I was working on a last week, basically, correcting what should have been right from the beginning. I often come across incorrect installation. The first two images are what I found; the last one is what I installed.
It may not seem the most riveting of subjects, but a correctly installed network is the backbone of any IT setup, be it in the home or office, and your hashtag is literally the foundation.
Untwisting the wires, as in the first two pictures, can cause problems sending data from your device back to your router ( if you suffer from insomnia, give me a ring and I'll go through it in detail; you'll be out like a light in 5 minutes ).
I've often seen this kind of bad installation over the years, and it's usually carried out by people who generally don't do network installations on a daily basis.
As bad as these are, there are a lot worse examples out there. In my experience, it's often in new build homes. Builders sometimes sell ' home networks ' ( dear reader, they're not really ), some of the quality of the installs is shocking., The data ports don't often work and have clearly never been tested.
It's not just home networks either; I've also come across bad installation in office networks, too.
It's what I like to refer to as a ' Sparky Special'. Not saying that all electricians are bad at running and installing Ethernet networks, but I could count on one hand the good ones I've met.
And yes, I'm rubbish at electrics, I won't touch them or even comment, simply because I don't know enough.
Just to cap it off, the original installer had run some of the indoor cable outside to another part of the house. Technically, you can do this, but it's never recommended. Over time, weather and sunlight begin to break down the quality of the cable and can cause problems ( yes, I did find problems; the cable would only run 100 Mbps max ). That cable was replaced with quality outdoor ethernet, and it's working perfectly.
If you're network is struggling or you're looking for a new office or home network, get in touch.
