WhyFi 1.4.3

July 4, 2026

WhyFi is a lightweight macOS utility designed to diagnose and explain Wi-Fi performance issues in real time. Instead of guessing why your connection is slow, WhyFi continuously monitors your network and breaks down problems into clear categories such as Wi-Fi signal, router performance, ISP issues, and DNS delays.

By analyzing each layer of your connection, WhyFi helps you identify the exact cause of slow speeds, high latency, or unstable connections — and provides actionable insights to resolve them quickly.

Built as a menu bar app, it runs quietly in the background and gives you instant visibility into your network health without interrupting your workflow.
