Hi all,

On a recent job (electrical) the customer asked if I could add them a point to hard wire his computer to his internet. I put him an ethernet socket at each end, ran a piece of cat 5 in between and terminated with punch tool as per a bt socket. Customer reported not being able to get connected to the internet, they've got a lead out of the router into one socket and a lead into their computer at the other. I went back with a network cable tester so I could check my connections. Plugged into both ends with a long lead in between and it flashed through in sequence all fine.

So from my point of view all looked fine but still no internet. I gave him a long lead which we trailed upstairs and he could get internet fine. The run between sockets is only 10m max. Wondering if anyone could spot anything obvious or had any ideas on what is wrong.

Many thanks

When you tested your new outlet did you watch the lights on both ends of the lead?

The tester I have can show ok one end, but the other end could be wrong.

They haven't plugged in a second adsl filter in series have they? Ive had that before & it stopped internet access


Also when the computer is connected does it get an ip address

Your " as per a BT Socket" might be the issue. You punch all 8 cables according to the colours on the back of the Rj45 socket using Plan B, if they are duel purpose.
Hope this helps

Thanks plugs I just meant the actual physical process of punching. I followed the colour scheme and did the same at both ends

are you running the cable out of a LAN port of the router I presume. When you tested straight out of the router did you use the same LAN port?

The orange and white/green look to be in the wrong place.
You've terminated the cat 5 cable incorrectly, you've removed too much of the cable jacket and allowed the core to become untwisted and seperated. The cable jacket should stop as close to the module as possible.

I was going to mention the cables being untwisted...
At least you have lost of slack left. Try terminating the sockets again. Twist the pairs back together as well.

I got a 20m lead with a plug on each end so I could watch them both together, they all flashed through in sequence

I left him to do that but when I gave him my long lead to try he plugged it in the same port of the router and it worked
