[AI Router] WiFi Insight
1. Overview
WiFi Insight visualizes invisible wireless environment data—band/channel usage, interference heatmap, and reasons for channel or bandwidth changes—using intuitive charts. It helps you quickly decide whether to change channels, adjust bandwidth, move devices, or keep your current setup.
2. What Problems Does It Target?
- Reveals if your current channel is crowded (avoiding blind manual channel locking).
- Explains why your router automatically changes channel/bandwidth (event tags).
- Distinguishes interference sources: other Wi-Fi, non-Wi-Fi devices, regulations (DFS/RADAR).
- Provides a basis for narrowing bandwidth, switching between 2.4/5/6 GHz bands, or adding mesh nodes.
3. Interface Guide
(1) Band switch: toggle between 2.4 / 5 / 6 GHz.
(2) Event list: shows each channel/bandwidth change (with time and reason tags).
(3) In Channel Interference line chart: shows the percentage of interference on the current channel over time.
(4) Spectrum heatmap: displays interference intensity across all channels in the selected band; deeper colors mean higher interference. The blue box marks the router's active channel (or bandwidth range).
(5) Filter buttons: Channel in use / DFS / Others WiFi interference / NonWiFi interference, to control what is shown.
(6) Advanced settings: top-right menu lets you enable/disable detection and auto-refresh, and set the chart time range (10M / 1H / 12H / 1D).
4. Troubleshooting Common Connection Issues
| Scenario | How to Judge from the Interface | Recommended Action |
| Slow Wi-Fi? | Check In Channel Interference trend + Spectrum heatmap | Switch to a cleaner channel or band |
| Why did my channel just change? | Event list tags (Optimized / Manual / RADAR, etc.) | Decide whether to keep auto or switch to manual settings |
| Should I use 160MHz? | Check interference in the Spectrum heatmap | If crowded, use 80/40MHz; if clean, keep wide bandwidth |
| 2.4GHz connection issues | NonWiFi interference and Others WiFi interference indicators | Remove interfering devices (microwave, other 2.4GHz devices) or move the router |
| High latency on 2.4GHz devices | High NonWiFi/Others WiFi interference | Switch to a cleaner channel or band |
| High NonWiFi indicator | External non-Wi-Fi device interference | Remove interfering devices or change router location |
5. Chart Colors and Tag Meanings
| Element | Meaning |
| Darker heatmap colors | Higher interference, crowded channels or more noise |
| Red/dark blocks | High interference, channel not recommended |
| Blue box | Current active channel or bandwidth range |
| Tag: Initial auto selection | Channel selected automatically at boot or first setup |
| Tag: Optimized automatically | System auto-adjusts based on interference or regulations |
| Tag: Manually configured | User manually changed settings |
| Tag: Adaptive Bandwidth Expand/Reduce | System dynamically adjusts bandwidth for balance |
| Tag: Regulatory (RADAR) | Radar detected, must leave or change channel |
| Tag: Regulatory (Channel conflict) | Channel conflict detected, must change channel |
| Tag: Interference | High environmental interference, should change channel |
| Tag: Interference (TXFAIL) | High interference causing transmission failures, should change channel |
6. Glossary
Term | Description | Notes |
| Band | Wireless operating frequency range, commonly 2.4 GHz, 5 GHz, 6 GHz. Each has different channel counts, penetration, and interference sources. 2.4 GHz penetrates walls well but is easily interfered; 5/6 GHz have more channels and speed but less penetration. | Switch bands based on device support and crowding to avoid interference |
| Channel | Each band contains multiple channels; the router communicates on a selected channel. | Watch for crowded channels; overlapping or heavily used channels cause interference. Choose less-used or cleaner channels |
| Spectrum | Interference distribution across all channels in a band | Use to find cleaner channels |
| In Channel Interference | Percentage of interference on the current channel over time | If high, consider changing channel or narrowing bandwidth |
| Band (2.4/5/6 GHz) | Different frequency ranges; higher bands have more channels and less interference | If possible, connect devices to higher bands to avoid crowding |
| Channel Width (20/40/80/160 MHz) | Spectrum width used; wider means higher speed but more prone to interference | If crowded, narrow width for stability; if clean, keep wide for speed |
| DFS | Dynamic Frequency Selection: regulatory requirement—when radar is detected, router must leave the affected channel and switch. Prevents interference with weather/aviation radar. | If radar is frequent, disable "auto-select DFS channels" to avoid frequent disconnects |
| NonWiFi interference | Noise from non-Wi-Fi devices | Remove interference sources or move router |
| Others WiFi interference | Interference from other Wi-Fi APs nearby | If severe, switch to less-used channel/band |
7. Best Practices
- Prefer automatic channel selection to avoid locking onto crowded channels.
- If the heatmap is mostly red for a long time, narrow bandwidth or switch bands.
- If 2.4 GHz is noisy, don't force 40MHz; use 5 or 6 GHz if you need speed.
8. Notes
- Features and interface may vary by region due to regulations.
- When the router switches channels, all devices on that channel will briefly disconnect and reconnect automatically. If interference is still acceptable, the system will try to keep the current channel to minimize interruptions.
