I have installed a new motherboard, before I did the internet connection was fine. Now I'm getting errors with connecting to the internet.

I get 'network cable unplugged'.

Here's what i've tried.

1. Drivers updated
2. Two cables (remember they worked before).
4. Turned off the router for 5 minutes.
5. Disabled/Enabled the network adapter several times.
6. Tried ping my router in CMD - PING: transmit failed. General Error
7. I've reset my IP - ipconfig/release * ipconfig/renew - got an error

The only seemingly form progress I can make it when I switch 'Speed and Duplex' to 100 mbps Half Duplex is now reads - 'Undefined Network' and has 10.0 mbps?

Update: I plugged the Ethernet cable into my laptop and it didn't work

Any ideas? it's a brand new motherboard.

To be clear, you state that you plugged the network cable into your laptop and it Did not work, do you mean by this that you had the same problems as on your desktop?

So it doesn't work on your desktop or your laptop or either cable? In that case the problem seems more likely to be with the router.

Correct, did not work.

I've just done some testing with my laptop.

When plugged into the wall port where my PC is it fails. I tried a port in my lounge and my laptop works fine.

I then went into my garage and tried the two ports from my router into my laptop and it worked.

So it's either at the port in the wall in my PC room OR on the slitter in my garage which takes the input from my router and puts it into the cable in the walls.

How can I test and resolve this?

You already found the problem by the looks of it, at least somewhat

At the garage end, that port (I assume it will be numbered at each end) should be patched in to a switch or the router. If it's not, there's your problem. If it is, try removing and re-connecting that patch lead both ends, if it still fails try replacing the patch lead, if it still fails you will need someone to check the actual cabling.

You mean replace my cable or the raw wires that I can see?

Who and how do I arrange someone to come look at this?

OKay - I set my PC up in the lounge and it worked. So my cable between my garage and my PC room is stuffed. It's wired into the wall. What to do?

If you are feeling confident, you could pull the faceplate off the wall at both ends and ensure all 8 little wires are correctly punched down (getting a good connection). The socket in the wall should have colour coding for where the cables are connected (usually will have two sets of colours, marked A and B). If it is the same at both ends, it should be OK.
It almost sounds like an electrician has wired up the LAN cabling without much care or skill (some electricians are no good at it, some are brilliant).

Was your old PC 100Mbps and the new one Gigabit?

You mentioned a "slitter", do you mean a splitter or are you referring to the switch? If you have a splitter at one end of the circuit you need a splitter at the other end also.

Ive noticed lately a lot of the threads where you have had issues lack a lot of helpful details to allow others to be able to help you.

maybe take the time to write up a well thought out detailed post with information on every piece of equipment involved, brand model number how its connected, draw a diagram if needed, or take photos and post them up.

will save countless questions and people left to guess what you are tying to explain or what's wrong.

As helpful as that post.

This started when I thought it as my new motherboard.. testing and questions on other forums lead to where I am now. Thanks for your 2 cents worth though

It's like this (on the right) my router goes into that and that goes out into my house via interior walls

I pulled it out, all wires look like they're in place fine.

Is there a second wire to the same wall point you can try?
