WhyFi 1.4.2 for Mac – Wi-Fi Diagnostic & Troubleshooting Tool

WhyFi is a handy menu bar utility for macOS that continuously monitors your network connection and quickly shows you exactly why your Wi-Fi is slow or unstable. It tracks your connection health across multiple levels, including Wi-Fi signal strength, router latency, internet service provider (ISP) quality, and DNS performance.

If you’ve ever experienced sudden drops during video calls or painfully slow loading times, WhyFi eliminates the guesswork. Using intuitive color-coded indicators, it highlights exactly where the bottleneck is occurring and provides actionable advice on how to fix it.
