Ethernet Cable not detected. Local Area Connection not visible.

Ah Sorry HelloItsMeAgain, I thought you were telling him to reinstall Hamachi!

Just misread your post that's all, we're all here to pitch in :)

Here's the before and after images.

Hi DrewO,

After taking a took, you seem to have no Network Drivers installed now (I think you've already said this). To fix this go to: GIGABYTE - Motherboard - Socket 1155 - GA-Z68A-D3H-B3 (rev. 1.0) & download the latest LAN driver and the Ethernet Diagnostic Utility.

Run the Driver installation, restart the PC, let me know what happens!

I managed to install both of them, however an error popped up. Image below.
Regardless, I went ahead and restarted my computer and same results. Nothing new is in the device manager.

I also checked to see if my network adaptor was enabled in the BIOS, and it is. However, it still isn't being displayed in my device manager.

Apparently this is a common problem: Reviving Dead Ethernet Ports [Lnx2Mac's Blog]

I would suggest following the instructions on the site, DONT re-flash your BIOS though as it suggests - Could ruin your board if its not done right!

Let me know what you think.

I may have the answer!

Copied from another forum:

In your BIOS setup program, under Integrated Peripherals there are two settings to be concerned about.

Onboard H/W LAN - Should be set to enabled.
If it is not set to enabled, change the value.

Smart LAN - This is a cable diagnostic of the LAN port. If the LAN setting is set to enabled, open the Smart LAN option.

Without a cable connected the values should read;

Code:

Start detecting at Port.....
Part1-2 Status = Open / Length = 0m
Part3-6 Status = Open / Length = 0m
Part4-5 Status = Open / Length = 0m
Part7-8 Status = Open / Length = 0m

With a cable connected, the value should read out similar to:

Code:

Start detecting at Port..... 
Link Detected --> 100Mbps
Cable Length= 30m

I haven't followed through with everything on the first link, but I'm attempting the Smart LAN test and this is what follows (images below). I'm unsure if I'm to wait for it to start, or I start it myself, but nothing appears to happen on this screen.

Hit Enter, Go For It!

Good Luck :)

I am hitting enter and nothing happens

Does Left Key/Right Key do anything? Up/Down?

Try get it to select 'Virtual Cable Test'.
