even simply just look at the plug ends, they are see-through so just check the cores are the same both end and correctly terminated.

[andrewsmith]

The ends have been done 4 times and are right (even wired to connection type B style)

You must've done it wrong then, there has to be signal going down it go grab a set of crimpers and as SK says get a cable tester and rule out the link as an issue.
