Etherify Zero is a smart Windows 10/11 network optimizer for latency, jitter, throughput, and stability. It detects your hardware and network type, benchmarks where needed, and applies the appropriate optimizations for Wi Fi or Ethernet.
Profiles are selected automatically based on hardware and network type, with manual override available when needed.
Every change can be reviewed before applying, restored to Windows defaults, or rolled back using a system restore point.

Auto Optimize — automatic profile detection and full optimization
CPU / RSS — dynamically selects an RSS starting CPU from physical CPU topology instead of using a fixed processor number
MTU Detection — finds and verifies the largest usable packet size in ~16 seconds on average
DNS Optimization — benchmarks Cloudflare, Google, Quad9, OpenDNS, and AdGuard DNS and applies the best two based on latency and stability
TCP Optimization — profile based TCP tuning for latency, throughput, and stability
IPv6 Preference — choose IPv6 preference, IPv4 preference, or disable IPv6 transition mechanisms
Wi Fi Latency — optimized for low latency and stability
Ethernet Latency — optimized for responsiveness
Wi Fi Download — optimized for throughput
Profiles are selected automatically and can be manually overridden from the profile selector.
Adapter Restart — quick and hard restart options
Cache Reset — DNS, ARP, and Winsock
Reset to Defaults — restore Windows networking and congestion settings
Custom MTU — view or manually set MTU, including a 1280 preset
Congestion Controller — manually select the congestion control algorithm
Latency, jitter, and DNS benchmarking
Performance scores and rankings
Benchmark history
Plain language diagnostics
Info Tab — detailed CPU, RAM, GPU, IP, DNS, MTU, adapter, Wi Fi signal, interface metric, and other system and network information
Home — key actions, adapter information, profile status, pinned tools, and recommendations
Backups — named system restore points and rollback
Review Changes — preview changes before applying
Restart Indicator — shows when changes require a restart
Live Status — background operation status
Start on Login — optional delayed startup
- Windows 10 & 11 detection (optimize-aware)
- Wi-Fi & Ethernet detection (optimize-aware)
- Near 0% CPU / GPU use when idle
Etherify Zero does not apply a universal set of "gaming tweaks."
Configurations are selected according to the detected network type, hardware, and selected performance goal. Latency-oriented profiles prioritize responsiveness, while throughput-oriented profiles make different tradeoffs.
All optimizations can be reviewed before application and restored through the application's reset/backup mechanisms.
