Windows Sandbox is a desktop environment app that enables users to try out untrusted software without installing anything within the actual Windows OS. It’s a similar feature to virtual machine software that’s more straightforward to set up and consumes less drive space.

However, some users have needed to fix Windows Sandbox not connecting to the internet. When that issue arises, Windows Sandbox starts ok but doesn’t connect to the internet. Consequently, users can’t browse the web and download software in Windows Sandbox.

Windows Sandbox is a rather redundant feature when users can’t browse the web within it. If you need to resolve a similar Windows Sandbox no internet connection issue, one or more of the potential resolutions below might fix it.

How come Windows Sandbox isn’t connecting with the internet?

Windows Sandbox might not be connecting with the internet because of a more general connection issue on your PC. So, checking your internet connection with some of Windows 11’s troubleshooting tools might help resolve the issue.

Some VPN (Virtual Private Network) protocols can cause Windows Sandbox connection issues to arise. If your host PC is connected to VPN, there’s a pretty good chance that’s the reason Windows Sandbox isn’t connecting with the internet.
