Universal Node Congestion Tracker

About

Take control of your network diagnostics. Document ISP drops, monitor line noise, and hold your internet provider accountable with real-time hardware telemetry logging.

Have you ever experienced sudden lag spikes, dropped video calls, or total internet blackouts, only for your ISP to tell you "everything looks fine on our end"?

The Universal Node Congestion Tracker is a powerful, self-hosted diagnostic tool designed to bridge the gap between your modem's raw hardware data and your right to a stable connection. It automates the tedious task of monitoring local cable nodes and translates complex RF (Radio Frequency) diagnostics into clear, actionable history logs.

 Key Features
Automated Background Tracking: Wakes up every 5 minutes to securely log your connection stats. No more manually refreshing confusing modem pages.

Smart Content Routing: Automatically identifies your modem type (Netgear, Arris Surfboard, or ISP-provided Technicolor gateways) and loads the exact scraping driver needed.

Interactive Analytics Dashboard: View your connection history on beautiful, interactive HTML5 canvas charts. Hover over any point to view precise timestamps, decibel drops, and packet errors.

Signal Quality Breakdown: Color-coded pie charts instantly categorize your day's performance into Pristine, Degraded, or Severe Noise tiers.

Accountability Metrics: Tracks your worst-performing channel's SNR (Signal-to-Noise Ratio) and counts Uncorrectable Codewords (the primary culprit behind packet loss and drops).

Data Portability: Seamlessly import or export historical logs using standard CSV format to build an undeniable, weeks-long portfolio of network failures to hand directly to field technicians.

 How It Works
Leave your modem’s internal status page (e.g., 192.168.100.1 or 192.168.0.1) open in a background tab.

The extension silently extracts your downstream bonding channel tables without interrupting your web browsing.

If your modem logs out or your session expires, the extension fires a native desktop notification to let you know action is required.

Open the History Dashboard at any time to review your data, detect peak neighborhood congestion hours, and export your timeline.

 Privacy First
100% Self-Hosted: Your network logs are stored strictly inside your local browser storage. None of your data, IP addresses, or network metrics are ever transmitted to an external server.

Zero Dependencies: Built entirely with lean, native vanilla JavaScript and standard Web APIs.

Stop guessing why your internet is dropping. Download the Universal Node Congestion Tracker today and get the data you need to fix your connection for good!
