About this tag
VPN interference can disrupt network-dependent features like Miracast wireless display and custom DNS settings on Windows. In troubleshooting the Microsoft Wireless Display Adapter, VPNs are a known cause of connection failures, choppy video, or audio issues because they alter network routing and block Wi-Fi Direct. Similarly, persistent DNS resets in Windows 11 may stem from VPN software overriding user-configured DNS servers upon reboot. Disabling the VPN temporarily is a common first step to isolate the problem. For lasting fixes, adjusting VPN adapter settings or configuring split tunneling can prevent interference while maintaining privacy. These solutions help restore stable wireless display and consistent DNS behavior.
