Introduction:
Facing issues with the Ethernet connection on a new motherboard can be incredibly frustrating, particularly when you’re keen to ensure a smooth and efficient system setup.
The anticipation of seamless functionality adds to the annoyance, especially when troubleshooting becomes necessary. However, with the right approach and troubleshooting steps, you can swiftly diagnose and resolve the problem, ensuring a stable and reliable network connection for your PC.
Identifying the Problem:
The first step in troubleshooting a new motherboard’s Ethernet connection is to identify the underlying issue. Start by checking the physical connections, ensuring that the Ethernet cable is securely plugged into both the motherboard’s Ethernet port and the router or modem.
Next, verify that the Ethernet port on the motherboard is enabled in the BIOS or UEFI settings, as it may be disabled by default.
Checking Device Manager:
If the physical connections are intact and the Ethernet port is enabled, but the connection still isn’t working, the next step is to inspect the device status in Device Manager. To access Device Manager, right-click on the Start button and select “Device Manager” from the menu.
Look for the “Network adapters” category and expand it to view the Ethernet adapter. If there’s a yellow exclamation mark or a red “X” next to the Ethernet adapter, it indicates a driver issue or hardware problem.
Updating Drivers:
Outdated or missing network drivers can often cause Ethernet connectivity issues. To update the Ethernet driver, right-click on the Ethernet adapter in Device Manager and select “Update driver” from the context menu.
Choose the option to search automatically for updated driver software, and Windows will attempt to download and install the latest driver version from the internet. Alternatively, you can visit the motherboard manufacturer’s website to download the latest Ethernet driver for your specific motherboard model and install it manually.

Checking Cable and Router:
Sometimes, the problem may not lie with the motherboard or Ethernet adapter but with the Ethernet cable or router. Try using a different Ethernet cable to rule out cable-related issues, and if possible, connect the PC to a different port on the router or switch.
Additionally, power cycling the router or modem by unplugging it for a few minutes and then plugging it back in can sometimes resolve network connectivity issues caused by router glitches or temporary network congestion.
Testing with Live CD/USB:
If you’ve exhausted all software troubleshooting steps and the Ethernet connection still isn’t working, it’s worth testing the connection using a live Linux CD or USB drive.
Booting into a Linux environment bypasses the Windows operating system and drivers, allowing you to determine whether the issue is hardware-related or specific to the Windows installation. If the Ethernet connection works fine in Linux, it suggests that the problem may be related to Windows configuration or drivers.
Checking BIOS/UEFI Settings:
In some cases, the Ethernet port may be disabled or configured incorrectly in the BIOS or UEFI firmware settings. Restart your PC and access the BIOS/UEFI settings by pressing the appropriate key (usually Del, F2, or F10) during startup.
Once in the BIOS/UEFI settings, navigate to the “Integrated peripherals,” “Onboard devices,” or similar section and ensure that the onboard LAN or Ethernet option is enabled. Save the changes and exit the BIOS/UEFI settings, then reboot the system and check if the Ethernet connection is working.
Contacting Manufacturer Support:
If you’ve tried all the troubleshooting steps outlined above and the Ethernet connection is still not working, it’s advisable to contact the motherboard manufacturer’s technical support for further assistance.
Provide them with detailed information about the issue, including any error messages or symptoms you’ve observed, as well as the steps you’ve taken to troubleshoot the problem. They may be able to offer additional guidance or recommend further diagnostics to identify and resolve the underlying issue.
