New Motherboard Ethernet Not Working - How To Fix It

If Ethernet isn’t working on a new motherboard, it might be due to faulty drivers, incorrect BIOS settings, defective cables or ports, malfunctioning Windows network settings, or even hardware defects.

Common Causes Of Ethernet Problems On New Motherboards:

Why does my Ethernet not work on my motherboard? Here are common causes of Ethernet problems that users may experience with a new motherboard:

Driver Issues:

Probably the most common cause of problems with Ethernet relates to outdated or missing drivers. Drivers are pieces of software needed by motherboards in order for network interfaces to properly function. Failure of drivers or being outdated can thus lead to issues with the Ethernet port.

Bios Settings:

The Ethernet port can be disabled in the motherboard BIOS settings. Users will want to ensure the onboard LAN or Ethernet option is enabled within the BIOS for networking capabilities.

Faulty Ethernet Port:

Other causes of connectivity issues can be due to physical defects or manufacturing faults in the Ethernet port itself. This may include bent pins, loose connections, or damage internally.

Cable And Port Issues:

Sometimes, the problem is not necessarily with the mother board but rather lies with the Ethernet cable or its port on the router or modem. Faulty wires or faulty ports are causing the problem and often failure when making the connection.

Conflict With Other Hardware:

Hardware conflicts, which occur when two devices attempt to apply their resources or settings to a common resource simultaneously, can also cause problems with Ethernet. This may occur if the computer already has another network card or setting overlaps.

Improper Installation:

If the motherboard is not properly installed in the case or improperly attached for connecting the network cable, it can cause operational issues for the Ethernet port.

Power Supply Issues:

The power supply to the motherboard may be unstable or of low intensity, affecting components such as the Ethernet port. Therefore, a stable power supply is essential for the correct operation of all motherboard components.

Configurations Of The Operating System:

Sometimes, the operating system settings may prevent the Ethernet from working correctly. These settings may include network configurations, firewalls, and other security settings that might prevent the Ethernet port from operating properly.

Defective Motherboard:

In a very few cases, there is a possibility that the motherboard itself has defects and this might hinder the proper functioning of the Ethernet port. This may require warranty claim, especially on a new motherboard.

Solution To Fix Ethernet Not Working On New Motherboard:

Verify Cable And Connection Integrity:

Make sure that your Ethernet cable is not damaged. Check with another cable to eliminate the defect. Also ensure that the cable is well connected to the motherboard and to either the router or modem.

Update Or Reinstall Ethernet Drivers:

Go to the official website for your motherboard manufacturer. Look for the support section of the website, identify your motherboard model, and then download the current network drivers provided. From the website or the files downloaded, follow any further installation instructions to update your drivers.

Enable Ethernet In Bios Settings:

Restart the computer and enter the BIOS screen while pressed a key. Typically it is F2 or DEL or ESC when the system first starts booting. Then navigate to the menu integrated peripherals or onboard devices. Be sure to select onboard Ethernet or LAN to be enabled.

Configure Network Settings In The Operating System:

Open Device Manager. There you can find it by searching on the Windows Start menu and look under “Network adapters”. Confirm that the Ethernet adapter is enabled and has no errors in the box. You can access the Windows Network Troubleshooter by right-clicking the network icon on the system tray and selecting “Troubleshoot problems”. This usually fixes many common connectivity problems.

Test The Hardware:

If possible, attach the Ethernet cable to a different port on your router or switch to rule out a bad port. Check by attaching another device to the same Ethernet cable and port to rule out hardware that might be faulty.

Reset Network Configurations:

On Windows, you would reset all the network settings through the settings menu by selecting ‘Network & Internet > Status > Network reset’. This may resolve some problems generated by wrong settings.

Flash Or Update Bios:

Sometimes, BIOSes can even resolve underlying hardware issues by a BIOS update. Check a motherboard manufacturer’s website for any updates specifically for your motherboard model. Resetting the BIOS to its default, or factory settings, sometimes clears up odd configuration issues that affect hardware functionality.

Consult Technical Support:

If none of the above resolves and your Ethernet still does not work, then you can consider reaching out to the manufacturer’s tech support. There might be a more severe hardware problem that needs professional assistance or replacement.
