Ok so...

 

This time yesterday I had 3 computers connected via Cat5 network cables and they where all working... I have now relaid my cabling to cat cables, 2 of the computers still work perfectly fine but the newest computer in the house now doesnt detect the network.

 

I have tested the cable with my laptop and it is working fine so I know its not the router or the cable...

 

The computer which isnt working uses an Onboard ethernet card with a Gigabyte GA-990FXA-UD3 Motherboard, there is only 1 ethernet driver on their supports and downloads section for this motherboard which is the one I am using... I cannot find a newer realtek driver to test and am lost for ideas

 

Please Help Me!

 

EDIT:

 

I have just updated my chipset drivers and it still doesnt detect a cable as being plugged in

Just to make sure I understand the problem. You started with CAT5 UTP and upgraded to CAT 6. When connecting the problem computer it does not detect a connection (red X over the network connection). Or does it show connected just not able to find the other PC's or get an IP address?

Make sure your cables are terminated the same at both ends T568A or T568B. You do not want to us a crossover cable between a computer and a switch although routers support MDIX problems it will correct the error with the cable it can cause confusion later on if the cables get changed or moved. Try Reconnecting the computer with the a different cable if possible. Also make sure the locking tab on the RJ-45 jack is not compressed. Gently pry up on the tab and reinsert the plug. If the tab is compressed it wont lock in the connector and it wont properly contact all the pins if the Jack is warn at all. When examining your connectors make sure the Wires are inserted into the connector ALL the way to the end you should be able to see the tip of the wire when looking at the front of the plug. If you have a cable tester check the cable. If the cable test out fine and the computer still wont connect Check the status of the other computers connections and see if the network is running at 10/100/1000 if you right click on the Network connection and click status it will show 1.0 Gbps if its full speed. Next verify the settings on the Newer PC and check under the Advanced Tab- Select Link Speed & Duplex Make sure that it's set to Auto Negotiation. Connect the cable and reboot the computer.

Thanks for the response, I forgot to mention I have simply changed Ethernet card and fixed my issues.

 

You are completely correct with Auto Negotiations though, there is a problem with some onboard gigabyte Ethernet cards and they don't support auto negotiation properly so they are not compatable with CAT6.
