Introduction

Losing Internet access in a virtual machine can be frustrating, especially when you're in the middle of an important task. If you're experiencing this issue with your Windows 10 guest running on VirtualBox, you're not alone. There are several reasons why this might be happening, and in this article, we'll explore some of the possible causes and solutions.

VirtualBox Network Settings

One of the first things to check is the network settings in VirtualBox. Make sure that the network adapter is properly configured and that the guest OS is set to use the correct network adapter. You can do this by following these steps:

Open VirtualBox and select the guest OS.
Click on the "Settings" button.
Select the "Network" tab.
Make sure that the "Attached to" dropdown menu is set to "Bridged Adapter" or "NAT Network".
If you're using a bridged adapter, make sure that the "Name" field is set to the correct network interface on the host machine.

Bridged Adapter vs. NAT Network

A bridged adapter allows the guest OS to connect directly to the host machine's network interface, which can improve performance but may also introduce security risks.
A NAT network, on the other hand, uses a virtual network interface to connect the guest OS to the host machine's network, which can improve security but may also introduce performance issues.

Host Machine Network Settings

Another possible cause of lost Internet access in the guest OS is a problem with the host machine's network settings. Make sure that the host machine's network adapter is properly configured and that the guest OS is set to use the correct network adapter. You can do this by following these steps:

Open the host machine's network settings.
Select the network adapter that the guest OS is using.
Make sure that the "IP address" field is set to a valid IP address.
Make sure that the "Subnet mask" field is set to a valid subnet mask.
Make sure that the "Default gateway" field is set to a valid default gateway.

VirtualBox Guest Additions

The VirtualBox Guest Additions are a set of tools that can improve the performance and functionality of the guest OS. However, they can also cause problems if they're not properly installed or configured. Make sure that the Guest Additions are properly installed and configured by following these steps:

Open the guest OS and select the "Control Panel".
Click on the "Programs and Features" icon.
Select the "VirtualBox Guest Additions" program.
Click on the "Uninstall" button.
Follow the prompts to uninstall the Guest Additions.

VirtualBox Network Filter

The VirtualBox network filter is a feature that allows you to filter network traffic between the host and guest machines. However, it can also cause problems if it's not properly configured. Make sure that the network filter is properly configured by following these steps:

Open VirtualBox and select the guest OS.
Click on the "Settings" button.
Select the "Network" tab.
Click on the "Advanced" button.
Make sure that the "Network filter" dropdown menu is set to "None".

VirtualBox NAT Network

The VirtualBox NAT network is a feature that allows you to connect the guest OS to the host machine's network using a virtual network interface. However, it can also cause problems if it's not properly configured. Make sure that the NAT network is properly configured by following these steps:
