WLAN Pros Toolbox

WLAN Pros Toolbox gives Wi-Fi pros, IT help desks, instructors and students 260+ network tools, plus a Wireless Classroom of lessons and simulators. Free. No account. No ads. No data collected. Built by Keith Parsons, CWNE #3, and Wireless LAN Professionals.

Everything is grouped so you find the tool you need fast: live network tests, calculators, reference tables and the Wireless Classroom.

The Wireless Classroom
- 30 Guided Lessons in plain language, where the pictures do most of the teaching: Find My, Starlink, Wi-Fi Calling, Travel Routers, Captive Portals, Mesh and Extenders, One Talker per Channel, Is Your Router Too Old?, and more.
- 50 interactive simulators: Wi-Fi Through a Wall, Multipath, Rate vs Range, Modulation, Polarization, OFDMA vs MU-MIMO, MIMO and Beamforming, Airtime Fairness, Multi-Link Operation (Wi-Fi 7), Roaming Walk, DFS and Radar, 802.1X and EAP.
- Presenter mode for the projector, one step at a time.
- A Teacher's Guide and a Field Manual for instructors.

Is It Your Wi-Fi or Your Internet?
Test My Connection helps answer the question everyone asks, in plain language. Start here when someone hands you a slow connection.

Networking Tools
Ping, traceroute, DNS, WHOIS, BGP/ASN, MAC vendor lookup, IP geolocation, port scan, HTTP and SSL/TLS inspectors, NTP, Wake-on-LAN.

Calculators
Free space path loss, Fresnel zone, link budget, EIRP, dBm and watts, rain fade, noise floor, antenna downtilt, capacity planner, SSID airtime, throughput, PoE budget, IP subnets, GPS.

Quick Reference
103 tables in 13 topics: channels, 802.11 standards, MCS index, security and authentication, reason codes, cabling and connectors, ports, and a Wireless Glossary of 123 plain-language terms in English, Spanish, French, Italian and German.

Reference tables and calculators work offline. Live tests need a network connection. iOS limits what apps can read about Wi-Fi, so on iPhone and iPad some live Wi-Fi details come from an optional companion Apple Shortcut.
