DIM-Fi: WiFi Network Analyzer

DIM-Fi is the ultimate all-in-one Wi-Fi analyzer and network diagnostic toolkit designed to help you monitor, optimize, and secure your local network. Whether you are a competitive gamer trying to fix ping spikes, an IT professional conducting a cyber security audit, or just someone looking to eliminate Wi-Fi dead zones, DIM-Fi provides enterprise-grade telemetry in an intuitive mobile app.
Stop guessing why your internet is slow. Instantly diagnose network anomalies, track connected devices, and ensure your router operates at peak performance.

ONE-TAP NETWORK AUDIT & DIAGNOSTICS
AI Root Cause Analysis: Instantly evaluate your overall network health. Our heuristic engine detects weak signals, channel congestion, high jitter, and rogue DHCP servers, providing actionable troubleshooting steps.
Visual Topology Map: See exactly who is on your Wi-Fi. Our discovery engine scans your subnet (via ARP, mDNS, SSDP) to identify all active devices, rendering a real-time node-link hierarchy map.

INTERNET PERFORMANCE & QOE TEST
Bufferbloat & Responsiveness Test: Go beyond basic speed tests. Measure working latency under bidirectional load to calculate bufferbloat delta and IETF RPM (Round-trips Per Minute).
Application Readiness (MOS): Get definitive Quality of Experience scores to see if your network is truly ready for Competitive Gaming, 4K Streaming, or Zoom Video Calls.
DNS Benchmark: Compare response times across top public DNS resolvers (Cloudflare, Google, Quad9) against your local ISP to find the fastest connection.

WI-FI SURVEYOR & HEATMAP
Spectrum Analyzer (2.4, 5 & 6 GHz): Identify overlapping channels and interference. DIM-Fi recommends the cleanest frequency for your router to boost speeds.
2D Signal Heatmap: Upload floorplans and map out spatial signal coverage to locate Wi-Fi dead spots.
Sub-Meter Ranging (802.11mc): Utilize Hardware Fine Timing Measurement (FTM) to measure the physical distance to compatible Access Points with sub-meter accuracy (±30 cm).

CYBER SECURITY & PRIVACY AUDIT
Rogue AP & Evil Twin Detection: Protect yourself on public Wi-Fi by detecting counterfeit access points spoofing your network.
Hidden Camera Finder: Audit hotel or Airbnb networks to locate stealthy IP surveillance cameras via RTSP/ONVIF port probes.
ISP DNS Hijacking Probe: Detect if your internet provider is stealthily redirecting unencrypted DNS traffic through censorship middleboxes.
Vulnerability Scanner: Check for Layer-2 client isolation, PMF deauthentication flaws, and Man-In-The-Middle (MITM) ARP poisoning attacks.

DEEP HARDWARE INSPECTOR (PRO)
Advanced Telemetry: Monitor Wi-Fi 7 Multi-Link Operation (MLO), PHY metrics, MU-MIMO spatial streams, and parse raw 802.11 Information Elements (IE).
Remote Router Admin: Connect to OpenWrt routers to configure SQM CAKE QoS scripts and eliminate bufferbloat remotely.
Live Packet Sniffer: Supports external USB OTG Wi-Fi dongles to capture raw 802.11 frames.

100% LOCAL PROCESSING
Your privacy is our priority. All network scans, port probes, and device discovery processes run entirely on-device. We do NOT collect, track, or send your local network data to remote servers.
Take full control of your digital environment. Download DIM-Fi today to optimize your router, secure your data, and experience a flawless connection!
