WSL2 Networking Fix: Mirrored Mode Resolves 100% Packet Loss Issue
Developers using WSL2 on Windows have reported a networking bug where the Linux instance loses all internet connectivity despite the Windows host functioning normally. The root cause is a corrupted or misconfigured NAT-based virtual network adapter, which can break after Windows updates, VPN usage, or sleep cycles. The fix involves creating a .wslconfig file in the Windows user profile and setting networkingMode to mirrored, enabling dnsTunneling, and optionally disabling the WSL firewall. After shutting down and restarting WSL, users report full network connectivity is immediately restored. Mirrored networking mode bypasses the virtual NAT adapter entirely by directly sharing the Windows host's network interface with the Linux environment.
