Troubleshooting Network Adapter Detection Issues in VMware ESXi 6.7

When installing VMware ESXi 6.7, you may encounter the error message "No network adapters were detected" during the installation process. This issue occurs when the ESXi installer fails to identify any available network adapters on the host system, preventing the successful installation of ESXi. In this article, we will explore the potential causes of this problem and discuss troubleshooting steps to resolve it.

1. Incompatible Network Adapters

One possible reason for the "No network adapters were detected" error is the use of incompatible network adapters. VMware ESXi has a limited number of supported network adapters, so if you are using a network adapter that is not on the compatibility list, ESXi may not recognize it during the installation process.

To determine if your network adapter is compatible with VMware ESXi 6.7, you can check the VMware Compatibility Guide, which provides a list of supported network adapters for each version of ESXi. If your network adapter is not listed, you may need to obtain a compatible network adapter to proceed with the installation.

If you are using a physical server, you can also check the server manufacturer's website for a list of compatible network adapters for your specific server model. It is important to ensure that both the server and the network adapter are compatible with VMware ESXi 6.7 to avoid any compatibility issues during installation.

In case your network adapter is compatible, but ESXi is still unable to detect it, you can try the following troubleshooting steps.

1.1. Check Network Adapter Compatibility

Verify the compatibility of your network adapter by cross-referencing its model with the VMware Compatibility Guide. If your adapter is not listed, it may not be supported by ESXi, and you will need to find a compatible adapter.

1.2. Update Firmware and Drivers

Make sure your network adapter has the latest firmware and drivers installed. Check the manufacturer's website for the most recent updates and install them on your system before attempting the ESXi installation again.

1.3. Enable Network Adapter in BIOS

Access your system's BIOS settings and ensure that the network adapter is enabled. It is possible that the adapter is disabled in BIOS, causing ESXi to be unable to detect it during installation.

1.4. Check Hardware Compatibility

Check if your hardware configuration, including the motherboard and related components, is compatible with VMware ESXi 6.7. Incompatibilities between the hardware and ESXi can cause network adapter detection issues. Consult the VMware Compatibility Guide and the manufacturer's documentation for your hardware to ensure compatibility.

2. Virtualized Network Adapters

If you are installing ESXi in a virtualized environment, the "No network adapters were detected" error may occur due to incorrect virtual machine configurations or compatibility issues with the underlying hypervisor. Here are a few potential solutions to address this problem:

2.1. Configure Virtual Machine Hardware

Ensure that the virtual machine hardware is properly configured to include a network adapter. In the vSphere Client or vCenter Server, go to the virtual machine settings and verify that a network adapter is added to the virtual hardware.

2.2. Check Network Adapter Compatibility

Confirm that the virtualized network adapter is compatible with the hypervisor you are using to run the virtual machines. Some network adapters may not be supported in certain virtualization platforms.

2.3. Update Hypervisor and Virtual Machine Tools

Ensure that your hypervisor and virtual machine tools are up to date. Check for any available updates or patches, as they may address compatibility issues or bugs related to network adapter detection.

3. Miscellaneous Troubleshooting

If none of the above solutions resolve the "No network adapters were detected" issue, you can try the following additional troubleshooting steps:

3.1. Reset BIOS Settings

Reset your system's BIOS settings to default. Incorrect BIOS settings can sometimes interfere with network adapter detection. Refer to your system's manual or the manufacturer's website for instructions on resetting the BIOS.

3.2. Verify Physical Connections

Fix any loose or disconnected cables between the network adapter and the network switch. Physical connectivity issues can prevent network adapter detection during the installation process.

3.3. Contact VMware Support

If you have exhausted all troubleshooting options and still cannot resolve the issue, it is recommended to contact VMware support for further assistance. Provide them with detailed information about your system configuration and the steps you have already taken to troubleshoot the problem.

Conclusion

In summary, encountering the "No network adapters were detected" error during the installation of VMware ESXi 6.7 can be frustrating. However, by following the troubleshooting steps outlined in this article, you can resolve this issue and successfully install ESXi. Ensure the compatibility of your network adapter, update firmware and drivers, check hardware compatibility, and review virtual machine configurations in virtualized environments.
