This first task passively lists nearby Wi-Fi access points without connecting to a network or transmitting anything. Run it from the on-device UI or a serial CLI, not the WebUI on a single-board setup, where the Wi-Fi radio is already hosting GhostNet. Attach the board’s supported Wi-Fi antenna if it has an external antenna connector.
## On-device
- Open Menu → Wi-Fi → Scanning.
- Choose Scan Access Points.
- Wait for the scan to complete.
- Choose List Access Points to review the results.
## CLI
- Open the GhostESP serial terminal.
- Run scanap.
- Wait for the scan to finish.
- Run list -a to view the saved access-point list.
GhostESP lists nearby networks with their name, channel, signal strength, and manufacturer when available. If no networks appear, move closer to a known access point and try again.
## Troubleshooting
- No networks found: Confirm the board supports Wi-Fi, attach its antenna if applicable, move closer to an access point, and scan again.
- The scan stops immediately: Stop any active Wi-Fi task or portal, then retry.
