⚡ Introduction

RouterHub is a high-performance, privacy-focused Android application designed to put professional network administration, router management, device discovery, speed testing, and security auditing into your pocket.

Built from the ground up with Kotlin Coroutines, Jetpack Compose, Material 3, and Hardware Encryption, RouterHub eliminates the friction of discovering local IP addresses, accessing router dashboards, identifying connected Wi-Fi hosts, and auditing home networks for security vulnerabilities.

🆕 What's New in v1.2.0

• ⚡ Accurate Multi-Stream Speed Test: Resolved premature ~5s termination. Implemented full-duration TCP saturation (10s multi-stream download, 8s upload, 1.5–2s latency/jitter test) using Cloudflare Anycast edge servers with FCC/Ookla warm-up filtering.
• 📈 Live Throughput Wave (Sparkline): Real-time stream chart showing live speed fluctuations with gradient fill.
• 🎯 Dynamic Adaptive Speedometer: Gauge scale automatically scales (100, 250, 500, or 1000 Mbps) with radial graduation ticks, glowing pointer, and tabular digital readouts.
• 🎬 Network Capability Assessment: Automatic verdict for 4K/8K Video Streaming, Low-Latency Gaming, HD Video Conferencing, and Cloud Backups.
• 📱 UI & Layout Bug Fixes: Fixed top app bar title squishing, resolved "ONLI / NE" gateway badge line-breaks, fixed gateway router misclassification as "Smartphone/PC", added scroll clearance to prevent FAB overlap, and made WebView credential bar horizontally scrollable.
• 🛡️ DNS Security Auditor Fix: Resolved false-positive "Unrecognized External DNS Resolver" alerts by detecting Android Private DNS (DoT) and recognizing standard ISP resolvers as compliant.
• ✨ Silky Smooth Navigation: Added Compose Crossfade transitions across tabs and streamlined top app bar with overflow menu.

🚀 Module Deep-Dive

📡 1. Multi-Router Administration & Management (Click to Expand)

• Dynamic Gateway Resolver: Automatically identifies active gateway router IPs (ConnectivityManager & route tables) with dynamic 3s polling.
• Router Profiles: Store and manage configurations for multiple routers (home, office, secondary APs).
• Embedded Configuration Portal: Custom-tuned WebView with desktop user-agent switching, HTTP basic auth support, and self-signed SSL bypass for local router dashboards.
• Hardware Credential Security: Router login passwords encrypted via EncryptedSharedPreferences (AES-256 GCM + Android Keystore).

🔍 2. High-Speed Subnet & Port Scanner (Click to Expand)

• Concurrent Subnet Sweep: Asynchronously probes all 254 hosts on a /24 subnet using Kotlin Coroutine dispatchers.
• Categorized Device Identification: Auto-classifies hosts as Gateways & Routers, Smartphones & Mobile, Computers & Laptops, Smart TVs & Media, Smart Home & IoT, Printers & Cameras, or Network Storage.
• Comprehensive Host Diagnostics:
  • IP & MAC address resolution via ARP inspection (/proc/net/arp).
  • Protocol badges (HTTP, HTTPS, SSH, TELNET, SMB, RTSP, WEB).
  • Color-coded ping latency (⚡ 12ms green, 📶 48ms amber, 🐢 165ms red).
• Privacy Data Masking: One-tap top bar toggle to mask IP (192.168.1.***) and MAC (50:C7:BF:**:**:**) for privacy and screenshots.

🚀 3. Anycast Multi-Stream Speedometer Test (Click to Expand)

• Cloudflare Anycast CDN: High-bandwidth speed test engine powered by Cloudflare Anycast global edge servers (speed.cloudflare.com).
• Continuous Multi-Stream Saturation: Parallel coroutine download workers continuously streaming chunks for true TCP saturation over a full 10-second download and 8-second upload window.
• Dynamic Adaptive Speedometer: Radial graduation ticks with automatic scale switching (100, 250, 500, 1000 Mbps).
• Live Throughput Wave & Capabilities: Real-time sparkline speed curve and automated streaming/gaming/video call quality verdicts.
• Zero-Allocation Memory Engine: Static buffer reuse (REUSABLE_BUFFER), eliminating Garbage Collection overhead and OutOfMemory crashes.

🛡️ 4. Automated Wi-Fi Security Audit Engine (Click to Expand)

• 0–100 Security Rating: Real-time health score with color-coded severity levels (CRITICAL, HIGH, MEDIUM, LOW, INFO).
• Dedicated Rescan Button: On-demand security re-auditing button with real-time status animation.
• Multi-Point Vulnerability Checks:
  • Unencrypted HTTP router management portals.
  • Exposed high-risk legacy ports (Telnet 23, FTP 21, SMB 445).
  • Weak/default administrative credential exposure risks.
