Fix Network Issues

Fix Network resolves the most common Windows networking issues by resetting the entire network stack systematically. It flushes the DNS cache, resets the Winsock catalog, renews DHCP leases, repairs TCP/IP configuration, and clears corrupted network state. The repair intelligently detects WiFi connections and skips operations that would cause disconnection (like adapter resets) on wireless. It handles both IPv4 and IPv6, resets proxy settings, and restores Windows Firewall to safe defaults. Takes about 2 minutes with a restart recommended for full effect.

Frequently Asked Questions

My phone is fine on the same Wi-Fi but this PC is not — will this repair help?▼
Yes — that exact pattern (other devices fine, one PC broken) points at this machine's network stack rather than the router or internet service, which is precisely what this repair resets.
Will it erase my saved Wi-Fi networks and passwords?▼
No — Wi-Fi profiles are stored separately from the stack state this repair resets. Custom static IP or DNS settings on an adapter may need re-entering afterwards.
