WiFi Commander: WiFi Analyzer

WiFi Commander is the WiFi analyzer and network toolkit for people who make Wi-Fi work under pressure: AV technicians, expo and trade-show crews, conference and event IT, booth staff and installers. Walk into a packed exhibit hall with 150 networks fighting for air and see in seconds which channels are jammed, where the signal dies and who is on your booth network. Every reading is real and never made up.

📊 CHANNEL GRAPH & ADVISOR
• A colorblind-safe spectrum graph for 2.4, 5 and 6 GHz shows exactly which channels are crowded.
• A suggested least-congested channel for your access point, with DFS channels flagged and your region taken into account.

📡 WI-FI ANALYZER
• Every network in range with signal (dBm), channel, band, width, security and Wi-Fi generation.
• Venue and mesh networks with the same name group into one row; expand to compare each access point.
• Vendor names and a signal-history sparkline per access point.

🗺️ SITE SURVEY HEATMAPS
• Import a floor plan (image or PDF), tap where you stand to record a real reading, and see a coverage heatmap.
• Export a PNG, CSV, JSON or a one-page PDF report with the method and limits spelled out.

📶 LIVE SIGNAL METER & WALK TEST
• Your link's signal once a second, with optional tone and vibration to hunt dead spots without looking.
• Walk test with coverage breakdown, weakest point and access-point hand-offs, plus a roaming timeline.

🖥️ LAN DEVICE SCANNER
• Find devices on your network with ping, ARP, Bonjour/mDNS, UPnP, NetBIOS and reverse DNS.
• Addresses, vendors, open ports, a best-guess device type and advertised services. Label what you know.
• Save snapshots and compare later to spot new or missing devices. Wake-on-LAN included.

⚡ SPEED, BUFFERBLOAT & INTERNET TESTS
• Wi-Fi speed test for download and upload.
• Bufferbloat grade (A+ to F): the hidden reason video calls and streams stutter under load.
• Internet quality, latency to popular services, and a DNS check for encryption and hijacking.

🛠️ NETWORK TOOLS
• Ping, traceroute, DNS lookup (A, AAAA, CNAME, MX, NS, PTR, SOA, TXT) and TCP port check.
• Every run is saved to History and exports to CSV or JSON.

✅ AND MORE
• Network report card, captive-portal detection, open-network warnings, Wi-Fi QR sharing for your own network and a home-screen widget.

BUILT FOR THE SHOW FLOOR
• AV techs checking congestion before a keynote or breakout session
• Expo and trade-show booth staff finding a clean channel in a crowded hall

• Installers and integrators documenting a site survey
• At home: finding dead zones, picking the best router channel, seeing who's connected

WHY TRUST IT
No account, no sign-up, no cloud. Scans, device lists, surveys and history stay on your phone unless you export or share them. Internet tests contact a public server only when you start them. WiFi Commander only observes networks and tests the network you're on; it never guesses or cracks passwords. Android requires location permission to list Wi-Fi networks; you are never tracked.

Good to know: readings come from your phone's Wi-Fi chip and vary between devices, and Android limits how often apps may scan.

Every measurement, tool and export is free, with a small banner on two list screens. No scan limits, no paywalled exports.

Install WiFi Commander and own the airwaves at your next show.
