About This Tool

WiFi Inspector is a domain-focused diagnostic tool that collects network-facing inputs such as RSSI, noise, channel, width, client count, and AP count to estimate throughput and interference risk.
It uses a transparent calculation flow: compute SNR from RSSI and noise, map SNR to representative MCS rates, apply contention overhead, and output practical recommendations.
Target users include homeowners, IT pros, and network admins who need quick sanity checks or deep dives into wireless issues. Unique differentiator is an integrated, rules-based scoring that translates radio metrics into concrete actions like 'switch to channel 6 on 20 MHz' or 'enable 80 MHz where allowed'.
Core features include input validation, regional channel mapping, advanced mode for multiple APs, and output dashboards with throughput estimates and channel overlap visualization.
Use cases include home improvement, small office troubleshooting, and retail environments evaluating guest networks.

Frequently Asked Questions

Find Quick Answers

What does WiFi Inspector estimate?

It provides a practical throughput estimate, interference risk score, and channel overlap analysis, plus concrete optimization actions you can apply to improve coverage and user experience.

Do I need specialized hardware?

No hardware beyond typical measurements is required. You can input observed RSSI, noise floor, and channel data, or import readings from common measurement apps, and receive actionable results.

How reliable are the estimates?

Estimates are approximate, based on standard wireless models. Real-world results depend on traffic patterns, client distribution, and environmental factors not fully captured by single-point inputs.

Can it handle multiple APs?

Basic mode analyzes a single AP. Advanced mode supports simple multi-AP scenarios with overlapping channels and provides allocation suggestions, while ignoring complex enterprise deployments.
