iPerf3 Client & Server vs WLAN Pros Toolbox

Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test. iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version. Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks. Key features: - Client and server modes - TCP/UDP tests, including bidirectional and reverse - Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU - Shortcuts automation + x-callback-url for power users - Saved server profiles and favorites - History with charts and CSV/JSON export - Detailed metrics: throughput, latency, jitter, packet loss Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions). Built for network engineers, sysadmins, and power users who need accurate, repeatable results.

WLAN Pros Toolbox is a free field companion for Wi-Fi and network professionals. No account. No ads. No tracking. Built by Wireless LAN Professionals. If you design, install, or troubleshoot Wi-Fi and networks for a living, this is the calculator and reference set you carry in your pocket, plus the live diagnostics you reach for on site. More than 120 tools, organized so you find the one you need fast. The reference tables and calculators work offline once the app is installed. The active diagnostics need a network connection to do their job. The app shows the tools each platform supports, and on iPhone and iPad some live Wi-Fi details use a companion Apple Shortcut you install once. CALCULATORS RF and signal math without the spreadsheet: - dBm / Watt converter - Free Space Path Loss (FSPL) - EIRP, Fresnel zone, link budget, fade margin - Cable loss, noise floor, RF attenuation by material - Antenna downtilt and downtilt coverage - ITU rain fade, earth curvature - GPS: lat/long conversion, distance and bearing, midpoint, final point - Wavelength, metric conversion, hex / ASCII / binary - PoE budget, throughput by MCS, capacity planning, point-to-point link check LIVE DIAGNOSTICS The active tools for the field: - Interface information: local IPs, gateway, DNS, link details - Ping (ICMP and TCP), ping sweep, traceroute - DNS lookup over DNS-over-HTTPS (A, AAAA, MX, TXT, NS, SOA, PTR, SRV, CAA, SPF) - WHOIS, BGP / ASN lookup, IP geolocation - Port scan, SSL/TLS certificate inspection, HTTP header inspection - Network discovery, ARP/NDP neighbor lookup, MAC vendor OUI lookup - Wake-on-LAN, packet sender - Network quality: latency, jitter, loss, throughput, and reachability checks - Wi-Fi information: live link details for the connected network CHECK MY CONNECTION A plain-language helper that answers one question for anyone, not just pros: is it your Wi-Fi or your internet? Start here when someone hands you a slow connection and wants an answer. QUICK REFERENCE The tables you keep looking up: - 802.11 standards, MCS index, Wi-Fi channels, channel bonding map - Signal thresholds, roaming parameters, AP placement guidance - WPA security matrix, 802.11 reason codes, frame exchange - PoE class and wattage, well-known ports - Cabling: Ethernet pinout, Ethernet cable, coax, fiber, RF connectors - dB reference, spectrum allocations, OSI model, Wi-Fi glossary REFERENCE AND LAB HOW-TOS - Network CLI commands (Windows and macOS/Linux) - Linux and WLAN commands, monitor mode - Wireshark 802.11 display and capture filters (reference cheat sheets, not a packet capture) - Educational resources from independent Wi-Fi authors - Field checklists for AP install and client testing Free for the community.
