Background Scanning

Run periodic AP/STA scans in the background and review long-term history charts.

Background Scanning

Background Scanning lets your device run periodic Wi-Fi scans and save results over time so you can track trends, not just live snapshots.

  • AP Scan: Periodic access-point discovery.
  • STA Scan: Periodic station/client discovery.
  • History View: Saved samples are grouped and shown in charts.

Before You Start

  • Insert an SD card if you want scan history saved over time.
  • Keep the device powered while background scanning is enabled.
  • Connect the device to Wi-Fi for the most accurate date/time on charts.

How to Use

  1. Open the web interface and go to the Wi-Fi section.
  2. Enable Background Scanning.
  3. Set your scan intervals.
  4. Leave the device running.
  5. Open History to review activity over time.

Reading the Charts

  • Newer entries display in your local date/time format.
  • Older history may appear as approximate time if it was recorded before clock sync was available.
  • If no reliable clock is available yet, labels may appear as relative uptime (T+...).

Best Practices

  • Use intervals of 5-10 minutes for normal monitoring.
  • Use shorter intervals only when you need higher detail.
  • Keep enough free space on the SD card for long-term logging.
  • Let scans run for at least a few hours before evaluating trends.

Troubleshooting

  • No history appears: Confirm an SD card is inserted and recognized.
  • History is outdated: Make sure Background Scanning is enabled and the device has stayed powered on.
  • Time labels look odd: Connect the device to Wi-Fi and allow a few minutes for clock correction.
  • Not enough data: Wait longer so more scan points are collected.
