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.
