PC-MTU 2.4

PC‑MTU is a lightweight utility designed to help you discover, test, and optimize the Maximum Transmission Unit (MTU) on your PC. By identifying the largest packet size that traverses your network without fragmentation, it can improve throughput, reduce latency spikes, and minimize packet loss—especially over VPNs, PPPoE connections, and complex WAN paths.

Key capabilities:

• Automatic MTU discovery using non‑fragmented probe packets
• Clear guidance on recommended MTU values and how they affect performance
• Per‑interface adjustments (Ethernet, Wi‑Fi, and common tunnel/VPN adapters)
• One‑click apply and safe revert to previous settings
• Support for both IPv4 and IPv6
• Optional logging to track changes and test results

Whether you’re gaming, working remotely, or fine‑tuning a mixed network, PC‑MTU makes it straightforward to set an MTU that balances speed and reliability.
