🔍 How It Works

AMI uses a multi-layered approach to determine internet connectivity:

1. Parallel Ping Tests: Simultaneously pings multiple hosts to detect connectivity
2. HTTP Verification: Attempts an HTTP request to verify web access
3. Local Network Check: Tests gateway connectivity to distinguish local vs internet issues
4. Statistical Analysis: Analyzes success rate and latency to determine stability

Status Determination

• 🟢 ✓ Online: All tests pass, latency < threshold, minimal packet loss
• 🟡 ! Unstable: Some tests pass but high latency or significant packet loss
• 🔴 ✕ Offline: No successful connections

Accessibility Note: Each status uses a unique symbol (✓, !, ✕) in addition to color, ensuring users with color vision deficiencies can distinguish states.

⚙️ Advanced Features

Auto-Start with Windows

To enable auto-start:

1. Open config.json
2. Set "auto_start": true under "startup"
3. Restart AMI

Alternatively, create a shortcut to AMI.exe in your Startup folder:

%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup

Silent Mode

For minimal interruptions:

1. Open config.json
2. Set "silent_mode": true under "notifications"
3. AMI will still log events but won't show notifications

Custom Test Hosts

You can add or modify test hosts:

"ping_hosts": [
  "8.8.8.8",           // Google DNS
  "1.1.1.1",           // Cloudflare DNS
  "your.server.com"    // Your custom host
]

🐛 Troubleshooting

Icon Doesn't Appear in System Tray

• Check Task Manager for running AMI process
• Try running as Administrator (some networks require elevated privileges)
• Check if system tray icons are hidden (click the arrow in taskbar)

High CPU Usage

• Increase polling_interval in config.json
• Reduce number of ping_hosts
• Disable enable_http_test

False Offline Status

• Check if your firewall blocks ICMP (ping)
• Add firewall exceptions for AMI.exe
• Try different ping_hosts (some networks block certain IPs)

No Notifications

• Check Windows notification settings
• Ensure notifications.enabled is true in config.json
• Check if silent mode is disabled

♿ Accessibility Statement

AMI is designed to be accessible to all users, including those with visual impairments:

• Color Vision Deficiency Support: All status information uses symbols (✓, !, ✕) alongside colors
• High Contrast: Large, clear icons with strong contrast ratios
• WCAG 2.1 Compliance: Meets Level AA standards for visual presentation
• Universal Design: Symbols are internationally recognized and culturally neutral

Supported conditions:
